🏔 Wilderness
Spray Park Backcountry Camp (Mt. Rainier NP)
About This Permit
Spray Park is Mt. Rainier's most spectacular wildflower meadow — a broad subalpine basin at 6,400 feet where lupine, paintbrush, and bistort bloom against the backdrop of the massive Rainier ice fields in July and early August. The backcountry camp here is one of the most coveted wilderness permits in the park. The 8-mile round trip from Mowich Lake is strenuous but the payoff is otherworldly.
Frequently Asked Questions
When is the best time to visit Spray Park?
Peak wildflower season is typically mid-July through early August. Snow lingers late — the trail may be impassable in early July some years. Check the NPS Mt. Rainier trail conditions page before booking.
How do I get a Spray Park wilderness permit?
Wilderness permits for Mt. Rainier backcountry camps are issued on recreation.gov. A portion of permits are reserved in advance starting in mid-March; a walk-up quota (30%) is released at the Wilderness Information Center the morning before your trip. Spray Park is among the most competitive of all Rainier camps.
Is the Mowich Lake road accessible by car?
Mowich Lake Road (WA-165) is unpaved for the last ~10 miles and can be rough. High-clearance vehicles are recommended but most passenger cars manage it in dry conditions. The road typically opens by late June and closes after the first major snowfall (usually October).
