My fiancé and I plus our three dogs completed this trail from the trailhead all the way through to Scout Lake by Jefferson Park. This trail took us 10 hours to complete round-trip, with about a 30 minute stop at Scout Lake and 30 minutes for lunch. It wasn't too hot of a day, but it was warm, and the trail was very rocky, which isn't bad going up, but coming down was a little rough. Uphill the ENTIRE time there. Plenty of creeks, but almost no shade. Great views though!
