Reviews: Samui Elephant Kingdom Sanctuary - Elephant Feeding|Skywalk|Trending Elephant Cafe
Guest User2026-07-18
The elephants are wonderful; they line up for feeding, making funny sounds. Some are young and playful, very funny, while others are not so young, slower, and very sweet. The elephants are well cared for and cleaned. We only paid an entrance ticket, and they gave us baskets of food for feeding, which was very interesting. Those who took a guided tour were able to make treat balls, which the elephants love. The entire tour and feeding took about 45 minutes. It's a bit pricey, but I think all the money goes towards caring for the elephants. The grounds are beautiful and well-maintained.

The pigs simply stole our hearts. We never would have thought we loved pigs so much. 😁. Definitely a must-see!

Reviews: 1-day tour to Mu Ko Ang Thong National Marine Park from Koh Samui [snorkeling/lunch/transfer/kayaking]
Guest User2026-09-08
The route matched the description. The excursion itself was wonderful. I highly recommend it. We were with the Funny Day team. They're great guys, but there was one major drawback I didn't like. On the way back from the archipelago to Koh Samui, we ran out of gas. Oh well, it happens. We first took some gas from a boat traveling alongside, but it wasn't enough. Then we waited for a second boat to bring gas and pick up some of the people. And it seemed like everything should go smoothly from there, but no! The new boat also ran out of gas 100 meters from the beach. And we waited for a third boat. They need to fix this urgently and bring extra gas. Otherwise, the excursion itself, the views, the snorkeling, and the kayaking were amazing. The views from the observation deck are incredibly beautiful, but the climb is very difficult and is best done in sneakers.
