The trail was difficult to follow, went off path several times but eventually found our way

Great views of Las Trampas and the 680 corridor from Wall Point ridge. Went counter clockwise. Took the 1/2 mile single track trail from live oak campground to wall point trail which goes under Sentinel Rock. Solid elevation gain in 7 miles. Consider hiking early morning or late evening in the summer

This trail was just OK in my opinion. She’s steep, make sure to wear proper shoes. Beginning and end had some good views (golden hills) but most of the trail was just in the bushes. Started at the end of the day around 4 PM, saw 1 coyote about 3 ft off trail. Overall, was good exercise, but wont be aching to do it again.

Great trail but I would have gotten lost without the GPS map because there are a lot of intersecting trails. Beautiful views from Sentinel Rock.

I had fun on this one! Bring extra extra water though; I found myself rationing my water since it was so hot and dry out. A park ranger also warned me about water, he said a couple had to be rescued due to exhaustion and lack of water. The trail gets narrow at times, fyi. I hardly ran into anyone on a Wednesday evening. Once you’re 2/3 of the way, it gets beautiful! I heard a pack of coyotes not too far away, but was glad not to see any mountain lions..

The parking fee was $6 when we visited today. This is a great hike! My best friend and I did this as an evening hike and saw a beautiful sunset and a lot of wildlife, including coyotes and deer. The views from Twin Peaks were amazing–you could see all the way out to Suisun Bay! A couple warnings though: • Some areas of the Eagle Peak Trail part of the loop had eroded quite a bit • There were several areas that required an easy rock scramble during the final ascent to Twin Peaks • Parking is $6 • The length of the loop is closer to 4 miles than indicated here

Running

Great Trail! I have ran for 4 hours 38 minutes + 40 minutes breaks and pictures :-). Make sure you have at least 2 liters of water with you and you need to add another 2 liters at the top of Mount Diablo. You can also have water at the end of the trail if you stopped at Mitchel Rock. I left from Clayton and started clockwise as it seemed less dangerous to climb The Peaks in that direction. The other way around (as presented), has lot of rocks going down. Be very careful but so beautiful. Enjoy!

The gravel on the uphills/downhills made it hard but overall, it was a great hike! Bring plenty of water, sunblock. And try not to hit a biker on the way up/down.

Hiking

One of my regular training segments. Starting off it’s a gradual gain of elevation in the first 2 Miles followed by a a lot more gain. Good news is it makes for a fast decent. Usually takes me about 90 mins up and 55 mins down. Keep in mind it’s about 6.75 miles to the Summit and about 3300 elevation gain. So, if you are hiking and not running it will take about 2- 3 hrs to the Summit if you are able to maintain a 18-20 min pace . Start early as some spots are extremely exposed.

Our first time to hike with my family. Real good rock formations but has lots of graffiti. We got off track because there’s lots of trails even though we used the recording. My family enjoyed the hike immensely. Just watch out for poison oak. The road going up here is winding and not for the faint hearted if you’re scared of heights specially sharing it with bikers.

Go early in the day in the summer. Great trail for all abilities. A few tough hills. Beautiful trail in the flat shady part by the dry creeks.

HikingFeeNo shade

Great Views - But not much shade. The lower and upper portions are wide but there's a single file section about the middle 1/3rd. Bring plenty of water. Pretty steady climb the whole way up. A moderate trail cause it's not too long and the grade isn't too steep. Not many people except for the last 1/2 mile at the top. One rest room along the way. Parking cost $10 for the day - Self registration. OK to park if you're completely off pavement and if you pay the fee and put the tag in your window.

I think I liked this trail? I liked the general area but have no idea if I was technically on the trail or not. The rock outcroppings were cool though.

A truly special loop in Diablo! Most of the trails are single track, but I didn’t run into any people except for at the parking lot. Today’s hike was temperate out, but the park is dry and many parts are exposed, so you’ll want to bring ample water. There’s a place to fill up at the top of Diablo and I definitely took advantage. There’s a lot of up and down and it’s a great challenge. You’ll definitely enjoy this loop tour of the park!

Mostly great. Some difficulties in figuring out where the trail actually went. Lots of ecological variety. Great views throughout. About half of the trail is quite sunny--on a hot day, be sure to bring a lot of water.

An ass kicker for sure! Bring plenty of water, narrow for half the trail
