Jun Muay Thai, Lamai — Small Open-Air Camp on Koh Samui (2026)

Overview

Jun Muay Thai is an open-air muay thai training camp in the Maret area behind Lamai Beach, on Koh Samui’s southeast coast, open Monday-Saturday with group classes and closed Sundays. Its own site lists a daily drop-in rate of 300 THB (~8.50 USD) and on-site accommodation across seven room options, which makes it one of the cheapest camps on the island for a visitor who wants to train and sleep in the same compound.

Key facts: Open-air gym in Maret, Lamai · Mon-Sat, morning and evening (16:30-18:30) group classes, closed Sun · Private lessons bookable 09:00-15:30 · Drop-in 300 THB (~8.50 USD), monthly 7,000 THB (~200 USD) · 7 on-site room options, cheap to high end

Facilities and Training

Jun Muay Thai’s own gym page describes “2 full size rings, 14 bags, 11 sit up benches, 7 punch tyres, 2 punch pads and multi purpose jig saw floor mats” laid out under an open-air roof rather than an air-conditioned hall. That is a modest but complete setup for a small camp — two rings is enough to run a group class and a private lesson side by side, and the mat area covers conditioning work beyond bag rounds.

Group classes run Monday to Saturday in a morning session and an evening block from 16:30 to 18:30, with the gym closed on Sundays. Anyone wanting one-on-one coaching can book a private lesson any time between 09:00 and 15:30, which is the same window most group-only camps leave empty. The site does not publish trainer names, fight records or certifications, so first-timers who care about a coach’s competitive background should ask directly at the camp rather than assume a credential the site hasn’t stated.

What It Costs

Jun Muay Thai’s own pricing table, checked 17 September 2026, is unusually direct: “the price quoted above is what you pay, we do not add any hidden fees.”

At 300 THB (~8.50 USD), Jun’s drop-in rate is the lowest of any Koh Samui camp in our comparison table — a direct trade against the smaller, un-air-conditioned facility compared with larger camps like Superpro Samui or Punch It Gym. Our Koh Samui muay thai gyms guide compares Jun Muay Thai against the island’s five other active camps side by side.

Accommodation

Jun Muay Thai offers on-site lodging with, in its own words, “7 room options … ranging from cheap to high end.” The site does not itemise nightly rates or room photos beyond that range, so a trainee choosing between tiers should ask what’s available for their dates before committing to a multi-week stay. On-site accommodation puts training, sleeping and the open-air gym floor in the same short walk, which matters most for anyone doing two sessions a day.

Getting There

Jun Muay Thai sits in Tambon Maret, the subdistrict directly behind Lamai Beach, roughly 30-35 minutes by taxi from Samui International Airport (about 350-450 THB, ~10-13 USD) and 20-25 minutes from Chaweng. Lamai Beach itself is a short ride away.

The gym’s own site gives the Moo 4, Tambon Maret address but no GPS coordinates, and third-party map listings disagree on the exact soi and street number. The coordinates on this page mark an approximate Maret-area centroid, not the gym’s exact doorway — search “Jun Muay Thai” on Google Maps or confirm the soi with the camp directly before riding out on an unfamiliar road.

Nearby

Lamai and Maret give a training trip somewhere to go outside the ring. Wat Lamai, the village temple set back from the beach strip, is a short drive from the camp. Lamai Viewpoint makes a good walk once the legs have recovered rather than straight after a two-session day. Lamai Beach is close enough for a cooldown swim, and our Lamai area guide covers the rest of the strip — food, nightlife and where to stay — for a full day built around training.

BXB Fight Lab, also in the Maret/Lamai area, is the nearest alternative for anyone who wants a proper strength-and-conditioning room alongside Muay Thai. Living Muay Thai on Koh Samui covers the camp culture — the daily rhythm, the family feel of a small gym — that a camp this size runs on, and our guide to Koh Samui’s muay thai trainers is worth reading before picking any camp on credentials alone. If training goes wrong, our hospitals and clinics guide covers where to go and roughly what a consultation costs.

Pros and Cons

The genuine draw is price: 300 THB (~8.50 USD) for a drop-in is the lowest of any camp in our comparison table, and on-site rooms mean training and sleeping share the same compound. The private-lesson window (09:00-15:30) is wide and cheap at 700 THB (~20 USD) an hour, and the no-hidden-fees line on the pricing page is a rare bit of plain talk for the island.

The honest downside: it’s a small, open-air setup with two rings rather than a large air-conditioned facility, the site names no trainers or credentials, and neither a phone number nor exact coordinates are published on the gym’s own pages — a first-time visitor has to do more legwork than at a bigger camp just to confirm where to show up and who’s teaching.
