The best camping in Oregon.

Much of the Pacific Northwest's most impressive geology can be found in beautiful Oregon. The powerful Columbia River flows dramatically through the Cascade Mountains in the north, creating a natural border with Washington State in the process. Hit the Columbia River Gorge National Scenic Area for campgrounds and hiking trails along the river.

Located in south-central Oregon, Crater Lake National Park hosts the deepest lake in the United States. For a real visual treat, head to the Hells Canyon National Recreation Area near the Idaho border. The titular canyon drops over 8,000 feet to the Snake River, making it the deepest river gorge in North America. Wildlife spotting opportunities abound in the surrounding recreational area, so bring your binoculars!

Speaking of wildlife, the world's largest mushroom—a honey fungus that covers nearly two and a half miles—lives here.

This state has a few quirks that might surprise you on a first visit. If you're driving through the state, keep in mind that Oregon has no self-serve gas stations. Attendants pump your gas every time you fuel up. The state's also an outlier when it comes to taxation—it's one of only five states that has no sales tax.
