Koh Mak measures 16 square kms in total, with a width of 10 kms and length of 5 kms from north to south. It is suitable for families as the island is devoid of loud bars and late night partying. Most of the areas are either walking or cycling distance away, making the island suitable for mountain bike explorers. There is a concretely paved road system that covers most of the central and western side of the island. There are songthaews that stop on specified areas on the island that charge THB 50/person regardless to which point you will get off. Other than that, one can rent motorbikes to explore the island.
Basically, there are two main beaches on Koh Mak: Suanyai beach on the northwest, or Ao Khao Beach
on the northern part of the island.
- Ao Khao Beach is the most developed part of the island and the busiest of all the beaches, relatively, as Koh Mak’s beaches never seem to get filled up. Running parallel to the beach are a number of resorts, and small restaurants.
- Ao Suanyai Beach is made up of 2 kms stretch of white sandy beach. Here you will find Koh Mak Resort
- Ao Katueng Beach is a long stretch of sand on the southwest part of the island. Here you will find Makathanee Resort
- Ao Phra Beach is a shallow beach with dark, volcanic rocks that separate it from Suanyai Beach.
- Ao Taan Beach is more mangroves than sandy beach. The sand is not very white and not very suitable for swimming. In close proximity is Ao Pai where you will find Plubpla Koh Mak Retreat
Koh Mak is a sub-district to Koh Kood and is actually comprised of 9 islands: Koh Mak, Koh Rayang Nai, Koh Rayang Nok, Koh Phi, Koh Kham, Koh Kradad, Koh Nook, Koh Nok and Koh Nai.
- Koh Rayang Nai and Koh Rayang Nok are off the western end of Ao Khao and can be reached by a longtail boat that leaves from Makathanee Resort. Koh Rayang Nai is a privately owned island which serves as a family heirloom handed from one generation to the next. During low tide, tourists can wade from Koh Mak to Koh Rayang Nai for snorkeling, fishing and squid fishing. Koh Rayang Nok features small, white, sandy beaches and beautiful crystal clear seawater. There is one resort on Koh Rayang Nok with a small beach offering peace and quiet and good snorkeling spot.
- Koh Phi is off the northwest coast of Koh Mak and can be reached by kayak from Koh Mak Cococape Resort. It is a good spot to snorkel.
- Koh Kham is a small white sandy beach with black volcanic rocks. It is 1 km away and, same with Koh Phi, can be reached by kayak from Koh Mak Cococape Resort. One can also wait for low tide when a sand dune appears that enable walking from Koh Mak to Koh Kham. It is a small island with aged lava, proving the existence of a volcano in pre-historic times.
- Koh Kradad is off the northeast of Koh Mak. It can be reached by paddling a canoe from The Cinnamon Art Resort & Spa. The island is flat where there is only one resort and a few kilometers of white sand beach along the east coast.
- 400 meters west of Koh Kood is Koh Raet -- a small island with a short sandy beach and blessed with a rich coral reef.
- To the west of Koh Mak is Moo Koh Rang which is comprised of 12 islands. Koh Rang Yai is the largest, covered with tropical rainforests and has the longest and most beautiful beach in the area. It has a hilly terrain and it’s quite flat at the shores. Divers can enjoy the scenic underwater beauty up to 25 meters deep. The San Chao Beach features powdery white sand and crystal clear water. Northwards from the beach is a Marine National Park Ranger Unit where camping is allowed at a small fee and with the approval of the officer in charge. Here, you can avail of water supply and use of the toilets, but remember to bring your own food. In front of the Ranger Unit is a man-made bridge made by dropping rocks and stones into the sea. This bridge was built to help transport supplies from the International Red Cross Organization to Vietnamese refugees in the past. Further south is Koh Rang Lek, the main freshwater source with beautiful oval-shaped stones which have very smooth textures. Birds and bats are abundant in Koh Rang Lek, where there is a bird’s nest concession and also a major source of bat’s dung known to be great fertilizers. For the lucky few who come on the right season, they may see sea turtles laying eggs on the island as it has become a chosen nesting ground for the turtles. On the northeast of Koh Rang are Koh Kra, Koh Thong Lang and Koh Thain, popular sites for skin diving with abundant fishes and a vast array of varied corals. Of the three, Koh Kra has the longest beach at 20 meters. Swimming is discouraged, though, as the seabed is carpeted with corals. All these three islands are walking distance apart and the seawater is so shallow. Visitors are recommended to float with a life jacket or buoy in order to avoid stepping on some of the healthy corals. Koh Yak is a coral rock island with no beach and perfect for snorkeling.
