Join a day trip to Angthong National Marine Park, departing from your hotel on Koh Phangan. First, you'll travel to Thongsala Pier, where you'll check in and enjoy light refreshments before stepping aboard a speedboat.

The adventure unfolds with a scenic cruise through the archipelago of Angthong. Be awestruck by the sight of 42 limestone islands emerging from emerald waters as you make your initial stop at Koh Wua Ta Lap. Here, a moderate hike offers panoramic views of the entire park. Further exploration leads you into the Lotus Cave (Bua Boke), where you can admire ancient stalactites and stalagmites.

Your next stop is the Emerald Lake (Thale Nai), a hidden saltwater gem enclosed by towering limestone cliffs. A brief hike takes you to a viewpoint where you can capture stunning photos. Afterwards, you'll have time to unwind on the beach, swim, and enjoy a Thai buffet lunch.

The journey continues to Koh Mae Ko. Here, you'll have the chance to paddle along the coastline in a kayak, discovering caves and lagoons. Dive into the underwater world, snorkelling among colourful coral reefs teeming with marine life. As the day concludes, board the speedboat for your return trip to Koh Phangan.
