One more steep climb up a few massive rock slabs followed (with plenty of cracks for hand and foot placements) before we arrived at the summit around 9am after a 5.5 hour ascent.
The summit is massive! I thought it might be a singular sharp point but there is loads of space to spread out and enjoy the view of Estes Park and the surrounding mountain ranges. After some snacks we started the long hike down. Everything below the Keyhole looked entirely different in the sun and we saw loads of hikers ascending both to the summit and to the lower Chasm Lake. I had torn a massive hole in my hiking pants sliding over some boulders on the descent so I had a half-assless-chaps-look going on.
In total the hike took us just under 10 hours, 14.5 miles, and 5,500 vertical feet.
