Each Thursday, the Red Baron, Koh Samui's most luxurious cruise boat, sails to Angthong National Marine Park, one of Thailand's most idyllic paradises. This traditional Thai sailing junk, a twin-masted, red-sailed icon in these parts, is the biggest of its kind in Koh Samui and the Gulf of Thailand. Spend a day in traditional luxury as you glide past the inspiration for ‘The Beach' and snorkel or swim in the crystal clear waters of this 40-island archipelago. Or, if you'd prefer, simply relax on deck with a refreshing drink in hand as you wait for the mouthwatering lunch buffet and barbeque to be served. You can chill in the covered saloon, visit the lounge bar, fish from the designated platform or claim your spot on a comfortable sun lounger.
