1. Trailhead (0 mi)
The trailhead starts off relatively flat with a large area to meet up with others, and maybe air down just for the comfort level. There is also a dispersed campsite a few hundred feet up the trail on the left.

Q: I took this route today. It offered great scenery. However, it seemed to start at 6S13 and then became 5S15 when I took the first left as described in the route (not the 17 mile to Hemet route). Does 6S13 overlap with 5S15?

Mapping Crew - California and Idaho

Dennis Clark was born in Los Angeles in 1942 and after 76 years of living in So Cal he moved to Emmett, Idaho with his wife Patricia, has four adult children with many grand and great grandchildren. He has loved the outdoors since his Cub Scout and Boy Scout days while camping with the family. He's an archer, hunter and fisherman but no longer wishes to harm animals. He has been involved with photography since the 1960's. He became more of a serious hiker in 2010 when he started Geocaching and has hiked the three tallest peaks in So Cal, Mt San Jacinto, Mt San Gorgonio and Mt Baldy, along with most of the lesser peaks in search of caches. Geocaching started his love for the USFS Trail system as he used the trails frequently to get to certain trailheads. He had a 2002 Ford Ranger 2wd and its amazing where that little pickup took him. In 5 years of weekly geocaching he was only stuck once in some Palm Springs sand. His 2016 Wrangler Sport Unlimited was purchased in 2015. He has become quite lazy in the hiking department as he can now drive to most locations. He's looking forward to posting some trails and don't hesitate to ask him for any help you might need.
