The higher you get the more you are exposed to the sun. Some tree cover in the beginning and at the top. Mostly rocky terrain. A little windy on top.

This is a very beautiful trial that is pretty easy, and I highly recommend it for a nice day hike with some friends. This trial is not too heavily trafficked, beautiful views almost the whole entire trail. Make sure you take the short detour to visit the peak of Mt. Islip!

Not often you can still hike this trail in mid Dec without winter gears. Nice patches of clouds in blue sky. Our group of 6 owned the trail for AM. Very pleasant day and place. Hit the trail while weather is not cold yet

Nice trail, a little windy (hence the name), lots of people doing maintenance.

Perfect trail with stunning views. Very well marked. On a cloudy day 2/3 of the hike you’ll be hiking above the clouds; watching clouds constantly move and change shapes is oddly satisfying. Super cold at the top of Mt. Islip so be prepared!- bring a jacket and a hat. Definitely coming back.

Very nice trail run to Mt. Islip ascending Big Cienega and descending Windy Gap. The gradient is not too steep, usually not too rocky, and definitely not crowded on a weekday. Started at 830 am and it was about 20 degrees cooler than than the hot temperatures down in Azusa and the San Gabriel Valley. GPS measured the full loop just short of 8 miles, including the side trip to the summit of Mt. Islip. I ascended in 45:59 from Windy Gap Trailhead at Crystal Lake to Mt. Islip, a record according to (although I did it in 43:08 many years ago in the pre-Strava era). Other trail runners typically take over an hour for the ascent even without walking at all. Saw 2 deer on the descent, and only one hiker. The hiker had 2 unleashed dogs and one immediately lunged at me when I approached; it bit my leg (calf) and bloodied it up! PLEASE, dogs should be on a leash as the trailhead sign says.

Surprisingly rewarding. Saw a small bear on the road, people were talking selfies. The bear was dark brown with a lighter brown snout. I got mountain scared that the mom would show up. I went around the bear, which jumped a rail into the forest. The hike was choice, I did it clockwise, but the earlier hikers got shade doing it regular. Yes, very little shade, and in July you get those smoggy layered views of the basin. I will definitely do this again, super mellow yet as challenging as you can handle.

It was a great hike... I always love going to the Crystal Lake Cafe when I am done with a hike in that area. Be warned that there were a TON of fallen rocks on the trail. I really regretted wearing my running shoes and not my hiking boots. I could feel every rock and I slipped a few times, so just come prepared. Also, go early on hot days... a lot of the trail is not shaded. Gorgeous views from the top. Also, we got caught in a ladybug swarm, which was kind of awesome.

Loved every twist, turned and elevation. The view is amazing. It was amazing getting back and look up on how high we went. What a day to spend Mothers Day.

If you're looking for up, up and up this is a good place to start. This is the other way to get to Little Jimmy campground and we did it at night. When we came back through after camping we saw beautiful views and some fire ravaged areas. Many pairs of eyes looking at us from the dark and some weren't scared of us (don't know what was watching us)!!! Also saw deer.

We only did Crystal Lake to Windy Gap. Originally we had planned to go to Islip, but we barely made it to windy gap, as we werent prepared for that much snow. Great views hiking up this side of the windy gap, more enjoyable than hiking up the north facing side from lil jimmy. Although a lot of snow had melted by the time we went down, it was still tough trekking. Would be great to hike up this side again in the spring.

Adventure pass is needed for parking. There's a good amount of shade throughout the hike trail. A must need is bug repellent spray. Thankfully I always carry some because we definitely needed it. There are a lot of mosquitos and gnats, especially in the beginning. Bring more than enough water just in case! The scenery is definitely worth the hike. The trail is somewhat marked and signs are far and few. This is also a very lightly trafficked and narrow trail. Definitely will be coming back.

Great trail! All the way up to Windy Gap and along the Islip ridge until we could come down Big Cienaga for a total of 9 miles. Great views all the way around. A good amount of tree coverage throughout. We will definitely be back to check out other trails in the area.

Hiked portions of this trail for a backpacking trip to Little Jimmy with a Boy Scout troop. Trail was mostly shaded in the morning, and the views from the peak were amazing. Definitely stop by and get some spring water from the Little Jimmy spring, it's delicious!

The trail was a bit tough with a full pack, but a great time was had all around.

Very nice views when going to the top. Still lots of burned areas from the fire in 2002. Really nice and only saw 4 people the entire hike.

This is a moderate hike. Only passed one person on the whole trail. So beautiful and no trash! No shade and saw a snake and deer. Would do it again. When you try to find the trail, take the road to the lake and follow it to the first parking lot. Park there and the trail is south/west of the parking lot.

Steady and easy hike...but definitely worth it. Went in early April did the windy gap trail from west side up and looped back to east side down..most people do the other way around. I loved the scenery it is truly one of the nicest hikes in the San Gabriel mountains. This is a great intermediate to beginner (at least with some conditioning) hike that will surely please! Awesome!
