How to Choose an Ethical Dolphin Tour in Koh Samui

By the Dolphin Tour Samui team · 2026-10-19 · 5 min read

A good dolphin trip is good for the guests and for the animals. Use this checklist before you book with anyone, including us.

Watch, don't chase

Ethical viewing means approaching slowly, never racing toward the animals and never encircling a group. Commonly cited local guidance asks boats to slow down well before reaching a group and to cut the engine if dolphins come close. Ask the operator what their crew does when dolphins appear.

Avoid feeding, touching and captive swim programmes

Wild dolphins should not be fed or touched. Programmes that keep dolphins in captivity for swimming are widely criticised by conservation groups. A wild-watching trip should be about observing from the boat.

Prefer small groups

Fewer boats and fewer people mean less pressure on the animals, a calmer experience for you and more freedom for the crew to pick a route. Ours is a private-boat trip with one departure per day.

Look for honest promises

Be careful with anyone who guarantees dolphins. A responsible operator is clear that sightings are never certain and says what happens if you don't see any. Ours: book direct, and if there are no dolphins you choose a full refund or a new trip. See the full policy.

Check the basics

Ask for the operator's licence number. We are licensed by the Department of Tourism (No. 44/00448). Check that life jackets are provided, that hotel pickup is clear and that the price is confirmed in writing.
