An intense dayhike or moderate backpack in the Cucamonga Wilderness. This hike hits two of the tallest, most prominent peaks in the Angeles National Forest. Beginning with the historic, alpine brook that runs through Icehouse Canyon, this trail climbs through picturesque pine and cedar to Icehouse Saddle before visiting the site of an old trail resort and ascending a long ridge between the two peaks. A truly magnificent and rewarding hike, with great views of the Baldy Bowl for almost the entire route. Highly, highly recommended.

Went for an overnight and the view from the top is amazing. We found a nice spot towards Ontario peak and it was incredible, will go again soon

Late start ... so only made it to Onterio Peak (did not want to finish up in the dark). I really like the hike up to the saddle. ... no matter the season. It is a good hike and the views and surroundings are great. Then it was kind of boring until I reached Onterio Peak.

I find this hike hard ... but not challenging (unless it is done in the snow). I also clocked in 13.7 miles (but I did park a bit down from the trail head ... but I also did not hike to Big Horn Peak).

I hike with my dog (the little 7.5# dog in hiking gear). We love seeing other dogs out there. Both on and off leash ... dogs are well behaved and owners are responsible.

Did this on Saturday the 30th. The weather was perfect. I went up using the Chapman trail as it is a little longer and more secluded. I did both Ontario and Big Horn peaks. I had around 30/35 ounces of water and drank it all. I met a few nice people, drank my bottle of beer after using the bottle opener at Ontario peak(it's mounted on the tree) and saw couple big horn sheep.

I did Ontario Peak (without Big Horn Peak) on a beautiful mid-'70s day. After doing Cucamonga Peak last month, I'd say it's about the same difficulty as Ontario. Ontario (without Big Horn) has about 400 feet less elevation gain, but it's a mile longer. If you do it with Big Horn, it's harder than Cucamonga. Make sure to bring extra water (I brought 3 liters and had some left at the end).

Hiking for operation on target. Flashing from peak to peak. Great accomplishment. Didn't see any bighorns. Met a lot of friendly people along the way.

This was a fun, long hike. Admittedly we set out to do both Ontario and Big Horn Peak, but we were ready to descend after Ontario. Judging by the recordings other members posted, this seems to be the trend.
The views were absolutely beautiful, similar to Cucamonga but not as steep to get there. After you get to the saddle, the trail gets narrow and fuzzy in some spots. I counted 14 fallen trees you have to climb or straddle over on the way up to Ontario. Def recommend following the map from Alltrails on your phone.
Keep your voices down like we did to see bighorn sheep, deer, and blue-tailed skinks!

This is a challenging hike and I highly recommend it. I normally hike to the peak in the winter season which is both beautiful and dangerous–twice I've been caught in storms on the way down. With the right equipment and good company this trip will be memorable and make great stories for the years to come.

All the way sunshine and a little bit shade. My face was sunburnt and my right ankle was twisted and hurt. My team player gave me a great deal of courage and accompanied me to complete a round trip. I need a comfort hiking boot and a lightweight backpack for next Saturday Mt. Wilson trail hiking. At last, I felt exhausted but encouraged and was present with friendship.

Great set of peaks they've got there. I did these two and Cucamonga in one punishing day. See my recording 3 trails, 1 day. Super hard. Stunning views and lots of people. Big Horn seemed to be the one the fewest folks went out to. It was hot and tiring. Bring more water than you think you need, as none is available at the Kelly Camp.

Nice stream at the beginning, small trickles running across the trail, lot of shade for 2/3 of the hike. the last 1.5 miles is open so bring sun protection. That last stretch is longer than you think, don't get fooled by the false summits! we took it slow with a long rest at the peak and it took 8 hours.
