How to Get from Koh Mook to Koh Kradan: Island Hop Guide 2026

Is Koh Kradan worth visiting? I took a longtail boat from Charlie Beach on Koh Mook one morning and twenty minutes later jumped into waist-deep water because the island has no pier. That should tell you everything about what kind of place this is. Crystal water, empty beaches, no infrastructure, and some of the best snorkeling in the Andaman Sea right off the sand. This guide covers the crossing, the costs, the park fees, and the timing details that make or break your visit.

Quick Info

Is Koh Kradan Worth Visiting as a Day Trip from Koh Mook?

Yes, without hesitation. Koh Kradan sits inside Hat Chao Mai National Park. The main beach, Paradise Beach, stretches 1.5 kilometers of white sand with a coral reef starting just 150 meters offshore. The water clarity on a calm morning rivals anything in the Maldives. On the opposite side, Sunset Beach hides behind a short jungle trail with almost no visitors.

The koh kradan day trip from koh mook works perfectly because the islands sit so close together. Twenty minutes by longtail. You leave after breakfast, spend the day snorkeling and swimming, and return before sunset. The only challenge is timing. Tour boats from Koh Lanta and Trang arrive between 10:30 and 14:00. During those hours, Paradise Beach fills up. Before and after that window, the island feels almost private.

There are no organized day tours from Koh Mook to Koh Kradan. You arrange your own boat. However, if you are based in Koh Lanta, several tours include Koh Kradan as a stop. The 4 Islands longtail tour covers Koh Kradan with snorkeling and beach lunch. The Kradan Island longtail tour from Lanta focuses specifically on this island. A speedboat version is also available for a faster crossing.

How to Get from Koh Mook to Koh Kradan Without a Tour

Getting from Koh Mook to Koh Kradan independently is straightforward once you know where to go and what to expect.

Finding Your Boat

Head to Charlie Beach on Koh Mook’s western side. Longtail captains park their boats along the sand. Walk up, ask for Koh Kradan, and negotiate the price. There is no ticket office, no schedule board, no booking app. It is a face-to-face conversation on the beach.

A private longtail costs 1,200 to 1,700 THB for the entire boat. This works well for couples or small groups. If you find other travelers heading the same direction, a shared longtail runs 300 to 500 THB per person with a minimum of four to six passengers. Tigerline operates a speedboat for 1,100 to 1,200 THB if you want a faster crossing.

The Wet Landing

I negotiated with a captain at Charlie Beach around 07:30. We agreed on a price, boarded the longtail, and crossed in about twenty minutes. When we reached Koh Kradan, there was no pier. The captain pulled the boat as close to the beach as the shallow water allowed, looked at me and said “jump.” I stepped off into waist-deep water, holding my backpack above my head. If I had not put my phone in a waterproof pouch that morning, this guide would not exist. Koh Kradan has no jetty, no dock, no dry landing option. A waterproof bag for your electronics is not optional here.

National Park Fees

Koh Kradan sits inside Hat Chao Mai National Park. Entry costs 200 THB for adults and 100 THB for children. Payment is cash only at the beach checkpoint. Keep your receipt.

The park ranger handed me a receipt after I paid. I folded it and put it in my pocket without thinking much about it. Later that day, when we visited the Emerald Cave on Koh Mook, the boat captain asked to see the same receipt. It works as a same-day pass across all Hat Chao Mai National Park sites. The tourist next to me had lost his receipt and paid another 200 THB at the cave entrance. One small piece of paper, 200 THB saved. Keep it until you are back at your hotel.

What Not to Do

Do not attempt to kayak from Koh Mook to Koh Kradan. The open Andaman Sea between the islands has strong currents and unpredictable swells. Several travel blogs suggest it casually. It is genuinely dangerous. Take a longtail.

Also be aware of double park fee risk. If your boat crosses into the Mu Ko Lanta National Park boundary, you could face an additional 400 THB charge. Confirm with your captain that you are staying within Hat Chao Mai park limits.

How Many Days or Hours Do You Need on Koh Kradan Island?

How many days in Koh Kradan depends on your style. A day trip covers the highlights comfortably. Four to six hours gives you time to snorkel the reef, swim at Paradise Beach, walk the jungle trail to Sunset Beach, and eat lunch at one of the small beach restaurants.

Staying overnight transforms the experience completely. The day-trippers leave by 15:00. After that, the entire island belongs to you and the handful of guests at the small resorts. Sunset on the western beach, stars with zero light pollution, morning snorkeling before anyone else arrives. Two nights is the sweet spot if you want depth without running out of things to do.

Best Time of Day to Cross the Andaman Sea for Clear Snorkeling

The koh kradan snorkeling guide basics come down to timing. The clearest water window runs from 07:30 to 10:00. Morning light penetrates deepest, plankton is minimal, and boat traffic has not stirred up the sand yet.

Check the tide table before you go. High tide is better for snorkeling because the water depth over the reef gives you room to float without touching the coral. Low tide exposes shallow sections where you risk scraping your knees and damaging the reef.

Paradise Beach reef sits 150 to 200 meters offshore. Ao Nieng reef on the southern tip starts just 50 meters from the sand with a dramatic drop-off. Clownfish, parrotfish, and sea urchins fill both sites. If you only snorkel one spot, choose Ao Nieng for the variety and the wall dive feel.
