"Decided to go wild on a day with nothing to do. Initially planned to hit South Boulder, Bear, and Nebel Horn, but a side trail to an unknown summit (I guess the high point of the Dakota Hogbacks) enticed me to one additional summit, while the Nebel Horn summit proved enticingly just out of reach: there was one final class 5 move just below the west side of the summit (like, less than 10 feet) that was a bit too exposed for my taste. In retrospect, I'm pretty sure I approached from the wrong side, and the approach from the East is supposed to remain class 4. Aside from that, it was a really great day." — wazoheat • Nov 7, 2021

"This mountain can be summited several ways. From trails that start down in Boulder, several parking areas along Flafstaff Rd or a super easy loop which starts near the summit at the Ute trail. Warm day, heavy smoke, lots of wild flowers. " — Mtstalker • Aug 30, 2021
"Excellent day. Went from the airport to the trail head. Not too many people on the trail , went up the backside Lions Lair trail, trail is in great shape and easy to navigate. Of course, I took the wrong trail about 1/2 mile on the way down , but I needed the exercise so it was a win win . " — puddlepirate • Aug 26, 2021
"Went on a long trek to get a good view of the ongoing Calwoods Fire. I figured Sanitas would be crowded so I tried Anemone first, but the fire was behind the ridge from the top of Anemone (which I should have known), so I went to Sanitas anyway up the less-crowded Lions Head trail. The views were epic and frightening; it sure was a sight I won't forget. Visited the summit rock of Dakota Ridge on the way back because I hadn't been in a while and it wasn't far out of the way." — wazoheat • Oct 17, 2020
