Questions
Before you book.
Is the Koh Nang Yuan fee included?
No. It is 250 THB per person, paid in cash on arrival. Single-use plastic bottles are not allowed on the island; water is provided on the boat.
Can non-swimmers join?
Yes. Snorkelling is optional and life jackets are provided for everyone.
When does the Koh Tao trip run?
Every day, all year round, whenever the sea is safe. While Ang Thong is closed (1 November – 15 December) it is our most popular day trip from Koh Phangan and Koh Samui.
How long is the speedboat to Koh Tao?
About one hour from Koh Phangan. From Koh Samui it takes about 1.5–2 hours including a stop on Koh Phangan.
Is lunch included?
Yes, a Thai lunch on Koh Tao with vegetarian options, plus water, soft drinks and fresh fruit on the boat.
Do I need my own snorkelling gear?
No. Masks and life jackets are provided. Standard fins are not allowed in some protected areas.
Which snorkelling spots do we visit?
Koh Nang Yuan and the Japanese Gardens, then two bays around Koh Tao chosen on the day for the calmest water, such as Mango Bay, Hin Wong or Aow Leuk.
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.
