Koh Samui has a few options for seeing elephants up close, but if you’re going to visit, it’s crucial to choose an ethical sanctuary.

That means no rides, no tricks, and no chains. The goal is to support places that prioritize the well-being of these incredible animals, not exploit them.

The Samui Elephant Sanctuary was the island’s first truly ethical facility and remains one of the most respected. Set on spacious, green grounds, it’s home to rescued elephants who’ve spent most of their lives in logging, trekking, or performance industries.

Here, they finally get to just be elephants, roaming freely, playing in the mud, grazing, and bathing on their own terms.
