Crater Lake is Oregon’s only national park, home to the deepest lake in the United States (1,943 ft). The park is dramatic and underrated — about 700,000 visitors per year, far fewer than Olympic or Yellowstone. Rates run $165 to $235 per night before fees. The camping window is short — Mazama Campground typically opens late May and closes mid-October.

Crater Lake-specific considerations
- Camping season is short — generally late May through mid-October. Plan accordingly.
- Elevation. Rim is 7,100 ft. Cold nights even in summer (40s°F).
- Snow possible any month at the rim.
- Rim Drive closures for snow can persist into June. Confirm before travel.
- Wizard Island boat access requires reservations and the 600 ft Cleetwood Cove trail descent.
- Cellular coverage very limited in the park.
- Wildfire smoke can affect late-summer visibility.
- No swimming in the lake (it’s a closed ecosystem). Day-trip experience only.
- Lost Creek opens later than Mazama and has stricter length limits.
