This big, almost 40 mile, loop will circumnavigate Chula Vista. It can be ridden either direction; however consideration to the northeastern "corner" of the loop should be factored as the steepest terrain will be encountered on Mother Miguel Mtn. The overall ride would be considered a GREEN trail; however with the addition of this mountain section and the overall length of the ride consider the effort of the loop BLUE. Prepare to tackle the mountain section or opt to shorten the ride and avoid it entirely by taking streets or trails that bypass it. Just know that if you skip the climb then you'll miss out on the best views of the region. That said there are a number of alternate routes a rider could take to achieve the loop especially near the Otay Lakes, Sweetwater Reservoir and in the Otay Valley - exploration is encouraged. The western "side" of the loop is busy and industrial - watch for traffic.
