South Sourdough Trail is a ride at altitude! Starting at 9200ft with a climb right out of the gates this is one to be acclimated for, but don’t let that put you off. This is one of our favourite treed mountain rides, travelling through the Roosevelt National Forest - it’s a beautiful, peaceful challenge.

Route Description for South Sourdough Trail

Sourdough Trail is a straightforward out-and-back trail that travels through the beautiful Roosevelt National Forest. From the trailhead, the trail steadily climbs and gains elevation from its starting point of 9200ft.

After a brief level section of the route at a clearing in the trees, the trail will soon have you digging deep and gasping for breath as you continue to climb. After about 1600ft of climbing, the trail levels off and starts to trend downhill.

The end of the trail puts you at the gate for the Brainard Lake Recreation Area within the Indian Peak Wilderness. The way back is to follow your tracks back down to the trailhead.

Insider Hints

  • Sourdough Trail can be extended at the gates for Brainard Lake Recreation Area. Cross the road and continue on North Sourdough Trail and ride until you have had enough. Eventually, North Sourdough Trail ends at Peaceful Valley.

The altitude got me there a bit but I got used to it and after adjusting it was a great, hard but at the same time peaceful ride.

this biking trip was the hardest i've done. i usually hike but this time my friend invited me to get a bike. i really enjoyed it, although next time i would prepare in advance. it's not as easy as it may seem.
