Things to See & Do in Oregon
Oregon Caves National Monument
Oregon Caves National Monument is small in size, 480 acres, but rich in diversity. Above ground, the monument encompasses a remnant old-growth coniferous forest. It harbors a fantastic array of plants, and a Douglas-fir tree with the widest known girth in Oregon. Three hiking trails access this forest. Below ground is an active marble cave created by natural forces over hundreds of thousands of years in one of the world's most diverse geologic realms. The park service provides cave tours for a fee. Located near Caves Junction, Oregon.
California National Historic Trail
The California Trail carried over 250,000 gold-seekers and farmers to the gold fields and rich farmlands of California during the 1840's and 1850's, the greatest mass migration in American history. Today, more than 1,000 miles of trail ruts and traces can still be seen in the vast undeveloped lands between Casper Wyoming and the West Coast, reminders of the sacrifices, struggles, and triumphs of early American travelers and settlers. More than 240 historic sites along the trail will eventually be available for public use and interpretation. The trail passes through the states of Missouri, Kansas, Nebraska, Colorado, Wyoming, Idaho, Utah, Nevada, Oregon, and California.
Crater Lake National Park
Crater Lake is widely known for its intense blue color and spectacular views. During summer, visitors may navigate the Rim Drive around the lake, enjoy boat tours on the lake surface, stay in the historic Crater Lake Lodge, camp at Mazama Village, or hike some of the park's various trails including Mt. Scott at 8,929 ft. Diverse interpretive programs enhance visitors' knowledge and appreciation of this national park, 90% of which is managed as wilderness. The winter brings some of the heaviest snowfall in the country, averaging 533 inches per year. Although park facilities mostly close for this snowy season, visitors may view the lake during fair weather, enjoy cross-country skiing, and participate in weekend snowshoe hikes.
