Arriving on Koh Mook
Koh Mook feels different from Koh Kradan.
Koh Kradan is mainly about beautiful beaches, clear water and snorkeling. Koh Mook has more local life, small restaurants, shops and places to explore.
Your boat may arrive at Koh Mook Pier or another designated beach, depending on the service. Check the arrival point before you leave Koh Kradan so you know how to reach your accommodation.
If your hotel is away from the pier, you can arrange a local taxi or motorbike taxi after arrival.
What to Do After Arrival
There is no need to rush around Koh Mook.
After checking in, you can have lunch and explore the island. Walk through the local village, find a small restaurant, or simply spend the afternoon at the beach.
The biggest attraction is Emerald Cave.
The cave is reached from the sea. Visitors swim through a dark passage before reaching a hidden lagoon surrounded by limestone cliffs.
For this reason, many travelers choose to stay on Koh Mook for at least one or two nights rather than visiting only for a few hours.
