Koh Mak makes a great base for diving as the marine Park of Koh Rang, just to the west of the island, sits on its doorstep.
Some of the best sites in the Koh Chang Islands are found there and due to Koh Mak’s close proximity, less diesel is required to get there, so prices can be held cheaper. Getting to Koh Rang and returning is also much quicker, so you can enjoy a couple of leisurely dives and still have most of the afternoon back on the beach.
Further away but very much on the radar, the HTMS Chang, the largest wreck in Thailand, and its new companion, the T11 makes for exciting wreck diving options.
There are currently two dive shops on Koh Mak, with prices broadly similar across the board. Deals are to be had for multiple days of diving when booked together. Transfer to and from your resort and lunch are included in the price.

Snorkeling off Koh Mak
The dive boats and other companies offer days out snorkeling at the Koh Rang Marine Park for around 750bt to 950bt. Typically, you will visit 3 or 4 of the tiny islands and one of the beaches, with transfer to and from your resort, as well as equipment and lunch all included.
Around Koh Mak, several of the resorts have their own boats and daily local trips are also possible, together with speedboat tours around the offshore islands. Cococape Resort, itself at the very southern end of Ao Suan Yai, goes out near its pier, as well as around the cape to Ao Pra, the next bay along, and then over to the tiny island of Koh Pii, which lies at that bay’s top end.
Prices for these days depend on numbers and how many hours, but 1000bt for a half day seems the norm. Private charters which go further afield or the whole day start at 5,000bt and would include most of the larger offshore islands such as Koh Kradat, Koh Kham, Koh Rayang Nok and its neighbour, Koh Rayang Nai, with their entrance fees if applicable included.

Koh Mak Sailing, Windsurfing and Kayaking
Sailing is now available on Koh Mak, with two different size of Hobie Catamaran available for hire at 1,000bt to 1,500bt an hour. Ask at Holiday Beach Resort, Koh Mak Resort, Ao Kao Resort or Baan Koh Mak. Windsurfers can be rented at 1,200bt a day, 800bt a 1/2 day or for 1.5 hour lesson, also at 800bt from the same spots.
Kayaks cost around 100bt an hour, 300bt a half day and 500bt for the day and they are an excellent way of exploring the coastline, visiting the offshore islands and seeking out some of the tucked away and deserted beaches. Where you can reach will depend on your stamina, but from Ao Suan Yai (Koh Mak Resort), it is a very gentle paddle across to Koh Kham and not so very far to the excellent snorkeling around Koh Pii and off Ao Pra. Requiring more effort in the other direction is the lovely and utterly deserted beach at Ao Tao Kai (Turtle Beach), which lies in the very north of the island.
On Ao Kao in the south west, it will take about 30 to 45 minutes to Koh Rayang Nok. Holiday Beach Resort at the far end of Ao Kao (Ao Kra Tueng) is a good place to rent kayaks, as well as offering its own private snorkel trips.
