Reviews: Koh Samui Jungle Elephant Sanctuary Half Day Tour
Guest User2025-11-21
Wow what an amazing day! The pick up was on time and hassle free direct from my hotel. It had been raining so I think that meant a few cancellations, all the better for me who ended up in a small group of just 5. John was our guide. A lovely intro with a nice coffee. Then we got to meet and feed some gorgeous elephants. And a great photo opportunity . We then went to meet the rest. (They have 7 at this sanctuary). Plenty chance to ask questions and know everything about their elephants. A quick coffee then change for a chance to shower and brush the elephant. This was fantastic! What a wholesome , amazing day ! I definately recommend you visit when in samui
