Ko Hong Island | Blue Plankton Paradise!

What are Ko Hong Island and Beach Like?

Ko Hong Island is one of the islands that is close to Krabi’s mainland shore. In fact, it is just about 8 km off the coast of Tub Kaak Beach in West Krabi in the Nong Thalay Subdistrict. Ko Hong reminds us of Railay Beach West with its limestone rock faces shooting straight out of the water right next to the beach. This is a fantastically beautiful island oasis and one you shouldn’t miss if you have a chance to visit!

There is a place to eat and a few things to do like kayaking, swimming, snorkeling, and climbing up to the 360-degree viewpoint. There are restrooms and trash receptacles and of course, you’ll have a 400 THB fee for adults and 200 THB for children over 3 years of age because this is part of the Thanboke Khoranee National Park.

You can reach Ko Hong from Tub Kaak Beach, Noppharat Thara, or Ao Nang Beach. It’s 17 km from Ao Nang and kind of a long ride on a slow long-tail boat. It’s quite remote and will give you that feeling of isolation you may be craving, even though it is likely to have some other tourists on the island with you at the same time.

Restaurant and Food Stands?

There is one food area with hardwood tables, chairs, and benches called “Food Service.” This has some basic Thai food meals and snacks, including an assortment of cold drinks to refresh you in the heat of the day. There is a small bar and coffee shop called Bi Le Bar Cafe where you can get some drinks and caffeine to get you going before you climb the 400+ stairs leading to the stunning viewpoint.

There is no alcohol allowed to be served here because it’s a national park. It shouldn’t be called “Bar” at all.

Google Business Reviews

The island has nearly 3,500 reviews from visitors and gets 4.7 out of 5 stars. Most guests loved the location, the wide sand beaches, the incredibly clear and blue/green water, the fun things to do, and the viewpoint is something everyone that could – enjoyed doing.

Tips for Visitors

  • May through October is the low season and the fewest tourists. If you’d like to see fewer people, this is the best time to visit Krabi.
  • Save money on islands by bringing your own snacks and water. Island prices are really expensive and if you’re willing to carry a little more in a backpack or bag, you’ll save considerable cash.
  • The sun is relentless. Bring along an umbrella, sunscreen, a hat, and sunglasses to protect yourself from the sun on boat rides. Especially long boat rides over 10 km. Bring earplugs too because some long-tail boats will break your eardrums!
  • Respect the island’s natural environment. Don’t litter, or damage the coral. Don’t smoke or leave cigarette butts around. Clean up after yourself and children.
