Expect to do lots of scampering and bouldering. If you have hiking poles, I'd recommend bringing them. Great views from the top. From the trailhead, we took the left trail up (Mt Sanitas trail), and then came down along the East Ridge and Dakota Ridge trails. It would have been much more difficult to do the opposite. One of the more strenuous hikes I've done in this area.

Lovely hike but having put about 20 all trails hikes under our belts now this definitely clocks in as Hard, not moderate for us. Parking is challenging unless you're there really early. The elevation gain is persistent and on large steps, and if you head down the east ridge it has some really treacherous spots. Also, we found this trail "heavily" as opposed to moderately trafficked, usually with large groups who were quite loud and voices just echo heavily through the canyon on the way down. Nice workout close in but we'll probably stick with other hikes for the workout value.

Usually do the Mt Sanitas trail up & down, but today I tried out the Lion's Lair trail. Wanted to check out the suitability for when my grandsons visit. Good trail, about 4 miles rt with about 820' vertical gain from the parking at the hairpin turn. A milder, less crowded alternative to the "usual" south ridge.
