Henry Hagg Lake is 1,200- acre reservoir nestled in the foothills of the Coastal Range, just went of Forest Grove, where you can enjoy swimming, fishing, canoeing and waterskiing (there are two boat launches) or picnicking along the shore. Surrounding Scoggins Valley Park offers 13 miles of biking and hiking trails, where you can take in the scenery, observe a variety of birds, or encounter a deer. The Park also has an 18-hole disc golf course.
For bicyclers, do not forget to visit one of the three Bike Hubs at the park welcome center, Elks Recreation Area and Boat Ramp.
