Hin Sam Wan sits within the Phu Sing National Forest Reserve in Mueang Bueng Kan district — a cluster of large sandstone rocks jutting out from the edge of a cliff. Viewed from the side or from above, they form the shape of three whales lined up: a father whale, a mother whale, and a baby whale, which is where the name comes from. The rocks sit on a high cliff edge looking out over the Phu Sing forest, with views stretching all the way to a reservoir and mountain ridges beyond. This spot has become a landmark that visitors to Bueng Kan make a point of capturing, especially in the early morning when a sea of mist and the first light of day fall across the rocks.
The thing to understand before planning your trip is that you can't drive a private vehicle up to Hin Sam Wan yourself. The road up Phu Sing is steep and narrow, and is managed by the local community — visitors must park at the service point at the base and transfer to a local shuttle to go up. There's a service fee charged per vehicle or per person depending on the point of departure. Once at the top, you'll walk the rest of the way to the Hin Sam Wan rock formation and other viewpoints on Phu Sing. The viewpoint itself is natural cliffside rock, and many points have no railings, so this is a destination where you need to plan carefully for the journey and pay closer attention to safety than you would at a typical in-town attraction. On this page, we review the Hin Sam Wan experience in depth — both what makes it impressive and what you should know before you go.
Hin Sam Wan (Three Whale Rock) — Whale-Shaped Rock Viewpoint on the Phu Sing Cliff, Bueng Kan
Most Hin Sam Wan trips start by driving to the service point at the base of Phu Sing, parking your private car there, and transferring to a local shuttle to go up, since the road up is steep and narrow and private vehicles aren't allowed to drive it themselves. The local shuttle drops you off at the top, from which you walk the rest of the trail on Phu Sing to reach Hin Sam Wan and the other viewpoints. Hin Sam Wan itself is a large rock formation jutting out from the cliff edge — viewed from the side, it forms the shape of three whales lined up. Visitors love standing or sitting on the rocks for photos with the forest and distant views behind them, especially in the early morning when there's a sea of mist and first light falling on the rocks. The atmosphere is that of a wide, open natural viewpoint in the middle of the forest.
Based on real reviews across multiple platforms, what people consistently praise is the view and the unusual shape of the rocks, which photograph beautifully. Many say it's well worth getting up early and transferring by shuttle, since you get to see the whale-shaped rocks, the Phu Sing forest, and sweeping panoramic views all at once. The early morning, when the sky is clear with a light mist, gets the most praise as the best time for atmosphere. The community's local shuttle system also gets praised for being well organized, with staff on hand to manage the trip up and down, making it convenient for visitors unfamiliar with the route — and it helps generate income for the local community.
As for what to brace yourself for, honestly: first, you must transfer to a local shuttle to go up Phu Sing — driving your own car up isn't possible, so you need to build in time for waiting for a shuttle and the shuttle fee. On busy holidays, there may be a queue. Second, and most important, the viewpoint sits on high cliffside rock, and many points have no railings, so walking out to stand or sit for photos on the rocks requires extra care. Watch your footing, follow the signage and the guidance of staff and guides, and don't get too close to the cliff edge, especially when the rock is wet or it's windy. Keep a close eye on children or elderly members of your group. On top of that, the sun on Phu Sing is strong with little shade, so bring a hat, water, and shoes with good grip. Plan carefully around transport, timing, and safety, and you'll have a fun and safe visit.

💡 Know before you visit Hin Sam Wan
The road up to Hin Sam Wan on Phu Sing is steep and narrow, and private vehicles aren't allowed to drive it themselves. You must park at the service point below and transfer to a local shuttle (a community pickup truck or tour vehicle) to go up. There's a fee per vehicle or per person as set. Check prices and shuttle schedules with staff beforehand — on busy holidays there may be a queue, so factor this into your plans.
A clear early morning is when Hin Sam Wan has the best atmosphere — first light falling on the rocks, cool comfortable air, and a chance of a sea of mist floating over the forest. Leave your accommodation before dawn to make the morning shuttle round in time. By midday the sun is strong with little shade, and neither the view nor the weather will compare to the morning.
Hin Sam Wan and the viewpoints on Phu Sing sit on high cliffside rock with no railings at many points. When heading out to stand or sit for photos on the rocks, take extra care — watch your footing, follow the warning signs and the guidance of staff and guides, and don't get too close to the edge, especially when the rock is wet or it's windy. Wear shoes with good grip, and keep a close eye on children and elderly members of your group at all times.
Many people want to visit Hin Sam Wan and Tham Naga Cave in one trip — it's doable and worthwhile, but know that the two sites are on different mountains in Bueng Kan. Tham Naga Cave is in the Phu Langka National Park area, and requires a separate queue booking and a separate trail hike, with its own system and schedule. Plan the day and timing for each site carefully, allow travel time between the two, and avoid trying to cram both into a single half-day.

Then head back down for lunch in town, and set aside another day or the afternoon to visit Tham Naga Cave, which is on a different mountain (the Phu Langka area) and requires a separate queue booking and trail hike.
