Denver's local hikes include Green Mountain, Deer Mountain, Mount Falcon, Table Mountain and White Ranch. Castlewood Canyon is a more mellow excursion that tours a miniature canyon system that includes a shady forest and plenty of wildlife viewing opportunities. Less than an hour from town, real mountain hikes await. The 14,000 foot peaks of Grays and Torreys are classic summer hikes, while Grizzly Peak, Mount Sniktau, Mount Parnassus and Mount Edwards are all 13,000 ft. summits that are in the same area. And if you're not aiming to get up a summit, areas such as Herman Gulch, Watrous Gulch, and St. Marys Glacier are all fun spots to visit for a day out in the wilderness. And finally, all of Boulder's great hikes -- from the flat Marshall Mesa to the high point of the city at South Boulder Peak -- are a little over a half hour away from Denver. Denver's hiking season is year round, so there's always somewhere to visit.
