Season: All Year
DirectionsFrom Seattle, take Interstate 5 to Exit 95 south of Olympia. The exit ramp wraps around to Highway 121. Set your odometer to zero when you reach Hwy 121, then turn left (west) toward Littlerock. At 3.0 miles, pass through Littlerock, following signs to Capitol Forest. At 3.8 miles, reach a T and turn right. At 6.3 miles, just after entering Capitol Forest, pull into Margaret McKenny Campground on the left. Take note of a trail on the right immediately after entering, but proceed straight. Take the second left to find the day-use parking and equestrian staging area.
Just south of Puget Sound, Capitol Forest contains one of the most extensive trail systems in the region, and it's all open to mountain biking, much of it quite rigorous. The loose rocky trails, muddy bogs, and sharp hills on this ride demand a full supply of both stamina and riding skill.
But the beautiful lush forest and out-and-out adventure of it all make the hills seem more like minor nuisances than lung-busters. Like the Porter Creek loop, Mima Creek is located on the nonmotorized side of Capitol Forest. You won't be bothered by engines, but you will have to contend with trails chopped up and pureéd by horse hooves. Ride with care as hikers, runners, and equestrians use these trails extensively.
