Herping in Hon Son Island: Vietnam’s Best-Kept Secret for Wildlife Enthusiasts
When most travelers think of Vietnam’s tropical islands, pristine beaches and seafood are usually the first things that come to mind. However, tucked away in the Gulf of Thailand lies Hon Son Island, an untouched paradise that offers something even more exciting for wildlife lovers—herping.
For reptile enthusiasts, photographers, biologists, and adventurous travelers, Hon Son is one of the most fascinating destinations in southern Vietnam. Despite its relatively small size, the island is home to several endemic reptiles found nowhere else on Earth, alongside an impressive diversity of snakes, frogs, geckos, spiders, and other nocturnal creatures.
Whether you’re an experienced herper or simply curious about tropical biodiversity, a guided herping expedition on Hon Son Island promises unforgettable encounters with some of Southeast Asia’s most remarkable wildlife.
Where is Hon Son Island?
Hon Son Island (Hòn Sơn) belongs to An Giang (Previous name Kien Giang) Province, located approximately 65 km off the coast of Rach Gia City. Unlike the more famous Phu Quoc Island, Hon Son has remained largely untouched by mass tourism.
The island features:
- Dense tropical rainforest
- Granite mountains
- Coastal forests
- Rocky streams
- Fishing villages
- Crystal-clear coral reefs
Its varied habitats create the perfect environment for reptiles and amphibians, making it one of Vietnam’s most rewarding destinations for wildlife observation.
During the rainy season (May to November), the forests come alive after sunset, revealing an extraordinary diversity of nocturnal animals.
Why Hon Son is a Herping Paradise
Herping—the search for reptiles and amphibians in their natural habitat—is becoming increasingly popular among European wildlife travelers.
Unlike traditional sightseeing tours, herping offers the thrill of discovering secretive animals that most visitors never notice.
Every night in the rainforest is different.
Within only a few hours of hiking, you may encounter:
- Hon Son pit vipers
- Golden tree snakes
- Vine snake
- Wolf snakes
- Colorful frogs
- Bent toe geckos
- Tarantulas
- Tailless Whip spiders
- Forest scorpions
The excitement comes from never knowing what you’ll find around the next corner.
Meet the Endemic Species of Hon Son Island
One of the biggest reasons wildlife enthusiasts visit Hon Son is its remarkable endemic reptiles.
Trimeresurus honsonensis – Hon Son Pit Viper
Discovered only recently, Trimeresurus honsonensis is one of Vietnam’s newest pit viper species.
This beautiful green viper is endemic to Hon Son Island, meaning it exists nowhere else on Earth.
Characteristics:
- A subdued dull yellow to light brown or grey-brown.Heat-sensing facial pits
- Nocturnal ambush predator
- Usually found resting on shrubs or low tree branches
- Venomous but generally shy
Spotting this species in the wild is often considered the highlight of any herping expedition.
Cyrtodactylus borgattaorum – Borgatta’s Bent-toed Gecko
Another endemic treasure is Cyrtodactylus borgattaorum.
This beautifully patterned gecko inhabits granite boulders and humid forest environments.
Like many bent-toed geckos, it becomes active shortly after sunset and is often found climbing rocks covered in moss.
Its camouflage makes it surprisingly difficult to detect, even for experienced herpers.
Cyrtodactylus eisenmanae – Eisenman’s Bent-toed Gecko
Hon Son is also home to Cyrtodactylus eisenmanae, another endemic bent-toed gecko.
Although similar in appearance to other Cyrtodactylus species, careful observation reveals unique patterns and body proportions that distinguish it.
Finding both endemic geckos during one evening is an unforgettable experience for reptile photographers.
Other Amazing Wildlife You May Encounter
Hon Son’s biodiversity extends far beyond its endemic reptiles.
Some of the most frequently observed species include:
Oriental Whipsnake (Ahaetulla prasina)
A stunning bright-green arboreal snake with excellent camouflage and remarkable eyesight.
Despite its intimidating appearance, it is mildly venomous and harmless to humans.
Common Wolf Snake (Lycodon capucinus)
Often mistaken for juvenile kraits, this non-venomous species frequently appears around villages and forest edges at night.
Its bold black-and-white pattern makes it a favorite among photographers.
Vietnamese Bug-eyed Frog (Theloderma vietnamense)
One of Vietnam’s most beautiful tree frogs.
Its rough, moss-like skin provides perfect camouflage among wet tree trunks.
Tailless Whip Spider (Phrynichus orientalis)
Although often mistaken for a spider, this fascinating arachnid is completely harmless.
Its incredibly long sensory legs allow it to navigate through complete darkness.
It is one of the most exciting nocturnal invertebrates to photograph.

Depending on weather conditions and season, visitors may also observe:
Golden tree snake, Flying geckos, Sun Skinks, Tokay gecko, Forest centipedes, Giant millipedes, Orb-weaver spiders, Hermit spider, Tarantulas, Huntman spiker, Kapok bug… Every outing offers different surprises.
