Prices in THB were confirmed with the camp on 30 July 2026. EUR is approximate at roughly 38 baht to the euro and the exact rate moves daily. The camp refurbished its rooms over late 2025 and early 2026 and its own website has not caught up, so these accommodation rates and room types are newer than the ones published there. Confirm before booking.

About the camp

Why people come, what it's like, what it isn't.

Diamond has been running in Nai Wok on Koh Phangan since 2011, and the shape of the place has barely changed in that time. Everything sits on one site: two rings under a thatched roof, a long row of bags, the bungalows, and the tables where everyone eats after training. For a solo traveller that matters more than it sounds. You do not arrange anything, you do not go looking for anyone, and by the end of your first day you have eaten two meals with the same group of people.

This is a train and stay camp built around Western visitors, and it is worth being straight about that from the start. You are not going to be sharing the floor with a stable of Thai fighters preparing for Bangkok. The trainers have that background, several of them at a high level, but the students around you will almost all be travellers. The row of national flags strung across the training floor is an accurate summary of the room.

Sessions run twice a day, Monday to Saturday, and the structure is the same each time. Fifteen minutes of skipping, then stretching together. Hand wraps go on, and the trainers do them for you until you can manage it yourself. Then shadow boxing, with the group split into beginners and more experienced. From there it is pads one on one with a trainer, or freestyle work on the heavy bag while you wait your turn. Three rounds on the pads when it is quiet, and two rounds when the session is busy, which it often is. Shin guards on for three rounds of sparring, then strength and conditioning. The cool down is the detail worth knowing: everyone stands in a circle and takes a turn leading a stretch, so the group works through a different exercise each time round and everyone has said something to everyone before the session ends. Food is on the table before you have caught your breath.

The private sessions are the thing to book. The best hour of one on one coaching I have had anywhere in Thailand was here, and the reason is not only the coaching. It is that the hour is an actual hour. At a lot of gyms a sixty minute private turns into thirty or forty minutes of work once you take out the warm up, the trainer resting between rounds, and a long cool down at the end. That did not happen. I ran for twenty minutes beforehand so the clock would not be spent on a warm up, and got sixty minutes of undivided attention on two things: balance through combinations, and the mechanics of throwing an elbow. I train at an advanced level, and those two adjustments moved me further in an hour than the group sessions would have in a fortnight. At 700 baht that is the best value on the price list by a distance.

The honest trade-off: the group class is pitched at a mixed room, and the pad rounds are the thing to watch. Two rounds instead of three is a meaningful difference over a month, and the busier the season the more often that happens. The camp caps drop-in numbers from December to March for exactly this reason, which tells you they know. The other thing is the food. Two meals a day are included and they are served hot straight after training, but it is rice, curry and a boiled egg with some fruit, and it is not enough to live on. Budget for eating out or at the 7-Eleven on top of your package. Neither of these makes Diamond a bad camp. They make it a specific one. If you want a hard, quiet fight camp with Thai training partners, the mainland will serve you better. If you want to arrive alone, be looked after, and buy a few privates to actually improve, this is a very good choice.

A typical day

Roughly what a balanced training day looks like. First-week visitors typically do only one of the two main sessions while the body adjusts.

08:00
Morning session starts
Fifteen minutes of skipping, then stretching together as a group. Trainers wrap your hands for you until you can do it yourself.
08:20
Shadow boxing
The group splits into beginner and advanced before this point, so you work at your own level.
08:40
Pads or heavy bag
One on one pad rounds with a trainer, usually two rounds and three when it is quiet. Everyone not on pads works freestyle on the heavy bag.
09:15
Sparring
Shin guards on, three rounds.
09:40
Strength and conditioning
Conditioning work before the session winds down.
09:50
Cool down in a circle
Everyone stands in a ring and takes a turn leading one stretch, so the whole group works through a different exercise each time round. A small thing that does a lot for how the place feels.
10:00
Food, together
Rice, curry and a boiled egg, plus fruit, served straight after training and eaten as a group. Plan on buying most of your food elsewhere.
16:00
Afternoon session
Same structure as the morning. Monday to Saturday.

What guests say

Recurring themes from traveler reviews, summarized in our words.

✓ Trainers give a lot of one on one time The dominant theme
Visitor after visitor describes a high number of trainers on the floor and genuine individual correction, including people doing their first ever session. Several mention being taken aside as a group of newcomers to work on form.
✓ Unusually strong social scene Mentioned in almost every review
Eating together after every session is the thing people remember. Group trips, a student WhatsApp group and a steady turnover of solo travellers make it easy to arrive alone and not stay that way.
✓ A gentle place to start Common among first timers
The beginner and advanced split, plus trainers who wrap your hands for you, come up repeatedly from people who had never trained before arriving.
✓ Female solo travellers report feeling comfortable Recurring
Several accounts from women travelling alone describe the camp and the surrounding area as easy to navigate, and mention female students training regularly.
× Almost entirely Western students The honest trade-off
This is not a camp where you train alongside a stable of Thai fighters. Reviewers comparing it with mainland gyms consistently note the difference in intensity and in who is on the floor. If that is what you came for, look at the mainland.
× Room cleanliness came up repeatedly Frequent before the 2025 refurbishment
Cleanliness of the accommodation was the most common complaint in older reviews. The camp refurbished the rooms over late 2025 and early 2026, so this may no longer hold. Worth checking on arrival.
× The included food is not enough to live on Consistent across sources
Two meals a day are served after training, typically rice, curry and an egg with fruit. Reviewers and our own visit agree you will be buying food elsewhere on top, and many prefer the local markets anyway.
× It gets busy, and pad rounds get shorter December to March especially
The camp limits drop-ins in high season for this reason. In practice a busy session can mean two rounds on the pads instead of three.

Is this camp right for you?

Honest signals — we'd rather you pick a different camp than be disappointed.

✓ Best for

  • Complete beginners. Trainers wrap your hands until you can, and the group splits by level
  • Solo travellers who want a ready made social group from day one
  • Anyone who wants training, food and a room on one site with nothing to arrange
  • Combining training with island life rather than shutting yourself away
  • Anyone willing to buy a few privates. The one on one coaching is the strongest thing this camp offers and it is not what the group class is built for
  • Anyone who wants to take a fight without a long wait. The camp arranges bouts from a relatively low level

× Not for

  • Anyone who wants to train alongside a stable of Thai fighters. The floor here is almost entirely Western students, and the mainland camps will serve that better
  • People who expect the group class alone to move them forward quickly. Sessions are pitched at a mixed room, and in high season pad rounds drop from three to two
  • Anyone expecting the included meals to cover their eating

Practical details

The stuff you'd otherwise have to email about.

Getting there
Two routes from Bangkok. Fly to Koh Samui (USM), take the thirty minute ferry across to Koh Phangan, and walk from the Koh Phangan pier to the camp in ten to fifteen minutes. No transfer to arrange at all. The cheaper route is to fly to Surat Thani (URT), where flights from Bangkok cost less, but the ferry crossing is considerably longer.
Minimum stay
None. Single sessions are possible at 400 THB, or 300 THB the first time. Most people stay one to two weeks. Rooms are a different matter: book weeks and preferably months ahead, because the camp fills. In August, which is low season, it was already well attended.
🏠
Accommodation
On site. The camp refurbished its rooms over late 2025 and early 2026, so the only fan cooled option now is the single occupancy bamboo bungalow, at 7,000 THB a week or 24,000 a month all inclusive. Air con options run from a single bamboo bungalow with ensuite at 9,000 a week, through a shared deluxe twin at 7,500 per person, to a deluxe single at 10,000. Air con rates include electricity. Rooms are held with a deposit by Wise transfer and the camp says they book up fast. Check in from 15:00, check out by 11:00.
🥊
Fight arrangement
Yes, and from a lower level than at most camps. People who had been training one to two months were getting in the ring during our visit. Tell the camp if fighting is a goal.
📝
Visa
Checked August 2026. Diamond does not sponsor training visas. Most visitors arrive under Thailand's visa exemption scheme, which is currently in transition: the 60 day exemption introduced in 2024 is being replaced by a shorter one, and the change takes effect only after publication in the Royal Gazette. We deliberately do not quote a number of days here because it would go out of date. Check with the Thai embassy or consulate for your own nationality shortly before you travel, and plan around what you are actually granted on arrival.
🥋
Gear
Gloves, shin guards and wraps can be borrowed for every session at no charge. There is also a shop on site selling gear. If borrowing shin guards does not appeal, sock style shin guards are a good compromise and pack far better than full size ones, which are awkward in a suitcase.

Common questions

Asked by previous visitors. Click to expand.

Is Diamond good for complete beginners?
Yes, this is what it does best. The group splits into beginner and advanced before the main work starts, trainers wrap your hands for you until you learn, and a large share of any session is people training for the first time. Gloves, shin guards and wraps can all be borrowed, so you can turn up with nothing.
Is Diamond a good fight camp?
It depends what you mean. If you want a bout, the camp arranges them and from a lower level than most: people training one to two months were getting in the ring during our visit. If you mean a quiet camp where you train alongside Thai fighters preparing for Bangkok, no, and the mainland will serve you better.
What does a month cost?
Training only is 7,000 THB a month for 24 sessions, or 10,000 THB for 48. Train and Stay, which includes a room, two meals a day, yoga, conditioning classes and gym access, runs from 24,000 THB a month for a fan cooled bamboo bungalow up to 40,000 THB for a deluxe suite. A month means 28 nights.
Are the included meals enough?
No, and it is worth planning for. Two meals are served straight after training, typically rice, curry and a boiled egg with fruit alongside. You will want to buy food elsewhere on top, and the local markets are cheap and good.
How far ahead should I book a room?
Weeks, and preferably months. In August, which is low season, the camp was already well attended, and high season fills it properly. Rooms are held with a deposit by Wise transfer.
What if the rooms are full?
Rent an apartment nearby and take a training only package. Nai Wok is walkable and Koh Phangan is a good place to be based, so this is a real alternative rather than a consolation. It also works out cheaper if you do not want two meals a day.
How do I get there from Bangkok?
Fly to Koh Samui, take the thirty minute ferry across to Koh Phangan, and walk from the Koh Phangan pier to the camp in ten to fifteen minutes. Nothing to arrange. The cheaper option is to fly to Surat Thani instead, where flights from Bangkok cost less, but the ferry crossing is a lot longer.
Is there a minimum stay?
No. You can drop in for a single session at 400 THB, or 300 THB the first time. Most people stay one to two weeks. Note that the camp caps drop-in numbers between December and March.
What gear do I need?
None to start with. Gloves, shin guards and wraps are there to borrow for every session, and there is a shop on site if you would rather buy your own. Sock style shin guards are worth considering: they pack far better than full size ones and solve the hygiene question.
Do I need a visa?
Diamond does not sponsor training visas. Most visitors arrive under Thailand's visa exemption scheme, which is currently in transition: the 60 day exemption introduced in 2024 is being replaced by a shorter one, and the change takes effect only after publication in the Royal Gazette. Because of that we do not quote a number of days here. Check the Thai embassy or consulate for your own nationality shortly before you travel, and plan your booking around what you are actually granted on arrival rather than what you expect.
When is the best time to come?
The islands run a reverse monsoon compared with Phuket. December to April is driest and also busiest, and October and November are the wettest months. May to September is a good window, quieter and still very trainable.
Are the private lessons worth it?
In our experience yes, and for a specific reason. The hour is an actual hour of work. At a lot of gyms a sixty minute private quietly becomes thirty or forty minutes once you subtract the warm up, the trainer resting between rounds and a long cool down. That did not happen here. Warm up on your own beforehand and you get the full hour on technique. A private is 700 THB, or 2,500 THB with Kru Santos.
Can an advanced student still get something out of it?
Yes. On our visit a single hour of private work on balance through combinations and on elbow mechanics produced a bigger change than weeks of group class would have. Group sessions are pitched at a mixed room, so if you already train seriously, budget for privates rather than expecting the group class to do it.
