The Bark Park where we start the run is in Calabasas, about 10 minutes from Malibu Creek State Park on Las Virgenes. The smooth Bark Park Trail of singletrack meets with the Millenium Trail Loop, and the keyhole is 14 miles total. After taking the 1.2 mile initial trail from the trailhead, we turn right on the New Millenium Loop.
There is NO water on the course or at the start, bring at least two 20oz bottles, preferably a hydration pack if you plan on completing the entire loop. This is considered a hard loop. There is a lot of elevation to gain, come prepared!
Take the Las Virgenes Road. Exit off the 101, head south, and park on the parking lot at the Bark Park, entrance on the left side of the road. There's a singletrack that heads up from the northern end of the dog park; this is the trailhead. If you are driving from Malibu State Park turn right on Los Virgenes and look for the Bark Park on your right.
There is also plenty parking across the street at the school parking lot in case the Bark Park parking is full.
