Thong Krut Pier

Thong Krut Pier operates as the primary launching point for boat excursions to Koh Tan, Pig Island, and other small islands scattered across the Gulf of Thailand off Koh Samui's southern coast. While the pier itself is a no-frills, functional waterfront rather than a destination in its own right, it draws travellers looking to explore beyond the main island — particularly those interested in snorkelling trips, fishing excursions, and multi-island day tours. The surrounding area has a quiet, local character that contrasts with Koh Samui's busier resort zones. Visitors can book boat tours directly at the pier from small operators stationed on-site, which reviewers consistently note is significantly cheaper than booking through hotels or online platforms. A private boat can be arranged for around 2,000 baht, and group tours covering three islands with lunch are also available. The island trips themselves receive strong praise, with Pig Island frequently highlighted as a standout stop. The nearby beach offers a relaxed atmosphere, though it is better suited to sunbathing than swimming. Good to know: Arriving by 9.30am gives travellers the best chance of joining an early departure, with first boats typically leaving around 10am. Bring cash, as smaller pier operators are unlikely to accept card payments. Sun protection is essential for any boat excursion, and checking weather conditions before heading out is advisable, as sea conditions affect boat schedules.
