Is climbing the Longs Peak Keyhole Route worth it? For me, the amazing views and challenging terrain were very much worth the effort. I love a challenge. However, if you have the faintest bit of vertigo or aren’t acclimated to being at altitude then you will probably want to sit this one out. If you do want to attempt climbing Longs Peak, I highly recommend overnighting in the Boulder Field. I think it makes the summit much more achievable than a long day hike.
