Meet at 9:30 am at the Coldwater Lake boat launch parking lot, where the trailhead is located.  Take Exit 63 from I-5 onto State Route 505 through Toledo and turn left onto SR 504.

This is a chance to explore a generation old lake that's part of the Mt. St. Helens National Volcanic Monument.  A Northwest Forest Pass, or equivalent, must be displayed by each car at the trailhead.  Restrooms are located at the trailhead parking lot and at the one mile point on the trail.  We'll break for lunch at a sandy beach by the lake and return by the same route.
