Questions
Before you book.
Can I join from Koh Phangan?
Yes. This tour departs from both Koh Phangan and Koh Samui, with hotel pickup on both islands.
Is the park fee included?
No. You pay it in cash at the park: 300 THB per adult and 150 THB per child.
Can I swim in the Emerald Lake?
No. Swimming in the lake is not allowed. You see it from a viewing platform at the top of a short stairway.
How long is the boat ride from Koh Phangan to Ang Thong?
About one hour by speedboat, a little less from Koh Samui. The boats return to Koh Phangan and Koh Samui around 16:00–16:30.
How hard is the viewpoint climb on Koh Wua Ta Lap?
It is steep and rocky with ropes in places, about 40–45 minutes up and down. It is optional: you can swim and relax on the beach instead.
Is lunch included, and are there vegetarian options?
Yes. A Thai lunch is included, with vegetarian options. Tell us about allergies when you book.
Can I book the Ang Thong day tour in November?
The park is closed from 1 November to 15 December. You can already book for 16 December onwards, or join the Koh Tao & Koh Nang Yuan day trip, which runs all year.
What happens if the weather is bad?
Rain alone does not cancel a trip; strong wind and waves do. Your captain checks the sea every morning. If we cancel because it is not safe, you choose a full refund or a new date, and we tell you by WhatsApp and email as early as possible.
Can I cancel or change my booking?
Yes, free of charge up to 48 hours before departure: a full refund or a new date, subject to availability. Within 48 hours of departure, or if you do not show, the booking is charged in full. Refunds go back to your card within 5–10 working days.
How do I book, and when is my booking confirmed?
Choose your trip, date and guests on the tour page and pay securely by card through Stripe. We check the boat and confirm by email and WhatsApp with your pickup time and pier. For trips tomorrow or today, message us on WhatsApp first. Private boats and transfers are booked by message with a fixed price.
What time is pickup, and is it included?
Pickup is usually between 07:30 and 08:30; your exact time comes by WhatsApp the evening before. Pickup is free from most hotels on Koh Phangan and Koh Samui. Thong Nai Pan and Than Sadet (Koh Phangan) and Nathon, Lipa Noi, Bang Kao and Thong Krut (Koh Samui) are +400 THB per person return. Bottle Beach, Haad Wai Nam and Haad Yuan have no road, so there is no hotel pickup there; we meet you at the nearest agreed point. You are back at your hotel around 16:30–17:00.
Are the tours suitable for children and non-swimmers?
Yes. Life jackets in children’s sizes are included and children wear them on the boat at all times. Snorkelling, kayaking and the viewpoint climb are optional, so non-swimmers and grandparents can enjoy the beach. Boat trips are not recommended in pregnancy or with back problems, because the boat crosses open sea.
