Trailhead parking/camping area for Mount Saint Helens Worm Flow climb

This is the standard camping spot for the Mount Saint Helens winter climbing route, the Worm Flow route. Many cross-contry skis trails also can be accessed from it. 

There are two large parking lots suitable for cars, trailers and RVs.  People also camp in tents in the parking lot or adjacent forest area. There is a warming hut (open Dec-March) and 2 vaulted toilets. An overflow parking lot is also found immediately below the main loop.

No cell reception (AT&T). Can be busy and noisy with many vehicles and snowmobiles during the day but it is the only place to camp for an alpine start to climb/ski Mount Saint Helens.
