Highlight: 3NO3A - Horsethief Flat
Situated in the Big Bear area, just outside of Baldwin Lake, lays Horsethief Flat. This challenging off-road trail winds its way through the higher forest elevations,and down into a desert valley. The tall pine trees that paint the trail provide shade on a warm summer day and offer great picnic locations. The trail lets you experience what the area has to offer with a drastic change of landscape in a few short miles. This trail is a must do on a weekend wheeling trip to Big Bear. Or a day trip, the choice is yours!

Mapping Crew - California

A native Californian that has extensively traveled the Pacific Southwest, and now retired from an Engineering career with much time to spend off road. I enjoy off road travel exploring, and camping. Because I have the luxury of spending my days as I want, I am most interested in traveling overland and camping in dispersed sites. One thing I like about TrialsOffroad is the vast information about trails I have not traveled, and, to be able to set up a base camp and visit the nearby published trails. Thanks for the opportunity to be involved; I look forward to meeting many of you on the Trail.
