    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! :)

    Mount Sanitas and Lion's Lair Loop

    The Mount Sanitas and Lion's Lair Loop offers a diverse jogging experience, guiding you through serene ponderosa pine forests on the ascent via Lion's Lair Trail. As you climb, the scenery transitions to open views, culminating in breathtaking panoramic vistas from the Mount Sanitas summit, where you can spot the Flatirons and the Continental Divide. The descent, however, is a rugged affair, featuring steep, rocky sections that demand careful footing, making this a challenging yet rewarding route for those who love varied terrain.

    Planning your jog on this difficult 6.6-mile (10.7 km) loop, which typically takes around 1 hour and 38 minutes to complete with its 1412 feet (430 metres) of elevation gain, requires a few considerations. Access is generally from the Lion's Lair Trailhead. It's important to know that dogs are not allowed on the Lion's Lair Trail section, so leave your furry friends at home for this one. An early start is recommended to enjoy cooler temperatures and avoid crowds, especially if you're looking for less crowded jogging trails near Mount Sanitas.

    This loop is a fantastic alternative to the main Mount Sanitas trail, providing a less strenuous ascent while still delivering the iconic summit views. The forested Lion's Lair section offers welcome shade, making it a pleasant option on sunny days. Keep an eye out for local wildlife like Abert's squirrels, though be aware that black bears and mountain lions are also present in the area, adding to the wild feel of this popular route.
