Perhaps one of the toughest hikes in the San Fernando Valley, this trail can be used as a training course for harder hikes (such as Mt. Whitney or Cactus-to-Clouds). The sharp elevation gain is recommended only for experienced hikers. For those who endure the challenge, you will be rewarded with some of the best views in the valley. Be sure to bring plenty of water...and even more willpower.
Went last night around 5:30 and did the loop. The first 1.5 miles is like being on a stair master for an hour. My legs were burning the entire time. Once you get up to the radio towers, it evens out a bit and the scenery is great. The downhill is a nice reprieve but then your legs start burning again from constant downhill. The views at sunset are spectacular so it was well worth the hard work. Not a lot of other hikers on the trail, but numerous lizards and wildlife after the sun goes down (saw an excited skunk and a coyote). If you park near the playground, there are bathrooms. Bring lots of water and avoid in the middle of the day because it's hot and hardly any shade. We did the counterclockwise route so we hiked UP the steepest part. Hiking clockwise and DOWN the steepest part looks like it could be quite treacherous without the right shoes and potentially hiking poles.
If you're looking for a good incline workout, this is a great option. Light traffic and beautiful scenery. Only downside is your in the sun the whole time so Around sun down is the best time to go.
