9:30 am sharp at Ape Canyon Trailhead. Please be on time. The group will leave at 9:45 whether all participants have arrived or not. From Woodland, take Lewis River Road (SR 503) east for 32 miles. Continue east on FR 90 for 3.2 miles, then veer left on FR 83 and proceed 11.2 miles to the trailhead. Each car will need a NW Forest service pass.

This hike is slightly exposed and shared with mountain bikes. You should be able to maintain a 2 MPH pace uphill. I like to take breaks and long lunches. We will hike the pace of the slowest member. 

If there is more than 50% chance of rain forcasted we will move to an alternative 9.4 mile trip with 200 feet of elevation gain along Coldwater Lake Trail.

Since this is a Halloween hike, feel free to wear a festive mask or costume you can hike in.
