...as a friend described the trails on Blue Diamond Hill. Hiked this one solo, starting from the trailhead by the corrals. I took the Rock Garden Trail, above Echo Canyon, to the upper part of the Fossil Trail. Here I followed a Jeep Trail for a bit (might have been one of the Gypsum roads, I found out later (oops)), and located two high points. One had a wind sock at the top and two park benches below it. Incredible views of Las Vegas and Red Rock. I followed the bike trails across Overlook Ridge and then down into Skull Canyon for the descent. It was about a 7 mile loop.
Nice easy to follow trail to the top.
