Koh Mah Half Day, Private
Half a day, your own boat, one very good reef
A private half day at Koh Mah — shallow, sheltered coral a short run from Lanta. Morning or afternoon, THB 6,000 for up to five people.
Koh Mah sits close enough to Lanta that you are in the water quickly, and the snorkelling there is shallow and sheltered — which makes it the trip we point nervous swimmers and families with young children toward.
It runs as a private charter only, so the boat is yours for the session. One price covers the boat for up to five people, which makes it unusually good value for a couple or a small family compared with paying per head on a join-in trip.
Pick the morning or the afternoon. The morning slot generally has the flatter water; the afternoon is quieter.
Highlights
- The whole boat for up to five people at one price
- Shallow, sheltered coral — good for nervous swimmers
- Choose the morning or the afternoon
- Short run out, so more time in the water
