About this permit
The Snow Zone is the largest allocation in the Enchantment Permit Area: USFS issues five groups per day to it, against four for Stuart, three each for Colchuck and Eightmile/Caroline, and 24 people per day for the Core Zone. A group can be up to eight people.
USFS describes the zone as the Snow Lakes and Nada Lake basin plus the Snow Creek drainage, mostly forested, and more forgiving to campers in bad weather than the other permit zones, while still holding views of the surrounding peaks. The trail climbs steadily for 6.5 miles from the Snow Lakes Trailhead, gaining 4,100 feet.
The zone touches the Core. Beyond Snow Lakes the trail ascends steeply over granite slabs another 1,400 feet to Lake Viviane, which is in the Core Zone. A Snow Zone permit lets you day hike the whole Core basin; it does not let you camp above Upper Snow Lake, and there are no established campsites between Upper Snow and Viviane anyway.
The route
USFS puts it plainly: the trail climbs steadily for 6.5 miles from the Snow Lakes Trailhead, gaining 4,100 feet. That is the whole approach, and it is the reason this zone stays the easiest to draw.
Beyond Snow Lakes the trail turns primitive, ascending steeply over granite slabs another 1,400 feet to Lake Viviane, which is inside the Core Zone. Groups with a Snow Zone permit are welcome to day hike throughout the Core Zone but must camp at or below Upper Snow Lake. USFS notes there are no established campsites between Upper Snow and Lake Viviane, so the boundary is also a practical one.
Why it matters
The Enchantments get treated as one permit. They are not: USFS splits them five ways, and the Snow Zone takes five groups a day, more than any other. It is also the forgiving one. USFS describes the Snow Zone as mostly forested and more sheltered in bad weather than the other zones, which matters in a place where June and September routinely deliver winter.
The feeling
This is the long way in. Six and a half miles of steady climbing through forest with the Snow Creek drainage below you, and then the basin opens onto Nada and the Snow Lakes with the same rugged peaks the Core Zone gets, seen from underneath.
