This enormous (1,106,604 acres!) national forest sits in Colorado's Front Range, west of Colorado Springs.

Amateur mountaineers might want to challenge themselves against the famous Pikes Peak. There's a reason the view from the mountaintop inspired the classic "America the Beautiful!" It's a particularly tough hike at 13.5 miles of rugged terrain, though.

The convenient midpoint of Barr Camp lets you stop to rest, eat or sleep. Looking for a great view but not so great of a challenge? Drive partway up Pikes Peak Highway and snag the free shuttle to reach the summit.

Other major peaks in the forest include Mount Bierstadt and Mount Evans. All are among Colorado's 53 "fourteeners," peaks with elevations of 14,000 feet or more.

If slightly more leisurely exploration is your bag, definitely head into the Lost Creek Wilderness. A 27.6-mile loop trail takes you through gorgeous valleys and streams. Multiple campgrounds make it easy to turn this into an overnight adventure.

Experience celestial beauty while camping near the Garden of the Gods. With the orange glow of towering sandstone formations, it offers a heavenly escape for campers yearning for unforgettable views and soul-stirring sunsets.
