In the interior of northwest Pulau Bintan, the tropical jungle suddenly gives way to a bizarre, otherworldly landscape known as Gurun Pasir Busung. Originally an abandoned clay and sand excavation site, decades of wind and rain have sculpted the earth into a vast expanse of rolling white and golden sand dunes. These five trekking routes guide you across this high-contrast, desert-like terrain, offering a stark, minimalist escape that feels completely removed from the typical palm-fringed coastlines of the Riau Island
1. The Dune Navigating
This trek begins at the main western entrance of the Busung dunes, just off the main Tanjung Uban highway. As you lace up your boots and crest the first major ridge, the tropical greenery completely drops out of sight, replaced by a sweeping landscape of wind-swept white sand peaks that mimic the empty quarters of a desert. Walking along the narrow, shifting ridges requires a slow, deliberate pace as the soft sand gives way beneath your feet. The trek challenges your endurance under the open sun, forcing you to focus entirely on the horizon line and the minimalist geometry of the dunes stretching out before you.
2. The Turquoise Oasis
Following a rugged trail that drops into the deep center depressions of the Busung valley, this route leads you directly to a series of hidden mineral lakes. These striking bodies of water are formed when rainwater accumulates in the deep, excavated pits, reacting with the high concentrations of kaolin clay in the soil to turn a brilliant, milky turquoise blue. The contrast between the blazing white sand slopes and the completely still, neon-blue water creates a striking visual mirage. Sitting at the water’s edge in the absolute silence of the canyon floor provides a cool, surreal intermission during your trek across the dry dunes.
3. The Desert Photography
Timed precisely to begin two hours before sunset, this route snakes through the highest peaks of the eastern Busung sector, where the wind creates perfect, rippled patterns across the sand. As the equatorial sun dips lower, the harsh white light softens into a deep amber, casting long, dramatic shadows that sharply define the crests and valleys of the earth. This trek is designed for those who use the camera lens as a tool for mindfulness, guiding you to capture the high-contrast silhouettes, sharp lines, and changing textures of a tropical desert during the golden hour.
4. The Basalt Ridge Scrambling
For a more physically demanding journey, this trail takes you to the rugged northern perimeter where the soft sand dunes collide with ancient, red-earth canyons. Here, you will scramble up steep ridges made of hard, weathered basalt clay and exposed ironstone formations that have resisted erosion. The terrain turns from smooth sand to sharp, rugged paths, requiring you to use your hands for balance as you climb. Reaching the summit of these deep red cliffs rewards you with a fascinating, high-contrast panoramic view of the white desert on one side and the dense, green Bintan jungle on the other.
5. The Solitary Stargazing
This night expedition begins as the twilight fades, taking you deep into the central, darkest plateau of the Busung dunes, far from the lights of the coastal resorts. Once you reach the center, you will lie flat on a woven mat on the crest of a high dune, letting the ambient heat trapped in the sand warm your body. With zero canopy overhead and a complete lack of light pollution, the equatorial night sky opens up with astonishing clarity. Tracking the path of stars and the pale band of the Milky Way across the vast, dark dome while surrounded by a silent desert of sand offers a powerful sense of isolation and scale.
