I think this is a tough walk; there are 4 serious hills. With that being said, I LOVE that we have this so near us to do.

Great, challenging hike with very steep inclines. Exposed, not much shade around the Rim Trail. Not sure why this says no dogs - dogs are allowed all throughout the Lafayette Reservoir area but just must be on a leash.

I run/hike the rim all the time because it's so darn convenient. It backs up to a neighborhoods a majority of the time, so it doesn't feel like a hike proper, but it's my go-to place as it's close to home. The steepest hill is rough from either direction... long with kinder grades (trailhead near parking lot entrance) v. short & *steep* to the peak (trailhead near lot exit). The view of Mt. Diablo & Briones are lovely + there are usually turkey & deer out in the evening :) I run it in about 65-70 min & hike it with 8lb pack in about 95 min. Adding the sunset trail (the 0.4 area not included on trail map) gives you a little more hill. You can also take trails down to the shore trail and back up again, adding miles and a change of scenery... there are five altogether, three of which are marked.
