Visit four awesome national parks without the crowds

If you love visiting the national parks but hate the summer crowds, the August 2011 issue of Sunset Magazine suggests visiting these parks.

Capitol Reef is Utah's second largest national park, and has slot canyons, arches, cliffs, petroglyphs, a river flowing through a valley of 2,000 fruit trees, and 31 miles of trails to explore--and one-fifth of the visitors to the state's most popular national park, Zion.

You can camp--without hookups--at one of 71 shaded campsites along the river at Fruita Campground for $10.

Washington's North Cascades is known as the American Alps yet has only about 20,000 annual visitors. What you will find are 312 glaciers, 400 miles of hiking trails, and two mountain peaks that reach over 9,000 feet.

Watch peregrine falcons from atop 389-foot high Diablo Dam or hike to a back country fire tower with an awesome 360-degree views.

Camp at Colonial Creek Campground in an old growth forest at the base of glaciated Colonial Peak on the shore line of Diablo Lake for $12. No hookups, first come first served. Several other campgrounds lie along Route 20, the only highway through the park.

Sunset calls Great Basin the "quietest place on the planet." See 4,000 year-old bristlecone pines and drive most of the way up 13,065-foot Wheeler Peak for vies across Nevada and into Utah. Take Lexington Arch Trail to a six-story limestone arch.

Camp at 10,000-foot Wheeler Peak Campground--where you will feel the altitude--for $12.

No other canyon in North America has the dramatic vertical sheer 2,000 foot cliffs of  the Black Canyon of the Gunnison in Colorado. On the north rim you can take a 3-mile round-trip hike to the "jaw-dropping" panorama of Exclamation Point ot to Chasm View.

Camp at the amid the pinyons and junipers at North Rim campground for $12. No hook-ups and RVs over 35 feet not recommended (other campgrounds with full hook-ups are available). The 13 sites are first come first served and a Senior Pass will cut half off the fee.
