The Rocks

Highlight (Segment) • Climb

This section up or down Mount Sanitas gets very technical with lots of rock scrambles.

Tip by

One of the most famous trails in downtown Boulder is known for its challenging terrain and easy accessibility, making it a popular choice amongst hikers in the region. To ensure a satisfying experience, it's crucial to begin your run early.

Lion's Lair Trail

Highlight (Segment) • Trail

The 'quiet' side of Mt. Sanitas, but why? What a fantastic trail! And if you run down this side you connect back on the road (sunshine canyon drive) pretty easily. It's usually not the busiest road, but be careful! :)

Lion's Lair Trailhead

Highlight • Trail

There's not really parking available, but this is the trail head of Lion's Lair leading you to Mt. Sanitas. We love this side of Mt. Sanitas, because it's quieter and it makes a nice loop from the other side.

Red Rocks

Highlight • Natural Monument

There are a lot of different views on the Red Rocks trails. The red sandstone rock formations in the area are what give this system the name Red Rocks Trail.
