Mu Ko Ang Thong National Marine Park is a stunning archipelago of 42 islands in the Gulf of Thailand, offering breathtaking limestone mountains, dense jungle, pristine beaches, waterfalls, and hidden coves and lakes to explore. Activities include kayaking, snorkeling, diving, hiking, and simply relaxing on the beach. Accessibility can be limited depending on the tour operator and specific islands, with some requiring climbing or navigating uneven terrain. While solo visits are possible by hiring a private longtail boat, guided tours are recommended for ease of access and local knowledge. The park is generally open year-round, but the monsoon season (typically November-December) can bring rough seas and potential closures. A day trip usually costs between $50-$100 USD per person, including park entrance fees, boat transport, lunch, and some activities. A typical visit lasts a full day, from morning until late afternoon.
