Koh Madsum (Pig Iisland) (4hrs)

Most yacht charters stick to the obvious spots, but smart travelers know the real magic happens at Koh Madsum (Pig Island, Koh Mutsum) – where swimming pigs actually paddle out to greet you in crystal-clear waters. You'll find that Thailand waters offer this bizarre yet delightful encounter just 15 minutes from Koh Samui's coast.

The Moondancer Princess Yacht 42ft makes perfect sense for Thailand's tropical conditions. Air-conditioned comfort matters when the sun hits 35°C, and this motor yacht's spacious layout keeps eight guests comfortable while island-hopping. What matters in Thai waters is having reliable shade and cold drinks – both covered here.

Also worth noting about Thailand, the cool season from November to February offers ideal conditions for this half-day adventure. Even during monsoon months, tropical showers are brief and refreshing – part of the authentic experience. It is recommended to bring reef-safe sunscreen because Thailand's equatorial sun shows no mercy.

The pigs themselves steal the show, swimming confidently toward boats for treats and photo opportunities. These aren't your average farm animals – they're skilled ocean swimmers who've turned tourist interaction into an art form. Weather can change quickly in tropical waters, but that's half the adventure of exploring Thailand's lesser-known gems.

Four hours gives you plenty of time for swimming, snorkeling, and pig encounters without rushing. As good as it gets in Thai paradise.
