Hike Lower Black Box Canyon

It takes some commitment to get to the trailhead, but it’s worth it. After several dirt roads, follow a rocky 4X4 road for about 10 miles to the trailhead. Sunscreen up and walk down the path to an open wash. This wash runs into the San Rafael River. At the river, check the flow, it should be below 50 cfs for a safe adventure. Cross the river and follow the trail that takes you above the canyon heading upstream. Watch out for poison ivy!

After an hour to ninety minutes, you’ll come to Swasey’s Leap, a narrow gap above the canyon that legend says Sid Swasey jumped across on his horse. If true, he’s a brave soul. Make your way down to the river just above Swasey’s Leap and let the fun begin!

The next hour of canyon is sheer bliss: swims, boulder hopping and incredible narrows. Then the canyon widens and deepens. Enjoy the black varnished walls that give the canyon its name as you work your way back to the place where you crossed the river initially. When you smell sulfur seeps, you’re getting close.

Follow the path back up to your vehicle and take a well-deserved break. You conquered a small part of the San Rafael and earned some serious bragging rights. The entire adventure will take 7-9 hours.
