The Sinks Canyon Trail

The Sinks Canyon Trail is a short and sweet adventure to a unique geological site sure to mystify. While the route is open year-round, the park and the road are unmaintained in the off-season. Winter exploration also presents inherent challenges, the main being slippery conditions, notably around the cavern and on the rocky river banks! Though not the busiest trail in the state, this route sees plenty of curious day-trippers, so we encourage early morning exploration for a more tranquil experience. As with all hikes and adventures in the area, make sure you or someone you are with carries bear spray!

Beckoning curious tourists, geologists, and history buffs alike, this natural anomaly will never cease to amaze. Though there is a small network of routes in the area, the Sinks Canyon Trail is the most direct and family-friendly option. Wander along the meandering river and notice the water bubbling up from the Rise before reaching the impressive cavern where the river flows into the cracks and crevices, disappearing underground. While impressive year-round, springtime exploration offers impressive views of blooming wildflowers and water surging through the Overflow Channel. Don’t forget to take your camera; the scenery is quite photogenic.

Your journey along the Rise Canyon Trail begins from the Sinks and the Rise Trailhead off the Sinks Canyon Road. At this point, you will explore the Rise. Admire the anomaly of the bubbling water. Marvel at the sights, then track the Sinks and the Rise Trail southwest parallel to the Sinks Canyon Road. As you wander this route, wonderful views of the Sinks Canyon and the foothills of the Wind River Range will unfold before you. After some hiking, the route will cross over the Sinks Canyon Road—exercise caution as you cross this route.

Reconnecting with the Sinks and the Rise Trail, you will be led south through abundant wildflower meadowlands, and sparse tree stands. Nearing the Popo Agie River, you will likely notice a stretch of smoothed rocks which is usually barren, but in the spring, this channel is surging with overflow snowmelt that missed the mark of the Sink Cavern. Continue trekking this route, and you will likely notice the company of more explorers heading to the Cavern.

After passing the visitors center, you will reach the Sink. Take the time to explore this geological site. Revel in the scene of the water vanishing into the limestone cavern floor. While you will likely notice intrepid adventurers exploring the cave up close, this is not recommended as the terrain is extremely slippery, and humans can negatively affect the fragile environment. Admire the intricacy of the cavern and take the time to realize how far it travels underground before resurfacing at the Rise. Snap a few photos, then head back the way you came to the trailhead.

Trail Highlights

The Sinks and the Rise

Located on the Popo Agie River in the Sinks Canyon are the geological mysteries known as the Sinks and the Rise. Nestled between the towering limestone walls, the Popo Agie River mysteriously disappears beneath the ground, appearing again hundreds of yards away. What is known as the Sinks is the limestone cavern where the river vanishes, and the Rise is just north where the water reappears. It is likely that the glaciers created the Sinks and Rise in the Ice Age.
