Hillside Wilderness Preserve trails

Monrovia, CA

Free

More than 4.5 miles of foothill trails with San Gabriel Valley views, reached from four neighborhood access points: Sleepy Hollow (off Norumbega Dr), Ridgeside, Cloverleaf and Highland Place. The trails are exposed, so go early on warm days and bring water. Park courteously, since the trailheads are on residential streets.
