    Discover the Beauty of Hong Island: A Thrilling Speedboat Adventure

    From฿ THBper person · all-inclusive

    Hong Island (Koh Hong) sits in Krabi province, about 50 km east of Phuket by direct speedboat — versus the 180 km road route via Phang Nga's coast. The island's headline feature is the hong itself: a sea-level cave entry that opens into a hidden interior lagoon enclosed by towering limestone walls (hong is Thai for "room"). Day-tour boats from the Krabi side reach Hong Island from late morning onwards; the quieter window is reached by departing earlier from Phuket's Boat Lagoon Marina on the direct sea route. National park fees are included on every Simba Sea Trips Krabi departure.

    Why the sea route from Phuket beats the road

    The transit math is striking: by road, Phuket to Krabi’s Ao Nang pier is roughly 180 km — three hours-plus each way before you even board a longtail or ferry for the final 30-40 minute crossing to Hong Island. By direct speedboat from Boat Lagoon Marina, the same destination is around 50 km — well under an hour and a half. A road-based Hong Island day trip from Phuket spends most of the day in a van. A sea-route trip arrives early, leaves late, and spends the day at the islands. The other consideration is timing: Hong Island gets busy from late morning onwards as the Krabi-side day boats arrive from Ao Nang. The early sea-route window is materially quieter.

    Krabi Luxury Private Charter — from ฿41,690

    Simba Sea Trips’ main route into Hong Island is the Krabi Luxury Speedboat Private Charter — an 8-hour private charter for 2 to 20 guests departing Soho Pool Club at Boat Lagoon Marina. From ฿41,690 THB at the base group rate, all-inclusive (transfers, national park fees, light breakfast, buffet lunch, snorkel equipment, soft drinks). The route visits Hong itself, Hong Lagoon, Railay Beach, Chicken Island, and hidden hongs that the day-boat fleet doesn’t reach. For deeper context on the destination — geology, tide windows, the four “hongs” worth visiting — see our long-form Ko Hong Island guide.

    What to expect at Hong Lagoon

    The hong is a circular interior lagoon enclosed by limestone walls roughly 100 metres tall. Entry is via a low sea-level cave opening on the island’s seaward side — at low tide the opening is clear and easy; at high tide it can close completely, depending on monthly tidal range. The architecture is geological: collapsed cave roofs over millennia left a karst chamber open to the sky inside, accessible only by water through the original cave mouth. The experience inside is the silence — the lagoon’s interior is sheltered from the open sea and from the wind, with only the sound of paddles or distant gulls. Bring reef-safe sunscreen, a dry bag for camera kit, and a hat.

    What Guests Say About This Tour

    TripAdvisor★★★★★

    Yet another perfect tour with Team Simba. (DO NOT BE PUT OFF BY THE EARLY START TO THE DAY ITS DEFINITELY WORTH IT!!). Today Joseph, Captain & David took us on a brilliant boat trip with something for everyone. They stopped the boat en-route to Maya Bay to allow us to watch the sunrise. Amongst the first to arrive at Maya Bay, it was such a beautiful and peaceful place to enjoy the tasty breakfast, Simba provided. The stop by the monkeys and Viking Cave were interesting. The snorkelling was wonderful. It felt like you were swimming in a fish tank with all the beautiful fish. Joseph went out of his way to point out squid and other fish to us. A final stop on the beach to dry out before lunch was lovely. Lunch at the Yacht Club was perfect. They catered for our food allergies and was a perfect way to round off the day before the driver took us back to our accommodation. THANK YOU - what a special team of people you all are.

    Incredible experience with Simba. Although they are more expensive than other providers they are well worth the experience. They take a max of 18 people, although we only had 8 and 3 staff. Our captain, guide Noi Noi and deckhand David. All 3 were incredible and Noi Noi and David would get in the water and point out the sharks, snakes and fish for us to see. Being one of the first on Maya Bay meant less crowds and great photo opportunities. Then at every stop there after we were one of very few boats or the only people. The snacks were plentiful on the boat and the lunch back at the Marina was some of the best Thai we’ve had. Overall this was an incredible experience and a trip definitely paying additional for.

    An Absolutely Unforgettable Experience – Highly Recommended! This was truly one of the most incredible experiences of my life! A huge thank you to the entire Simba Sea Trips team, especially our wonderful tour guide, Mr. Noi, who was exceptionally kind, attentive, and knowledgeable throughout the day. We saw baby sharks, clownfish, and stunning rainbow-colored tropical fish while snorkeling. It honestly felt like swimming in an aquarium! The team knew exactly where to find the different marine species and guided us to the best spots, making the experience even more special. Everything was perfectly organized, from the snorkeling equipment and fins to the constant snacks and refreshments. The boat was extremely comfortable, and every little detail was thoughtfully taken care of. We couldn’t have asked for a better experience! It was truly magical, and we will remember this day forever. If you’re visiting Phuket, this tour is an absolute must! Thank you, Simba Sea Trips, and…
