7 Best CrossFit Boxes in Koh Samui, Thailand

Where the gyms are

The gyms sit in three pockets of the island. Pick the one closest to your hotel, because taxis add up.

• North (Bophut and Mae Nam): Koh Samui CrossFit in Bo Phut, Superpro Samui in Bophut and FITKOH in Mae Nam.
• South (Lamai): Koh Fit Thailand, Samui Fitness Lab and Lamai Fitness Retreat. Lamai Fitness Retreat is 25 minutes by taxi from Koh Samui Airport (USM).
• West (Taling Ngam): Gravity Movement Gym, 10 minutes by car from Lipa Noi beach.

What a drop-in costs

Drop-ins run from 450 to 650 THB. The median is 500 THB.

What the drop-in buys differs by gym:

• Gravity Movement Gym: the 450 THB day pass includes gym access and one group class.
• Koh Fit Thailand: 450 THB buys one HYROX class. A gym day pass is 900 THB and adds the pool, towel rental and 90 minutes in the onsen spa.
• Superpro Samui: 500 THB for a class, 400 THB for the indoor gym.
• Samui Fitness Lab: 600 THB for a class or staffed open gym. An all-access day pass with 24/7 gym entry is 750 THB.
• Koh Samui CrossFit: 650 THB for a class and 500 THB for open gym. Book drop-ins through Mindbody.

Lamai Fitness Retreat and FITKOH sell multi-day camp packages, not casual drop-ins. Lamai Fitness Retreat packages start at 17,000 THB per week and include private accommodation and unlimited classes.

Gravity Movement Gym keeps classes small, so book online ahead. Koh Fit Thailand caps daily admissions, so book ahead there too. Samui Fitness Lab lets you book online or walk in 15 minutes before class.

Heat and climate

Four gyms have air conditioning: Gravity Movement Gym, Koh Fit Thailand, Superpro Samui and Samui Fitness Lab. Each also has open-air zones.

Two gyms train in the open air. Koh Samui CrossFit uses fans on an open floor. Lamai Fitness Retreat is outdoors.

Plan around the heat:

• Book the early sessions. Koh Samui CrossFit opens at 7:00 AM on weekdays, and Samui Fitness Lab runs a 7:30 class.
• Superpro Samui runs HYROX at 8:00 and 17:00 on weekdays, which gives you a cooler evening option.
• Samui Fitness Lab also has a separate 24/7 air-conditioned gym for lifting at any hour.

Rebrands and closures

• Koh Samui CrossFit trades as Koh Samui Training Camp. It is the official affiliate in Bophut, and it has been one since June 2023.
• KS CrossFit is closed. Its listing shares the address 48/10 Moo 3 with Superpro Samui, the dedicated HYROX club.
• crossfitsamui.com is an old domain reportedly parked for resale. It has no link to the current Bophut affiliate.
• Lamai Beach CrossFit shows no activity after 2020.
