Why go

On the mainland coast opposite Samui, a small resident population of Indo-Pacific humpback dolphins feeds close to shore. They turn pink with age — the pigment fades and the blood shows through — and Khanom is one of the few places they can be seen from a small boat.

What you will find

The day involves the car ferry or a speedboat crossing, then a local longtail out at first light. Khanom itself is a quiet stretch of empty beaches and limestone hills, with a couple of caves and waterfalls inland worth the detour.

Good to know

Early morning, calm sea, and no guarantee: they are wild animals.

Worth knowing before you go

They are wild animals: no sighting is guaranteed, and any operator promising one is not telling you the truth. Early morning and calm sea give the best odds.

Koh Madsum's larger neighbour, ringed by the healthiest reef within reach of Samui and home to a handful of families.

Koh Madsum (Pig Island)

Twenty minutes off the south coast: a white sandbar, clear shallow water and a small herd of pigs that come down to the beach.

Wat Laem Sor & its golden chedi

The far south coast, and the least visited good temple on Samui: a chedi covered in golden-yellow tiles standing on the sand, with the sea behind it.
