Mooring buoys
Picking up moorings at an anchorage like Koh Muk, instead of dropping anchor, is increasingly necessary as authorities scramble to preserve coral. Be prepared to move if asked to do so by the mooring’s owner or a local authority. Remember, it’s your responsibility to check moorings in terms of their availability, condition and suitability for your yacht. Be aware that some moorings are suitable for small, light boats only.
Overview
Ko Muk, a gem in the Trang group, offers pristine beaches, a welcoming village, and one of Thailand’s most famous natural attractions – the Emerald Cave, just 1NM north along the coast. The approach is straightforward, and the anchorage off Hat Farang (Charlie Beach) provides good holding in mud.
Depth & Holding
Anchor in 6m on a muddy bottom. The holding is excellent and shelter reliable in the northeast monsoon, though exposed in the southwest.
Ashore
The island has small resorts and restaurants, with the local village – a pleaant 20-minute walk across to the east coast – offering basic provisions. Motorcycle taxis with sidecar are available. Perched high on, and jutting out over, the rocks at the southern end of the bay is a no-name, family-run, restaurant with good food and a warm welcome for yachties.Longtail boats can be noisy during day but fade at sunset.
Highlights
Swim through the Emerald Cave – a hidden lagoon accessed via a short sea tunnel. It’s best at mid-tide when sunlight turns the water emerald green.
Why we like it
Ko Muk delivers all the Andaman charm in miniature – beauty, simplicity, and a sense of discovery just a day’s sail from Kantiang Bay on Koh Lanta.
