Between October 1 and May 31 when snow dep is 2 feet or more, crosscountry parties may include up to 12 people. At Paradise only , party size is unlimited when the snow is at least 2 feet deep, but parties of more than 12 people must camp within easy walking distance of the 24-hour restrooms. For more on winter camping, call or write for information. Alpine Camping Alpine zones provide climbing and alpine hikers opportunities in areas above treeline, generally above 6,000 feet, or elsewhere on exposed rock, glaciers, and snowfields. Camping is permitted only on permanent snow or ice or on bare ground areas previously used as campsite.
Alpine plants depend on the shelter for rocks to survive.
Of particular concern is the area within the boundaries of the Muir snowfield between Pebble Creek and Anvil Rock. Group size is limited to 12 for camping on snow and ice, and five for bare ground areas. Expect fallen trees across many trails. Boil or otherwise treat all water before drinking. Mount Rainier trails have much exposed rock and tree roots which may be slippery.
