Travel through the incredible alpine terrain of southern Rocky Mountain National Park in Colorado. This advanced peak challenge is based on the NPS's official map and includes all peaks lying south of US Highway 34 that are shown on the map. Includes the iconic 14er Longs Peak and many popular scrambles in the central region of the park. The majority of peaks in this challenge are off-trail over rough terrain and see far fewer visits than the ever-popular Longs. Despite being only a 90 min drive from Denver, you're likely to have many of these summits to yourself. A companion challenge to the Rocky Mountain National Park North Peak Challenge.

"The plan was just to do East and West Sisters, but after getting to the top we decided to bushwhack over to South Sister, which was a fun adventure for sure! Lots of scree surfing and scrambling always makes for a great day in the mountains!" - Twin Sisters Peak East, LGH-Dan, May 30, 2018
"A warm spring summit of Longs Peak Via the Loft Couloir and down the Keyhole.Overall the snow quality In the Loft was perfect. The backside and the Keyhole route however, were a completely different story. There was also plenty of post holing to be had in the boulder field below the Keyhole.It made for a very long day. My second summit of Longs Peak! " - Longs Peak, IanWright, May 16, 2018
"Flew in Wednesday night from Vegas. Got about 1.5 hours of sleep sitting straight up in the car at the trailhead, then started the hike at 1am. The only real issue we had on the way up was exhaustion due to the lack of sleep. We got rained on for the last few miles back to the trailhead. " - Longs Peak, Kevin, Aug 31, 2017
"3rd times a charm. After being snowed on at the keyhole in early September 3 years ago and rained out entirely last year, I finally had a great window of weather. Parking lot and first half mile of road was completely full when I arrived at 3am; I guess I started pretty late for this climb. Route after the keyhole is interesting. Ledges are fine, Trough is tedious, Narrows were intense, and the Homestretch was not as difficult as described. The huge flat summit of this peak is so unexpected after the variety in the route on the way up. Got hailed on for awhile on the way down, but otherw" - Longs Peak, edg, Aug 5, 2017
"Long approach. Alpine start at Wild Basin gate, hiked up to Sand Beach Lake, then scrambled up North Ridge and made final climb via east ridge shared with Pagoda. Descended opposite way towards Mt Alice. Considered summitting Alice too, but clouds were building and the hike is another 10 miles. Descended to Snowbank Lakes (beautiful) and double timed it out." - Chiefs Head Peak, NovaCatPeter, Jul 23, 2016
