Lime Creek is the last decent and reliable water source if you hike the Colorado Trail southbound. There is a nicely shaded spot to take a break and filter the water. Campspots are not too easy to find here though.

Deer Creek is a mostly peaceful, flowy and fun trail. However, once you get to this last section (in the downhill direction), you will find that the difficulty drastically changes. The descent suddenly includes very tight corners on steep terrain. It is great fun if you are able to tackle the technical challenges, but is also something to keep in mind for less daring bikers, as this is an unavoidable section of the trail.

This is a fun and long trail which extends north and south beyond this section between its intersections with Coal Creek and Engine Creek Trails. The northern part is more technical, while the southern one is considered to be the more fun one. The views are beautiful and the trail is easily accessed via multiple entry points.
