“This loop makes for a good workout with great views.”— Eric Hong
Electric Mountain Bikes Allowed
Family Friendly The wide fire road and pretty scenery of the park is family friendly. Be sure to pick the right route and distance to fit the age of the riders.
Need to Know
Another possible alternative and slightly longer route is through the Castillero Trail south of the Mine Hill Rd. That's about one more mile through the loop. That will also lead you to the highest peak in the park on the Castillero Trail slightly south of the Bull Run. It is marked with a fire hose stand.
Often deer are near the trail and sometimes bobcats, mountain lions, rattlesnakes, and turkeys. Mountain lions won't bother people, and the rattlesnakes are mellow unless pissed off.
There are some interesting old mines on the April Trail which is a small loop off this route and at the Cristobol Mine adjacent to Mine Hill Trail.
The trails can be a bit crowded on beautiful spring weekends.
