Lots of rolling up and downs. Path is well groomed but some of the hills are pretty intense

A fair number of elevation changes. One killer hill. Great views of Lafayette Reservoir and Mt Diablo. A shorter, paved path directly around the Reservoir is nice for a leisurely stroll.

Muddy in the rainy season so be prepared with the right shoes, but so beautiful and unpredictable in the right amount! It was a good work out too!! Started on the right side facing the reservoir, at 3:20pm and completed just at sunset.

Started on the right side

I love this run esp around sunrise or sunset. Pretty challenging with lovely views.

Dec-2017: This trail is awesome for hill and interval training. It is accurately moderate for the avid runner/hiker. The trail is dry, not too rocky. The views of the reservoir and surrounding hills are refreshing on a brisk sunrise hike. Not too many people early in the morning, especially along the upper rim, you’ll find you have the trail all to yourself. Except of course, the occasional fox will trot by or flock of turkeys making their parade. Definitely a great local trail to regularly visit.

Great hike with some moderately challenging slopes!

Great hike! Terrific views.

Decided to challenge myself after walking the Reservoir a few times. Gets a little slippery on the really steep parts, but totally doable for a newbie. Great views and easy trail to follow.

Great hike, a good combination of sun and shade, some good steep inclines, with flats and downward, pretty views of the reservoir.

Not for Mountain Bikes. Description needs to be updated here.

Some steep hills and not much shade so bring plenty of water. If you've done the reservoir loop and want more of a challenge this is for you. Great views of the reservoir and Mt Diablo.

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.

Always had a great work out here!! Love this trail.

It's a good workout 5mi 90min

this trail is beautiful. there is one brutal hill but no worries there is a bench at the top :). bring your water and have fun.
