The Mekong River, a significant waterway flowing from Thailand’s northern border to its northeastern side, traverses numerous provinces before reaching Khong Chiam district in Ubon Ratchathani province. This district serves as a pivotal gateway to the southern part of the Isan region. Along this journey, there are plenty of enjoyable activities to experience.
Take a boat trip to see the rapids at Sam Phan Bok

Sam Phan Bok, often called the Grand Canyon of Thailand, is a vast area of mountain-like rapids situated in the middle of the Mekong River. It features over 3,000 basins that have been sculpted by water currents into intricate and visually striking formations when viewed beneath the river’s surface. This natural wonder resembles a work of art amidst its stunning and unique landscapes. Each eroded sandstone basin at Sam Phan Bok exhibits a distinct shape, allowing visitors to perceive them in various forms such as heart-shaped rapids or resembling animals, depending on one’s imagination. This diversity adds to the allure of Sam Phan Bok, offering a natural spectacle that showcases the creative power of nature.

During the dry season from November to April, the rapids of Sam Phan Bok emerge above the water’s surface. To reach Sam Phan Bok, embark on a scenic boat ride spanning approximately 4 kilometers. The journey begins at “Salung Beach” and continues through “Pak Bong,” an area where the Mekong River narrows to form a natural bottleneck, with its narrowest point measuring only 56 meters wide. This boat ride offers a serene and picturesque route to witness the unique beauty of this remarkable geological formation.

Nearby is a small desert hill known as Had Hong. The scenery is stunningly beautiful and provides a feeling as if you are in the middle of a desert in a foreign land.
