Hin Sam Wan (Three Whale Rock) is a must-see natural wonder in Bueng Kan, Thailand's youngest province. The site is named for its three giant sandstone rocks that, from a certain angle, look like a family of whales swimming together. These majestic rocks are a testament to millions of years of natural erosion.

Located within the Phu Sing Forest Park, the area is part of a lush, rich forest reserve. This makes it an ideal destination for nature lovers and photographers looking to capture spectacular landscapes.

The main highlight of Hin Sam Wan is its incredible viewpoint. From the top of the rocks, you get a 360-degree view of the surrounding forests, the meandering Mekong River, and the mountains of Laos across the border. It's particularly popular for watching the sunrise, as the early morning light creates a magical atmosphere over the misty landscape.

The site is not just about the three main rocks. The entire park is filled with various interesting rock formations and cliffs, making it a great place to explore. It's a perfect spot for those seeking an off-the-beaten-path adventure and a chance to connect with nature. 

• By Private Vehicle: Drive approximately 25 kilometers from Bueng Kan city center along the Mekong River road. Note that only pickup trucks or 4x4 vehicles are permitted to drive up the steep mountain path.

• By Foot: You can park your car at the designated parking area near the Tham Ruea Si (Hermit Cave) campsite and then walk the final 200 meters to the rock formation.

• By Local Service: For a safer and more convenient journey, you can hire a local pickup truck with a driver from the park's entrance to take you up the mountain.

• Visit early in the morning to catch the spectacular sunrise and avoid the heat.

• Wear comfortable shoes and be careful when walking on the rocks, as some areas can be slippery.

• Check the weather forecast before you go, as the path can be muddy during the rainy season.
