About Ko Mat Sum (Pig Island)
Yes, the pigs are the whole point, and yes, it's fun. This small island off the south coast has clear, shallow water and a resident group of pigs that laze on the sand and paddle about, which makes for an easy, light-hearted half-day boat trip. The water itself is genuinely pretty.
Manage your expectations, though. The swimming pigs are a fed tourist attraction, not a wild encounter, so treat it as the novelty it is. Be gentle with the animals and don't overfeed them.
Go in the morning at lower tide when the sandbar shows and the water is calmest. It's usually paired with nearby Ko Tan on a half-day tour out of Thong Krut, which makes a nice combination.
