    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.

    Simba Sea Trips Phuket delivers one of the most polished and memorable island experiences you can have in Phuket. The "Luxury Small Group Sunrise Phi Phi Island and Maya Bay boat trip" feels carefully designed from start to finish, with every detail handled before the crowds arrive, so the day begins in calm, comfort, and style. The breakfast at the SOHO Club is a lovely way to start the morning at 6 am, and the hospitality only gets better from there. On board, the food and drinks are well thought out, and the final buffet lunch at the beach club is a fitting finish, with good vegetarian options as well. What sets this trip apart is the attention to guests. With no boat carrying more than 18 people, the experience never feels crowded or rushed, and there is a real sense that everyone is being looked after individually. That extra care makes a huge difference, especially on a premium trip like this. A special mention to our guide Noi Noi, whose witty commentary, deep knowledge, and genuinely personal attention made the journey even better. He had a wonderful way of making everyone feel included, and it was impressive to see first-time snorkelers, including guests who did not know how to swim, confidently enjoying the Phi Phi Don waters under his guidance. Our speedboat captain Dan Dan was amazing and how he guided through the choppy waters still keeping the boat steady and stable. Simba is a highly professional, luxury experience that is absolutely worth every penny.
