Named gyms in Thong Sala, Nai Wok and Ban Tai, honest drop-in, weekly and monthly prices in baht, stadium fight nights at Chinnarach and Venom, and how the island's boutique training scene genuinely compares to Koh Samui and Phuket.
Koh Phangan is best known for the Full Moon Party, but the island also has a real, if boutique, Muay Thai training scene built around Thong Sala, nearby Nai Wok, and Ban Tai to the south. It includes the island's original gym with more than 15 years' history and a strong independent review record, two gyms that run their own fight stadiums, and newer wellness-crossover facilities tied to the Sri Thanu yoga and digital-nomad district. This guide covers the named gyms worth knowing, what each offers, honest THB prices, where to catch a real fight night, and how the island genuinely compares to the much larger scenes on Koh Samui and Phuket.
Every gym on the island runs group classes open to complete beginners - stance, pad work and basic strikes at your own pace, with sparring optional. A single trial or drop-in class is the easiest way to see if a gym and trainer suit you before buying a longer pass.
Several gyms bundle unlimited twice-daily training with on-site accommodation into a single weekly or monthly rate - Venom Muay Thai in Ban Tai is the clearest example, with Train & Stay packages from around ฿5,500 a week. This is the standard way long-stay nomads and fitness travellers train on Koh Phangan.
Koh Phangan has genuine fight infrastructure for an island its size: Chinnarach Muay Thai Gym runs its own stadium with weekly high-season fight cards, and Venom Muay Thai stages a monthly fight night on the 28th. Both are open to spectators as well as gym fighters preparing for a bout.
Reflecting the island's Sri Thanu wellness culture, newer facilities like MAA (Martial Arts Academy) pair Muay Thai with ice baths, a juice bar and yoga, while Evolve Muay Thai sits inside the Sri Thanu digital-nomad and yoga district itself - training here leans more lifestyle-and-recovery than hardcore fight camp.
Koh Phangan's first Muay Thai gym, operating for more than 15 years, with group and private classes for all levels plus an on-site fitness gym. It's the most independently verified gym on the island - TripAdvisor rates it 4.8/5 from 82 reviews and ranks it #16 of 72 things to do on Koh Phangan.
Founded in 2011 a short walk from Thong Sala and the beach, Diamond has a large volume of largely positive TripAdvisor reviews on training quality, though some note accommodation cleanliness. It caps drop-in numbers during the December-March high season, so booking ahead helps.
Founded in 2005 by Suchin "Chinnarach" Kanjanasuwan, a two-time featherweight world champion, this gym has its own venue, Chinnarach Stadium on San Jao Road, with weekly fight nights in high season and tickets from ฿800 to ฿2,000.
About 100m from the beach and five minutes from Thong Sala pier, Venom runs Train & Stay packages from roughly ฿5,500 a week (unlimited sessions, twice daily, six days a week) and hosts its own monthly fight night on the 28th, tickets ฿800-1,200.
A modern beachfront facility with ice baths, a juice bar, and classes spanning Muay Thai, kickboxing, boxing, yoga and kids' sessions. A single class with an ice bath runs around ฿2,500, with packages from roughly ฿4,500 to ฿8,500.
Jomhod (Ban Tai) runs beginner-to-fighter programmes, and Evolve (Sri Thanu) sits inside the island's yoga and digital-nomad district. Both are real, operating gyms with less independent review coverage than the island's longer-established names - worth a direct enquiry before booking a longer package.
Indicative 2026 ranges - actual prices vary by gym, season and length of commitment, and several gyms discount packages paid upfront.
| What | Typical price | Notes |
|---|---|---|
| Drop-in single class | ฿300 - 600 | Standard group session at most Thong Sala and Ban Tai gyms |

| Weekly unlimited pass | ฿1,800 - 3,000 | Twice-daily group training for a short stay |
| Train & Stay (weekly, w/ accommodation) | From ~฿5,500 | Venom's bundled training + lodging package |

| Private 1-on-1 trainer (1 hr) | ฿600 - 1,500 | Focused pad and technique work |
| Fight night ticket | ฿800 - 2,000 | Chinnarach Stadium (up to ฿2,000) and Venom's monthly card (฿800-1,200) |
| Starter gear kit | ฿2,000 - 4,500 | Gloves, hand wraps, shorts and a mouthguard |
Koh Phangan's scene is genuinely smaller than its neighbours. The island's most-reviewed gym has 82 TripAdvisor reviews; by comparison, Phuket's largest international camps span thousands of square metres with a dozen or more rings and hundreds of daily visitors in high season, and Koh Samui's Lamai cluster has a far denser concentration of camps. There's also no single public directory of licensed gyms - the World Muaythai Council does not publish one - so the list above is built from each gym's own site and independently verifiable reviews rather than an official registry. If you want an authentic, low-key island base with real fight nights and named, verifiable gyms, Koh Phangan delivers that honestly. If your priority is the scale, competition and coaching depth of Thailand's biggest international camps, Samui or Phuket - covered in their own BAANLYY guides - are the better fit.
For a first class, shorts, a t-shirt and water are enough - most gyms lend gloves and wraps to trial. If you keep training, budget roughly ฿2,000-4,500 for your own gloves, hand wraps, Muay Thai shorts and a mouthguard; Thong Sala has martial-arts and sport shops, and some gyms sell gear on-site. Wai (the palms-together greeting) your trainers, arrive on time, keep your gear clean, and never step over equipment or point your feet at people or the ring's spirit shrine. Train hard but control your power with partners, and thank your pad-holder after rounds - Muay Thai carries real cultural weight on Koh Phangan just as it does everywhere else in Thailand.
It's a genuine but boutique scene, not a heavyweight international hub like Phuket or Koh Samui. The island has several real, well-run gyms - including one with 15+ years' history and a strong TripAdvisor track record - clustered around Thong Sala, Nai Wok and Ban Tai, plus two gyms with their own stadiums for spectator fight nights. If you want an authentic, low-key island training base alongside Koh Phangan's wellness and Full Moon Party culture, it delivers; if you want the scale of Phuket's biggest camps, Samui or Phuket are the better fit.
A drop-in class is roughly ฿300-600, a weekly unlimited pass ฿1,800-3,000 and a monthly unlimited pass around ฿4,000-8,500 depending on the gym. Venom's Train & Stay weekly package (training plus accommodation) starts near ฿5,500. Private trainers run about ฿600-1,500 an hour, and fight-night tickets at Chinnarach Stadium or Venom's monthly card cost ฿800-2,000.
Most are clustered around Thong Sala, the island's main town - including Phangan Muay Thai & Fitness Gym, Diamond Muay Thai in nearby Nai Wok, and Chinnarach Muay Thai Gym with its own stadium. Ban Tai to the south has Venom Muay Thai and Jomhod Muay Thai Gym, while Evolve Muay Thai sits in Sri Thanu, the island's yoga and digital-nomad district.
Yes. Chinnarach Muay Thai Gym runs its own venue, Chinnarach Stadium, with weekly fight cards in high season, and Venom Muay Thai hosts a monthly fight night on the 28th. Both are open to spectators as well as gym fighters, with tickets roughly ฿800-2,000.
Yes - every gym on this list welcomes first-timers with beginner-friendly group classes covering stance, basic strikes and pad work, and sparring is optional. A single trial or drop-in class, often free or discounted, is the best way to find a gym and trainer that suits you.
For casual training on a tourist visa or visa exemption there's no special requirement. For serious long-term training, some larger, licensed camps elsewhere in Thailand can sponsor a Muay Thai Education (ED) visa - confirm directly with the gym and Thai Immigration whether that's available on Koh Phangan specifically, as licensing and rules change.
