Cathedral Spires trail, Colorado
A friend and I went to Cathedral Spires along the North Fork of the South Platte river. There are a lot of cool rock formations, and a LOT of lizards! This trail has some ridiculous elevation gain.
SOUTH PLATTE HOTEL
Down the road a bit, you can see the old South Platte Hotel. It is owned by Denver Water, and it looks like they might try to restore the structure in the near future.
