Confirmed from Lions Lair And Sunshine Canyon Trails' own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.
Steep hiking path along a mountainside with scenic views of Boulder and Denver.
What runners say about Lions Lair And Sunshine Canyon Trails
“Oh and if you want to get a scenic view of Boulder, CO then this trail is definitely for You!”
“Walk 1 min up the road and you’ll see the access/clearly marked stairs to Lions Lair.”
Fun quick hike. A good view at the top and not too steep of ascent. Wasn't crowded when we went at 8 am but wasn't empty either
Beautiful trail, epic views, definitely recommend. I didn't spy any fountains or restrooms along the way. But it's a huge area with tons of paths so there could be facilities I missed. We approached the mountain from the valley to the East of the peak.
One of the most popular hiking areas in Boulder for good reason. Easy access. Steep ascents for a good workout rewarded by gorgeous views. A sunrise extravaganza!
One of the best trail routes from Dowtown Boulder. Follow sunshine canyon trail to the end ~2 miles from parking. Note Sunshine Canyon is Mapleton St as it heads into the foothills. Cross the road (Sunshine Canyon/Mapleton and turn left.
Trail conditions & character
“If you prefer to avoid steep Sanitas Mtn decent return the way you came making a great long out and back with views and few hikers.”
“Coming down (descending along the Western face, which overlooks the road) was definitely easier, but still quite steep, with large steps most of the way.”
“Easy parking and different options for a shorter or longer hike.”
“A perfect opportunity to enjoy the wonders of the rocky mountains.”
“To make a full loop head down Sanitas (either steeper/shorter route to the right/South from the meeting of the two trails or over the top of Sanitas mtn (North route down).”
“It was quite a popular trail for people and dogs alike, at least when walked on a sunny Saturday afternoon!”
“I didn't spy any fountains or restrooms along the way.”
“Trails can become hard to follow in certain areas so watch for the trail markers.”
