Mt Islip is a 4.2 mile out and back trail located near Valyermo, California and is good for all skill levels. The trail is primarily used for hiking, horses, and mountain biking and is accessible from June until November. Dogs and horses are also able to use this trail.
Vast mountain vistas, lovely pine forest, mid-hike picnic spot The views to the south from the summit of Mt Islip are nothing short of stunning. You can see Crystal Lake, the front range of the San Gabriels, as well as the San Gabriel river canyon. I had my lunch looking at this vista and felt like I was in heaven. The hike starts out heading up a forest service road for a half mile, then you head left at the signed trailhead to Little Jimmy Camp, one mile ahead. I really like the gently rolling, pine shaded trail into Little Jimmy Camp. The less ambitious in your group can relax in the camp (it has rest rooms and a spring a 1/4 mile away), while the balance of your group heads up to the summit. The summit trail is at the back of Little Jimmy camp (walk past both rest rooms). The summit trail takes you up some switch backs to a ridgeline. There is a junction with another trail at the ridgeline that comes up from Crystal Lake, but you should stay on the ridgeline trail up to the summit.
Ive hiked Mt Islip about 4 times now during summer and winter. Ive done it 2 times from the Islip Saddle (which is the saddle on the angeles crest highway) and done it twice from the Crystal Lake Recreational center. IMO the crystal lake approach is waaay better than the islip saddle area. Elevation gain from crystal lake is 2,450 ft and 6.6 rt miles. Elevation gain from Islip saddle is about 1,500 ft and 7 miles rt. This is a great hike it's essentially a lower elevated version of Mt Baden Powell. During the winter you can expect a lot of snow on the northern side of Islip since its shaded, so be sure to take crampons and hiking poles as there are several spots on the trail were slipping can be easy to do. Overall good hike above 8,000 ft.
Great view at the end of the trail. Be aware of the high elevation! Bring water!
This was a good change of scenery. The dramatic views are unbeatable. There are multiple trails leading to the top of Mt. Islip coming from a few different directions.
it was a beautiful trail little hard to figure out at some points, almost did the whole thing but kids started giving out on me towards the end.
Went from the Crest Highway PCT entrance but it basically leads to the same trail. Not very hard and the trail is well maintained. The view at the top was pretty good and the cabin is something cool to see.
Views are spectacular from the summit. Moderate hike but worth the effort.
This is very nice trail.I would rank the difficulty as moderate. Lots of shaded area.
Short but gives you a good workout.
I hesitate even reviewing this trail. Mt Islip and CLJ are one favorite Los Angeles based hikes and campgrounds.
Part of the PCT Mt Islip is a section of trail offers views, wildlife, plant life and different environments as you trek. This trail is rated moderate in difficulty however it is the elevation that may be more of an obstacle for some who are not use to it. Take your time up the mountain where you will be rewarded with views looking over primarily LA & OC counties and stretching past Catalina Island. A top of Islip is also an old cabin built in the twenties that is still standing.
The hike is approximately 3.5 to 4.5 hours and approximately 6+ miles. Plan on carving out 8 hours with drive time from LA area.
- Most of this hike is on the north face of the mountain. Plan accordingly.
- Water available at LJS.
A beautiful secluded hike starting off from Angeles Crest highway, mile marker 66.37. This is the easiest way to Mount Islip and I Took the trail ( Pacific Crest Trail) vs the Fire Road. There are 3 options to Get to Mount Islip and Crystal lake to Windy Gap is a must for all Southern California hikers. This is great elevation training and the views from Windy Gap and the Peak are some of the best. Video of my adventure is posted below.
A fairly scenic trail for a pleasant day hike to bag another San Gabriel summit. This one seemed a bit more strenuous than the trail to the summit of nearby Throop Peak I had also done recently. The first mile of trail is moderately steep for my 50 year old butt, but then it levels out for the next mile or so to the Little Jimmy camp site. From there you have about another mile to the summit, and this section of the trail also has its moderately steep parts. Awesome views down into the Crystal Lake basin as you climb towards the summit.
This was a nice hike from the Angeles Crest HWY. Decent elevation gain and a great view once you get to the top. These is an old stone home used by the forestry service when the tower was still standing. Well worth it, make it an overnighter by backpacking to Little Jimy.
Mt. Islip was awesome, my buddies and I hiked it after the snow storm, hiking in the snow with the sun on your back. Took my cam and tripod was not disappointed at all. In my top 25 list of SoCal.
I added a couple of pics "trail with snow"
