Breathtaking. That's the word for the Colorado National Monument. Here you'll find sheer walled red rock canyons, big blue skies and panoramic views, as well as bighorn sheep and golden eagles. Rangers recommend the 23-mile Rim Rock Drive, which takes visitors to campgrounds, hiking trails and "remote canyons full of bird song and solitude."

Cedar Breaks National Monument is closed from October through late May because of heavy snowfall, but the rest of the year, it's a stellar place to visit, and views of the spectacular 3-mile long, 2,000-foot-deep, naturally occurring "amphitheater" are available all year long.

The old-growth coastal redwood forest just outside Mill Valley is cool and shady year-round. The refreshing climate attracts visitors and an annual migration of Convergent Ladybugs seeking refuge from the hot Central Valley. Visitors to the forest, which is named after conservationist John Muir, can participate in monthly beach cleanups or hike among the giant trees (the tallest recorded redwood is 379.1 feet, about the height of a 35-story building.) Muir Woods is about 16 miles north of San Francisco. Temperatures average range from 40 to 70 degrees, with rain between November and April.
