The same weekend is the NW Mountain Challenge archery shoot at the Tamarack Ski Resort. If you're driving, throw in your bows and hit a course.
The lake has a lot of activities from paddle boarding to kayaking and boating. There are a couple of places to rent equipment if wanted.
McCall is a fun place and close to drive to.
There are tons of trails for hiking, mountain biking and four wheeling/dirt biking.
