The sound stops you mid-step. It begins as a low whoop, building in intensity until it becomes a full-throated, melodic aria that echoes through the ancient trees. For a moment, you forget you’re in Phuket—Thailand’s most developed island, synonymous with bustling beaches and vibrant nightlife. Yet here, in the island’s last remaining virgin rainforest, the gibbons are singing, and their song carries a message of hope, resilience, and second chances.
Welcome to the Gibbon Rehabilitation Project (GRP)—a sanctuary that doesn’t just rescue endangered primates but works tirelessly to undo the damage caused by decades of exploitation in the tourism industry. This isn’t a zoo, a photo opportunity, or an interactive experience. It’s something far more valuable: a genuine conservation effort where your visit directly supports the painstaking work of returning captive gibbons to the wild.
The Story Behind the Project: Giving Voices Back to the Forest
Founded in 1992 through collaboration between Thailand’s Royal Forest Department, the Wild Animal Rescue Foundation (WARF), and international volunteers, the Gibbon Rehabilitation Project was born from a grim reality . At that time, wild gibbon populations in Phuket had been hunted to extinction—poached to supply a lucrative trade in baby gibbons used as tourist photo props on Bangla Road and elsewhere . For every infant gibbon successfully captured, an estimated seven family members were killed protecting it .
The math is devastating: gibbons are highly territorial, living in small family groups. To steal a baby, poachers must eliminate the parents and often siblings who try to defend the infant. The result? Entire family lines wiped out for a single photo opportunity.
Over three decades later, the project has rescued approximately 400 gibbons and successfully released more than 100 back into protected forests in Phuket and Chiang Mai . Today, thanks to these efforts, a small but self-sustaining population of white-handed gibbons (Hylobates lar) once again swings through Phuket’s canopy—a testament to what dedicated conservation can achieve.
Where Hope Finds a Home: Location and Setting
The Gibbon Rehabilitation Project sits within the Khao Phra Thaeo National Park, Phuket’s last remaining untouched rainforest . This 23-square-kilometer protected area in Thalang District represents the island’s ecological heart—a lush expanse of virgin jungle that provides the only suitable habitat for wild gibbons in the region .
The center is located near Bang Pae Waterfall, creating a natural pairing for visitors: a morning of learning about conservation followed by a refreshing dip in the falls . The setting itself reinforces the project’s mission—you’re not in a sterile facility but on the edge of the very forest where rehabilitated gibbons will eventually make their homes.
One visitor described the experience: “The project is located in a more remote part of Phuket and the last remaining rainforest on the island. As others have said, this definitely isn’t a zoo but it’s an incredible place where they’re doing vital work” .
Understanding the Mission: More Than a Sanctuary
What makes the Gibbon Rehabilitation Project genuinely ethical—and distinguishes it from countless animal attractions across Thailand—is its unwavering focus on release rather than display. The mission isn’t to create a permanent collection of gibbons for public viewing. It’s to prepare rescued animals for return to the wild, where they belong.
This mission drives every decision, from facility design to visitor policies:
The “Golden Rule”: Once a gibbon enters the rehabilitation zone, staff never touch them again . This minimizes human attachment—crucial for animals that must learn to fear humans to survive in the wild. Visitors, likewise, maintain strict distance.
The Rehabilitation Process: Rescued gibbons undergo quarantine and health screening before entering the rehabilitation center. Here, staff employ ingenious techniques to “teach gibbons how to be wild again”—placing obstacles on enclosure floors to encourage swinging rather than walking, using camouflage screens to reduce human visibility, and operating rope-based feeding systems that minimize contact .
The Pairing Puzzle: Gibbons are monogamous and live in family groups. Releasing a single gibbon is, as project head Thanaphat Payakkaporn puts it, “like going to a bar alone” . Lone males particularly risk aggression toward other males in the wild. The project builds “love tunnels” between enclosures, allowing potential pairs to meet while maintaining their own space. Only after pairs mate and produce offspring can a family be considered for release .
Release and Monitoring: When a family is ready, they’re translocated to a release site within their historical range. A team stays for at least two months, monitoring adaptation, introducing wild foods, and steering them away from danger or human settlements . It’s intensive, expensive, and emotionally demanding work.
What Visiting Actually Looks Like
If you’re expecting a typical animal attraction where you can get close, take selfies, or interact directly, this isn’t the place for you. And that’s precisely the point.
Booking and Access
Visits are available only through pre-booked learning sessions—the project is otherwise closed to ensure minimal disturbance to the gibbons . Tours run multiple times daily, with sessions at approximately 10:30 AM, 12:30 PM, and 2:00 PM .
One recent visitor shared: “We were there for an hour show at 9:15 in the morning. It was only us who had booked the ticket, so we had a very personal experience. However, they only enclose a limited number of people into the day” .
Booking in advance is strongly recommended, especially during peak season . You can book through their website or contact them via WhatsApp—a modern touch for a conservation project .
What to Expect During Your Visit
The Learning Session: You’ll gather with a small group and a guide—often a long-term volunteer or staff member with deep knowledge of individual gibbons. Guides like Roch receive consistent praise: “Our guide Roch was absolutely outstanding! He has been working for the project for many years and was so passionate and knowledgeable about the Gibbons – I learned so much and it was fascinating!”
Observation, Not Interaction: You’ll walk through the forested area, observing gibbons in their enclosures from a respectful distance. The project maintains strict “no-touch” policies, and visitors must stay at least 2 feet away at all times . This isn’t about getting close—it’s about understanding.
Learning the Stories: What makes the experience powerful is hearing individual gibbons’ histories. Bo, a 37-year-old resident, was rescued in 1993 after five years as a pet. Despite seven release attempts, he keeps returning to the center or seeking out humans—a permanent resident now, living evidence of how deeply captivity can mark a wild creature . His son, born after Bo’s arrival, was successfully released and occasionally visits, his songs echoing through the forest where his father can hear .
The Surrounding Forest: The project’s location within Khao Phra Thaeo means you’re immersed in Phuket’s last rainforest. One visitor noted: “Fascinating to hear the Gibbon monkeys talk to the wild monkeys in the surrounding rainforest” . That dialogue—between rehabilitated gibbons and their wild-born offspring—represents the project’s ultimate success.
Practical Information
Cost: Entry requires both a project tour fee (approximately 1,000 baht) and the national park entrance fee (approximately 200-400 baht, depending on recent updates) . Note that prices may vary, so check current rates when booking.
Duration: Learning sessions run approximately 1-1.5 hours, with some extended options available .
What to Bring: Comfortable walking shoes, insect repellent (essential in the rainforest), water, and swimwear if you plan to visit Bang Pae Waterfall afterward .
Getting There: The project is in a remote area with no public transportation options . You’ll need to arrange a taxi, Grab (ride-hailing app), or private transfer. Consider negotiating a round-trip fare with your driver to ensure return transport.
Best Time to Visit: Morning sessions are ideal—gibbons are most active, and you’ll beat the afternoon heat . Weekdays see fewer crowds than weekends .
Why “No Interaction” Is the Most Ethical Choice
In an age where tourists increasingly seek “experiences”—elephant rides, tiger selfies, dolphin shows—the Gibbon Rehabilitation Project stands apart by deliberately limiting what visitors can do. This isn’t an oversight or lack of resources. It’s a conscious, scientifically-grounded approach to animal welfare.
The project adheres to IUCN best practice guidelines for gibbon rehabilitation, which emphasize minimizing human contact to increase release success rates . Every policy—from rope feeding systems to restricted visiting hours—serves the gibbons’ ultimate return to the wild.
This commitment extends to refusing photo opportunities with gibbons, despite the revenue such interactions would generate. As the project’s head explains, the emotional toll of failed releases weighs heavily: “Gibbons are my brothers. Whenever I failed and they died, I felt I was responsible for my brother’s death” .
For ethical travelers, this approach represents gold-standard practice. One visitor captured it perfectly: “This tour excelled our expectations. You won’t get close to the gibbons as it’s the centre’s mission to minimise contact with humans to hopefully return the gibbons to the wild in the future. The gibbons that we observed were the ones that are furthest from being ready for release” .
The Numbers: Measuring Success and Challenge
Quantifying success in wildlife rehabilitation is complex. The project’s early years saw high mortality rates as techniques were developed through trial and error. Between 2002 and 2012, 30 gibbons were released in Phuket, with 11 born in the wild. Of these 41 individuals, 18 died, disappeared, were poached, or returned to the center .
These numbers might seem discouraging until you consider the alternative: certain death in the illegal pet trade or tourism industry. Today, the project estimates at least 66 gibbons have been successfully released or born in the wild in Phuket since 2002, with multiple generations now present . In Chiang Mai, at least 30 have been released since 2014 .
A 2015 study in the Natural History Bulletin of the Siam Society praised the GRP as the “only reasonably successful attempt so far” to release gibbons in Asia . While cautioning against expecting such projects to solve broader conservation challenges, researchers acknowledge the GRP has successfully reintroduced gibbon populations and restored forest ecosystems in a small portion of their historical range .
Beyond the Gibbons: Combining Your Visit with Nature
One of the project’s advantages is its location within Khao Phra Thaeo National Park, allowing visitors to combine their conservation experience with genuine rainforest exploration.
Bang Pae Waterfall: Just a short walk from the Gibbon Rehabilitation Project, this waterfall offers a refreshing swimming hole perfect for cooling off after your tour . Multiple visitors recommend combining the experiences: “After the visit we then hiked up the adjacent river to the nearby Bang Pae waterfall for a cooling dip!”
Ton Sai Waterfall: Another waterfall within the park, accessible via hiking trails through pristine forest .
Wildlife Spotting: The park is home to langurs, wild boars, mouse deer, and diverse bird species . Early morning visits increase your chances of sightings.
Hiking Trails: Several trails wind through the protected forest, offering opportunities for deeper immersion in Phuket’s natural heritage .
A Note on Recent Developments: Combined Conservation Tours
The project’s reputation has grown significantly in recent years. In 2024, a shore excursion combining the Gibbon Rehabilitation Project with the Sireetarn Marine Endangered Animals Rescue Centre launched, offering cruise passengers a comprehensive conservation experience . This tour was shortlisted for Best Excursion at the 2025 Wave Awards, demonstrating that ethical, educational wildlife tourism can succeed commercially .
The tour includes beach clean-ups, educational sessions with marine biologists, and the same limited-contact gibbon observation available to independent visitors . It’s available through Norwegian Cruise Line and other operators, priced around $139 USD per person .
For independent travelers, however, booking directly through the project ensures your contribution goes directly to gibbon care rather than third-party operators.
Supporting the Mission Beyond Your Visit
If your visit inspires you to do more—and it likely will—several options exist:
Sponsor a Gibbon: For approximately $60 USD, you can sponsor a gibbon’s care, receiving updates and a certificate . This ongoing support helps cover the significant costs of rehabilitation, which includes veterinary care, specialized diets, and enclosure maintenance.
Donate Directly: The project relies on visitor income and donations, receiving no state subsidies . Every baht counts.
Purchase Merchandise: The on-site gift shop sells educational materials and souvenirs, with proceeds supporting operations . Past initiatives have included volunteer-designed t-shirts raising 35,000 baht for the Wild Animal Rescue Foundation .
Spread the Word: Perhaps most importantly, share what you’ve learned. The illegal wildlife trade persists partly because tourists remain unaware of the suffering behind photo opportunities. Your understanding can influence others’ choices.

Conclusion: The Song Continues
The Gibbon Rehabilitation Project offers something rare in Thailand’s tourism landscape: an animal experience where the animals’ welfare genuinely comes first. You won’t get a selfie with a gibbon on your shoulder. You won’t watch them perform tricks. What you will gain is understanding—of the devastating impact of wildlife trafficking, the painstaking work of rehabilitation, and the resilience of creatures given a second chance.
And if you’re lucky, you’ll hear them sing.
That morning when Bo’s son calls from the wild forest, his song drifting back to the center where his father listens, you’ll understand what all the effort means. Not just for these individual gibbons, but for the species, for the forest, for the possibility of restoration in a world that often seems beyond repair.
As one visitor concluded: “If you’re looking to visit/support a more ethical environmental organisation whilst in Phuket I highly recommend a visit to the Gibbon Rehabilitation Project to see and learn about these amazing animals” .
The gibbons of Phuket were silenced once—hunted to extinction in the wild by an industry that valued them as props. Today, their songs again echo through the island’s last rainforest. And with every visitor who chooses understanding over interaction, education over exploitation, that chorus grows stronger.
Plan your visit, listen carefully, and leave knowing you’ve helped ensure the song continues.
