“An epic day covering all four of Chicago Basin's challenging 14ers.”— Tyler Prince
While portions of this run can easily be explored by fit dogs, the peaks above it are generally too technical for them.
Camping high in the basin is generally frowned upon. See Twin Lakes Approach for further information; camping along the end of Chicago Basin Trail is preferred.
Run up Twin Lakes Approach. From here, it's recommended you summit Sunlight and Windom first, as the rock on Sunlight is slightly more technical and prone to getting slippery. It's easier to escape from the Eolus Group should the weather change later in the day.
So, run Sunlight and Windom. Come back down to the Twin Lakes and run the Eolus Group. From here, all that's left is a descent back down Twin Lakes Approach.
