Travel Considerations
We are travelling to Halong Bay in August – one of the most beautiful times to conveniently
view the charming grace of the bay. Northern Vietnam (Halong Bay’s geographical location
specifically) has a temperate climate with the annual average temperature range from 22oC to
27oC (UNESCO 2014), followed by hot, humid summers and cold, dry winters. The land’s
climate is determined largely by the activities of monsoons, or seasonal winds. Southeasterly
winds hit Halong Bay from May to September, bringing rainy season with drizzle weather while
northerly and northeasterly winds dominate from October to August. Cloudy days, light rain, and
unfortunate fogs can occur during February to April and frequent tropical storms are expected
from May to September (UNESCO 2014). For these reasons, the best time to visit Halong Bay is
from April to May, or August to November. Travelers should bring comfortable lightweight
cotton clothing (as well as warmer clothes if travelling in winter times), umbrellas or raincoats,
swimming suits, sunglasses, sunscreen of SPF 15 or higher, insect repellent or any other allergyrelated medications to be able to fully participate in various exciting activities throughout our
breathtaking journey.
DAY 1: Hon Gai Harbour – Ha Long Bay – Bai Tu Long Bay
All travelers are responsible for arrival at Hon Gai Harbour on time at 9 a.m. to start our
enthusiastic trip to discover the beauty of Ha Long Bay – also our first stop on the journey.

interesting facts about the land. We will then move to Bai Tu Long Bay, a smaller area of the
main bay that is considered to be the hidden gem. The peaceful yet wild environment of Bai Tu
Long Bay will give you a whole new experience of nature while pleasantly enjoying kayaking
activities provided by our crews. To finish the day off, nutritious traditional Vietnamese cuisine
will be served before overnight on board.

Halong Bay
Located in the Gulf of
Tonkin,
Quang
Ninh
Province, Halong Bay is
well-known as a UNESCO
World Heritage Site since
1994, one of the New 7
Wonders of Nature in 2012,
for its scenic and geological
values. Halong Bay includes
approximately 1,600 islands
and islets, an abundance of
lakes and cavernous features.
The bay used to be a deep sea
during previous historic eras
yet through over 500 millions
years of development, the

marine hydrological process,
and Karst erosion have formed such spectacular view which Ho Chi Minh proudly called “the
wonder that one cannot impart to others” (Halongbay.info 2014). Visiting Halong Bay, travelers
have a chance to discover its geomorphology – a drowned karst landscape accompanied by a
complicated system of primitive caves, which can be divided into three types: old phreatic caves
below water table, old karstic foot caves at base level and marine notch caves at sea level
(HalongBay.info 2014). The biosystems of Halong is also very unique as there are both oceanic
and seashore biosystem and a tropical evergreen biosystem. The Bay is located at the Tropic of
Cancer areas (20o43’N – 21o09’N) with four distinct seasons, average temperature of 27oC in
summer and an annual rainfall of 2,005.4mm (UNESCO 2014). Additionally, Halong Bay is also
rich in biodiversity of various conserved floral species such as mangroves, corals and tung ang.
Besides all these scientific data, tourists are attracted to Halong for its tranquil atmosphere and
graceful charm as described in a Vietnamese tale to be the “descending dragon bay”, mostly
untouched and unharmed by human activities and development.
Bai Tu Long Bay
Bai Tu Long Bay is known as a “hidden gem” located to the North of the renowed Ha Long
Bay. Bai Tu Long is much quieter since there are not a lot of cruises offered to visit this
untouched area, which in contrast is growing to be a promising tourist attraction in future times.
The Bay also possesses breath-taking karst features with fascinating system of caves, islands and
islets, formed by large deposit of limestone, hydrolysis, tropical climate and the slow tectonic
uplift – similar to that of Halong. However, most of these lands are inhibited by humans, largely
living on floating villages, fed on fishing and fish-farming – a unique practice to discover. Bai
Tu Long Bay is better known for its National Park, set up by the federal government in 2001.
The park is home to 494 different plant species, 37 animals, 96 bird species, 15 amphibian

(also known as seacow) – a large
whale-like sea mammal listed in
Vietnam’s Red Book, is one of the
most valuable (scientifically and
economically) divisions in this
ecosystem. Different projects have
been carried out to help protect and
preserve such diverse ecosystem of
Bai Tu Long Bay.

DAY 2 – ACTIVITIES
Lan Ha Bay
Lan Ha Bay is an extension of
Ha Long Bay located at the
southeast of Cat Ba Island and
lies in a different province of
Vietnam – a fair distance from
Halong City, which is one of the
reasons for its preservation from
tourism and protection of
wilderness. Thus, travelers will
be blown away because of the
isolated and bewildered beauty
of Lan Ha Bay, the deep blue
ocean and unique limestone
pinnacles – “rock wonder in the
sky” (Nguyen Trai – Vietnamese
Figure 3: Kayaking on Lan Ha Bay
poet). Despite having similar

geographical
values
and
characteristics to Halong Bay, Lan Ha Bay is noted for its numerous amount (approximately
400) of small white sand beaches scattered throughout 7,000 hectares – a home for around 200
species of fish, 500 species of mollusk, 400 arthropods and other larger marine animals such as
seals and dolphins (365Travel 2014). Lan Ha Bay also preserves a distinctive environment for
soft coral reefs – such important indicator a healthy ecosystem, having significant niche in
protecting coastlines from effects of tidal waves, tropical storms, provide shelter, food and
nutrients source for marine organisms and so on yet are extremely vulnerable to environmental
changes, making it one of the most concerned species to be preserved. Tourists can participate in
various activities while touring the bay, such as sailing, guided kayaking, rock-climbing,
swimming on private spot of sandy beaches or diving into the transparent azure sea to discover
the colorful corals and study the important need to preserve such biological wonder.
Cat Ba Island
Cat Ba Island is located 30 miles to the east of Hai Phong City, southern part of Halong Bay, and
is the largest out of 366 islands in the region of Cat Ba Archipelago. Its beauty is defined by the
uniform charm of Karst landscape invaded by the sea, steep towering islands with vast relief.
The island is known for its diversified natural habitats such as “tropical limestone forest […]

coral terraces, freshwater wetland areas, tidal flats, mangrove forests and willow swamp.”
(Munster 2014). Cat Ba Island is also a wonderful area of endangered species preservation.
Besides having the essentiality of coral reefs – the indicator of environmental health (since it is
vulnerable to climate changes and have specific requirements to persist), the marine ecosystem
here is also conserved and purified by the existence of mangroves – plants of equal importance to
corals that help protect land from erosion, shorelines from ecological and natural disasters such
as hurricanes, provide a nursing habitat for threatened species accompanied by various symbiotic
relationships. The island’s national park is the first to be established in 1986 with both terrestrial
and marine ecosystems, covering a vast field of important biodiversity recognized as a UNESCO
Man and Biosphere Reserve in 2004. The Cat Ba National Park has recorded more than 1,500
unique plant species, 4 types of true cave snails; a divergent of crabs, reptiles as well as bats
species are continually being found until present day (Ray 2009). One well-known preservation
effort is the Cat Ba Langur conservation project to protect langurs – one of the most critically
primate species listed in the World Conservation Union with only about 60 individuals living
captive and in the wild. These langurs are believed to have migrated to the island of Cat Ba long
before the period of glacial ice melting (approximately 10,000 years ago) that led to the creation
of Ha Long Bay and can only be found nowadays within the island or at Cuc Phuong National
Park, Vietnam.

Surprise Grotto & Thien Canh Son Cave
Karst topography is characterized by large accumulation of limestone caverns and extensive cave
systems, which Halong Bay is the most vivid example of such geological formation,
demonstrated lively through the Surprise Grotto and Thien Canh Son Cave. Surprise Grotto and
Thien Canh Son Cave are two of many cave systems in Halong Bay that are formed trough the
process of dissolving limestone bedrock during millennia. Such occurrence is known as
hydrolysis and carbonation. When being exposed to water, faults and cracks in limestone soon
widen and dissolve to gradually create caves and tunnels. This process is quickened by the
accumulation of carbonic acid in natural rainwater, which concentration is higher in tropical
areas due to vegetative abundance. Surprise Grotto, found and named (Grotte des surprises) by
the French in 1901, is located on Bo Hon Island at the center of Halong Bay and covers an area
of 12.200sq meters at the elevation of 82ft
above sea level (about one-third in
comparison to Cupertino, California). The
cave is divided into two chambers: a
narrow entrance and a spacious main
chamber with up to 30-meter roof.
Surprise Grotto is filled with various
species of plants and birds accumulated in
a region called a “royal garden” with a
clear pond at the center of the main
chamber; colorful and elegant lights also
adds extra delicacy to the overall
enchanted view.

Secondly, Thien Canh Son Cave is a
smaller formation located in Bai Tu Long
Bay, covering an area of 2000sq meters.
The name “Thien Canh Son” can be
translated as Heavenly Mountain, as to
explain the cave’s geographical location:
below the forest canopy and a stone cliff
(HolidaysVietnam 2014). Despite being
inferior in size in comparison to Surprise
Grotto, Thien Canh Son Cave is wellknown for its wild beauty of a charmed
decoration of various stone statues
picturing elephants, seals, lotus, shiny
ceiling with sparking stalactites. The cave
is also a popular spot for tourist visits to
have romantic dinners – an experience that
travelers enjoy upon vacationing in Halong.

Cong Do Island
Being inferior in size in comparison to the Cat Ba Island and Cat Ba Archipelago, Cong Do
Island yet conserves its own russet beauty with 23,363sq kilometers of island, mountains
(occupying the highest peak of 172 meters) and a numerous amount of natural salt lakes, or
lagoons, provide a site for a diverse quantity of marine animals as well as plants preserved in
good condition. Cong Do Island is located at the southeast of Halong Bay, in the region of Bai
Tu Long Bay – a core area of the bay that is also recognized as a World Natural Heritage Site.
The formation of lagoons on Cong Do Island is the separation of the body of salt water by
sandbank and coral reef barrier from the deeper sea that ventures the Halong Bay. These blue

mirror-like natural lakes are homes to lots of species such as shrimps, crabs, fishes, squids,
seahorses, seaweeds and algae. The symbiotic relationship of mutualism between algae and the
growth of corals are carefully studied as corals depend largely on the oxygen given off by algae
through photosynthesis process while simultaneously providing algae with nutrients and a place
to live. Thus, 700 meters long and 300 meters wide of pristine coral reef on the island is
maintained in healthy condition exhibits a vast range of variety with rare species such as red
corals coral reef horns. The biome of limestone mountains surrounding is evergreen tropical
forest with an abundance of vegetation of tall hardwoods with broad leaves trees. Travelers to the
island can enjoy the biological values it brings as well as participating in other activities such as
trekking, kayaking and scuba-diving. Cong Do Island was also once found to be the most
popular trade point, known as Van Don port, of ancient Vietnamese dynasties with other foreign
countries, having important commercial means and values. As a result, plans are being measured
to successfully build an international airport in this favorable condition of Vietnam to promote
economics and tourism opportunities.

Ba Ham Lake is located on the southwest side of Halong Bay, in the region of Lan Ha Bay and is
famous for its unique structure, which can be described as an “enclosed world inside Halong
Bay” (Ministry of Foreign Affair 2014). The lake comprises of three other smaller lakes, walled
and connected through a system of tunnels, hence explains the name Ba Ham (three tunnels). In
attribution to the pristine beauty of the World Natural Heritage Site, Ba Ham Lake also preserves
its instinctive elegance, with the a transparent water body that can be seen through to observe the
activities of marine life underneath, protected against human’s modernized effects. The entrance
to the first lake is 150 meters long, 10 meters wide and 1.5-2 meters high. During the journey
through the first tunnel, travelers can also tour the second lake, the largest one of the three
wonders, covering about 1000sq meters, through an entrance on the right, or the third lake, the
smallest one exhibiting an area of 600sq meters, on the left. Ba Ham lake can only be visited
during low tides since the height of its entrance is relatively short compared to the majestic
limestone structure above, and would be dangerous to sail through during high tides. Having
such distinctive features, entrance to the lake is ornate with colorful and strangely shaped
stalactites, formed by the process of carbonation, as dissolved carbon and water vapor in the
atmosphere creates carbonic acid, comes in contact with the roof and gradually construct the
structure. Being surrounded by mountains, Ba Ham Lake is silent, having a tranquil atmosphere
that can be disturbed by any small sounds of human speculation. Travelers will be amazed to see
such vast natural beauty after a cruise in the cave’s darkness – an experience that is unique to Ba
Ham Lake. The lake has such a prosperous biodiversity with numerous tropical plants of various
species (slipper orchids, Livistona halongensis, Halong Cycas, etc.) and an abundance of animals
such as yellow-haired monkey (langurs), flying squirrels, silver-headed parrots, different breeds
of bats, butterflies and so on. Ba Ham Lake is one of the most beautiful spots to be witness in
Halong Bay and has great potential for attractive ecological tours.
Yen Tu Mountain
“Rambling along a path of pines,
Lone village lost in the mists.
The tide returns, the flute recedes o’er the river,
The sky broadens, cloud tipped trees.
Roosting birds flutter in the clear dew,
Cold fish jump in the jade tarn.
Where did the flute player go?
Lone on the mountain west.”
(Gino Pagliaccetti; translated from a poem written
by Chu Van An about Yen Tu Mountain).

Dong Pagoda at the summit as representation of such great belief in Buddhism of society ever
since Tran Dynasty. The mountain occupies a diverse plant and animal system that it is also
recognized as a nature preservation region. At the peak of the mountain, travelers can have a
view of the peaceful scene below, comprises of green plantation and Halong Bay in favorable
condition, since precipitation increases largely in winter times causing water vapor to accumulate
and form as denser clouds, blocking the view. Hikers to mountains have to travel the total length
of 6000meters in decreasing air pressure condition that they believe to show the ultimate
commitment and seek vindication for their sins, despite the new modern cable car technique
installed in 2002. On the other hand, the landscape is also facing serious natural resource
depletion as 12,000ha of primary forest area have been lost on the course of five years, 20052010 (Hoang 2012). These forest lost will take decades to recover and may not be in such
exuberant condition as it was, thus increase risk of flood events and other natural disturbances
such as landslides, runoff, clear-cutting. According to Asian Turtle Program published in 2012,
the deforestation, or forest clearance, in Yen Tu Mountain can also lead the reduction of
biodiversity that actions must be done to protect endangered species exist in the area. For all
great cultural and scientific values, Yen Tu is requested by the countrymen of Vietnam to be
identified as a World Heritage Recognition in near future
Summary of Trip
The Halong Bay trip has allowed us to see the incredible talent of Mother Nature in creating such
wonder as Halong Bay for us to visit in just a short amount of time. We have come to witness the
magnificent Karst landscape formed through millions of years, the caves, islands, islets and lakes
scattering over the bay. Travelers’ are gasped to perceive such splendid structure of Cat Ba
Island, Cong Do Island, the beauty of the bay in North Vietnam as well as the grad opulence of
Yen Tu Mounain. Our trip’s goal is to help travelers understand more about nature, its location,
biomes and biodiversity, consequently seek the best way to conserve our natural resources,
especially those that are recognized by UNESCO as a World Natural Heritage Site, and preserve
the well-being of the near-future generation.
