Overview

      The Diablo 6-Peak Loop is a demanding 15-mile hike in Mount Diablo State Park, featuring steep ascents, diverse terrain, and breathtaking panoramic views across six scenic summits.

Description

      The Mount Diablo 5-Peak Loop is an epic adventure for avid hikers, offering a challenging and rewarding journey through some of the most stunning landscapes in the East Bay. This roughly 15-mile loop traverses five iconic peaks: Twin Peaks, Eagle Peak, Mount Diablo Summit, North Peak, and Mount Olympia. Along the way, hikers will experience a mix of rugged trails, sweeping vistas, and diverse ecosystems, from sun-drenched chaparral to shaded oak woodlands. The ascent to each peak provides breathtaking views of the surrounding valleys, the distant San Francisco skyline, and on clear days, even the Sierra Nevada.

      This loop is rated strenuous due to its significant elevation gain and varied terrain, but it’s a true bucket-list hike for those seeking a challenge. Each peak has its unique charm, from the peaceful quiet of Twin Peaks to the exhilarating 360-degree panorama atop Mount Diablo’s summit. The journey also offers plenty of opportunities to spot local wildlife, such as hawks soaring overhead or deer grazing along the trails. Whether you're a seasoned hiker or an adventurous spirit, this loop promises an unforgettable day of exploration and awe-inspiring natural beauty.

I got unlucky with the fog layer, but I am sure the ocean views are amazing if you happen to get there on a clear day. The elevation profile on this one is interesting, with multiple climbs to get to Rodeo Beach, and multiple climbs to come back to Muir Beach. There's a bunch of surfers over at the Rodeo Beach side. Trails are clean and well marked.

This is an amazing hike! Fantastic views over the various lakes in Desolation Wilderness. Also offers amazing views over Lake Tahoe and Emerald Bay. The scramble at the summit was fun! It looked worse than it actually was. It was cool to see a PCT through-hiker along the way. Trail is easy to follow and well maintained, with the exception of the summit.

This hike is amazing! Starting off at the desert floor and rising all the way through 4 (I think) different ecosystems with different wildlife, plants, and trees. 10k feet of elevation gain is substantial, but it was surprisingly not that difficult. Exciting hikes like this tend to get my mind wandering instead of paying attention to how much I am suffering. The gondola ride down was a bit scarier than I anticipated. That thing gets moving!

Very scenic ocean views and some views of the San Francisco skyline, with the Golden Gate poking over the hills. Relatively easy hike. Well maintained trail that is mostly concrete. Some cool ruins of the old military batteries. There's actually some legitimately great graffiti at the summit.

The trail is well maintained and starts off very green, and opens up to some rolling hills with views over San Francisco and the surrounding area. You can see Mt. Tamalpais and the Marin Headlands fairly well. The summit is rather boring, but the views behind the summit make up for it.

For being fairly short, the incline is pretty dang good! Very green with turkeys wandering around. The summit is fairly well forested, so the views of the bay are glimpses through the tree-line. Great little hike though! Parking is limited and on a residential dead-end street.

This is a good little short leg burner. I specifically start down in a residential neighborhood and it makes the hike a little longer and adds some incline. This is a very popular tourist destination and it offers arguably the best views over San Francisco. TONS of people at the summit - as you can also just drive up there. Great little urban hike.

The views here are incredible! It is a very popular hiking location with a decent size parking lot that absolutely gets filled up as the day progresses. Get there early! The summit is somewhat bland, but the rest of the hike makes up for it.

Great views and a good little incline hike to train at elevation with. At almost 11,500' elevation it gets the lungs working a bit more than usual. Trail is decently maintained, but there's a section that requires a few ganders at the GPS track to make sure you are on the correct route. Great hike! Plenty of parking.

This is where I saw my first black bear while hiking! It was ahead of me crossing the trail about 100 yards away. It didn't even look over at me as it kept walking up the mountain side. Boy did my heart skip a beat! It is fascinating to see these monsters roaming around in their natural habitat. Saw a handful of trail runners along the hike, but it was overall fairly quiet as far as traffic is concerned. Fantastic views over Lake Tahoe at a distance.

The summit offers stunning views over Desolation Wilderness and South Lake Tahoe and all the other surrounding peaks. Don't let the short distance fool you! This hike is a rigorous uphill hike from the start to the summit. A lot of it has burn scars from the previous fire that went through.

This hike is amazing! Hiking just to Flagpole peak is rather short - adding in Echo Peak makes it substantially longer and offers even better views of Desolation Wilderness and Lake Tahoe. The hike up to Flagpole peak requires some minimal scrambling, but it isn't anything too challenging.

This is right in my backyard! I have hiked this (and the full length of the Bay Area Ridge Trail) many many times. It can get ticky at times - but it wasn't in February. The hills are still green! This will change as the summer rolls through. Well maintained trail. Easy to follow.

Ah! Mission Peak! This is a VERY popular trail - but luckily the trail is wide for the majority of the hike. This loop is much better than the typical out-and-back from Ohlone College. I have hiked it a plethora of times. Still a good amount of incline for the distance. Definitely gets the calves working!
