Great mountain and city views, lovely little stream, oaks The trail starts out on the Chumash Trail moving steadily upward for 2.6 miles with interesting rock formations, great views of the city, and somewhat barren hillsides, the result of a fire a few years ago. Bear left at the junction with Rocky peak fire road and follow the ridge line for 1.5 miles to a connector trail to the Las Llajas Trail, Look for fossils after you crest the top of the grade. Head down Las Llajas canyon, with a nice little creek to your left and an occasional cluster of oaks to shade your way. The Las Llajas trail terminates on Evening Sky Drive. Go left on Evening Star until it dead ends, then go through the gate to a short connector trail the leads back to the Chumash Trailhead. Keep a heads up for mountain bikers flying down the trail on this hike!

Nice trail, well maintained. Recommend counterclockwise to do the steep part first. Lots of flowers right now. Be careful for the mountain bikers.

This is a great long loop hike. But if you take it counter clockwise you get a more intense workout.

First half is a nice steady incline, but other half is boring steady decline on a fire road. Good hike if you'd like something with decent mileage, but still want to go out and party later in the evening. Little-to-no shade.

Update 7/2/19: hit it again w daypack (2L in reservoir, used 1.5L), this time starting Las Llajas TH, sunny 90F, no wind. Really enjoyed uphill thru the oak tree-filled ranch area this go around, a terrific testosterone jostling burn. Stats: 9.38 mi, 2hr27min, 1460 cal, 145 avg BPM (91-177 range). Be safe. Dr J.

Hiked on 6/29/19. Stats: 3 hrs, 10.42 mi, 1536 cal, 89-165 BPM. Started 1030am up Chumash, warm day (90F). Had 1L of water in reservoir, which fortunately was enough to last me to the start of the pavement leading up to Las Llajas trailhead. Overall, not a rigorous hike, but a long one (and as other reports note, one with little sunshade), with a mix of hard and soft track; so for sunny days at least, def not a route for the heat exhaustion prone. Amazing vistas along the way, especially when you come upon and pass the big (and rather forlorn) felled oak. For the adventurous (for me, discovered courtesy of faulty beta pried at the summit from a fellow hiker, who pointed down the objectionable path, excitedly exclaiming: "It's the way to Las Llajas!"), I took a 1 mile detour on an old overgrown fire road (now a barely accessible single track) at the top of the Las Llajas junction (near what looks like a large circular stone cairn); anyway I came across some fabulous rock formations and a slew of fossilized stones that together appear not to have been touched in some time. Overall: highly recommend. Be safe. Dr J.

Very difficult and hot hike during a sunny day. Not much shade. Not for beginners. Did a total of 13.0 miles on this hike because if you start at flannagan chumash trail you will hit a sign that says 2.7 miles to flannagan and if you tail it right it take you to rocky peak mountain for anyones claiming.

Gradual incline. Good path. Gets hard. No shade in the summer. Muddy path in winter.

Nice trail for 80+ degree weather! Shaded and very scenic. Only went 2.5 miles given timeframe after work and daylight. Definitely want to go back!

Nice 9 mile loop. I started on Las Llajas and ended with the Chumash Trail. Las Llajas is a smooth fire road while Chumash is a technical single track so plenty of variety plus great views.

I went on this hike to find the steam shovel. I asked a lot of people and no one knew what I was talking about when I would stop them to ask for directions, but thanks to a group of people that I ran into. They knew exactly where it was at and told me how to get there. From the beginning you hike 2.7 miles. So about 700 feet after you cross the creek for the 3rd time. Right at 2.7 you will see a small trail that is 12 inches wide on the left. Take that up for 1.8 and make sure to take water because that 1.8 is all incline, but it is not too bad. A kid can do it and so can a dog or you can even mountain bike it.

starts off easy if you are going clockwise, but about 3 miles in it gets tough.

This is a great 9.51 mile hike up into the mountains. I went on a monday around Noon and I saw 2 people the entire hike outside of the park and neighborhood where you start. This loop is really 3 different sections. The first part is a partly paved/partly dirt road with a slight incline. The 2nd part is the same dirt road but a much steeper incline to the top of the mountains. Total elevation on my hike was 1,796ft. The 3rd part is a narrow rocky trail down the south side of the mountains at a steep decline. According to my apple watch it took me 3hrs and 7mins and I exerted 1,110 calories to complete the hike. For most of the hike you can't see any buildings, feels like you're much further away from the city than you are.

Fantastic trail! I was there after recent rains so there were small water falls everywhere. Very green! Muddy trail in spots. I had to hop several streams. Trail leads up for several miles with spectacular views on top. Large road leads back down by the runoff stream for several miles. Definitely will come back.

It's weird that this trail is rated Hard when Chumash is rated moderate and that is the most difficult aspect . The actual Las Llajas trail is a very wide fireroad of moderate incline. You'll approach a fork in the road about 3.5 miles in. To the left is private property so you must head to the right up the semi paved road. This is where the trail starts a steeper ascent. Still a wide fireroad up until you connect to Rocky Peak. Scenery is quite nice and affords views of the Santa Clarita valley.

There is more to this trail than just the loop! I did the steam shovel hike. 1.5 hour hike to steam shovel. 1.5 miles back. 3 hours total. Look for shells on the mountain! Bring lots of water! The view at the top is amazing! How did that steam shovel get up there???!!! Careful not to turn an ankle on loose rocks. Someone should mark the tiny trail that takes you up the mountain! It's a hard trail to find if you have never been there before. Leave before sunset or you will be walking home in the dark!!!
