Skiing & Snowshoeing
In winter, only the southern entrance road to Rim Village is kept plowed to provide access to several Nordic skiing trails. Rentals are unavailable inside the park, so bring skis with you. Only experienced skiers should attempt the dangerous, avalanche-prone loop around Crater Lake, which takes two to three days and requires a backcountry permit from park headquarters.
Snowshoes are provided for free ranger-led snowshoe walks, which are held at 1pm on weekends from Thanksgiving through March or April; call 541-594-3100 for reservations.
Crater Lake has over 90 miles of hiking trails, though some higher ones aren't completely clear of snow until late July. From the eastern edge of the Rim Village parking lot, a 1.7-mile trail leads up 8054ft Garfield Peak to an expansive view of the lake; in July the slopes are covered with wildflowers. A strenuous 5-mile round-trip hike takes you to an even better lake vista atop 8929ft Mt Scott, the highest point in the park. For a steep but shorter hike, trek up 0.7 miles to the Watchman, an old lookout tower on the opposite side of the lake that boasts one of the park's best views. For flower enthusiasts, there's an easy 1-mile nature trail near the Steel Visitors Center that winds through the Castle Crest Wildflower Garden Trail.
The popular and steep mile-long Cleetwood Cove Trail, at the northern end of the crater, provides the only water access at the cove. Two-hour boat tours are available; reserve, as these are popular.
