Great trail!! Although it was a cloudy day and I couldn't see the views, the trail itself was worth it. Definitely a thigh burner. I'm 5'8", 135lbs and a regular runner/hiker and it took me about an hour to cover just one mile so it's a workout!
Access to the trailhead is a little confusing per the guide on this site. If you pass the metal gate and hike about a quarter of a mile on the gravel road, just as you enter the woods you will see a big sign clearly marking the Mailbox Peak Trailhead. It gives all kinds of ominous cautions about the difficulty of the trail. On a cloudy day if your alone one can almost hear the Jaws them in the background. From there, the trail is marked all the way with white reflectors so even though there are parts of the trail that are unclear, one cannot lose their way if you follow the markers.
Enjoy the many wildflowers on the last scramble to the top, but don't get so distracted that you trip. The trail is very rocky and on the hike back down, I actually saw a guy trip and role about 20 feet so it does happen.
Good luck, have fun and bring a jacket for the top!
