The 4 Peaks of Mt. Diablo - 16 miles (Grueling)

This is another hike that isn't feasible during the summer.

This is one of Mt. Diablo's premier hikes.  The views are fantastic!  As the name of the hike and the altitude gain suggests, there will be many ups and downs.  I can only take fit hikers with me.

Here are the peaks we get to do (in order):  Eagle Peak, Mt. Diablo Summit, North Peak, and Mt. Olympia.

Here is the link to a brochure and map of the State Park.

Duration: 7-8 hours

Length:  16 miles

Elevation gain:  5,000 ft

Facilities: at Mt. Diablo Summit

Dogs?: No

Water: Bring 2-3 liters.  You may refill at Mt. Diablo Summit.

Bring a snack/lunch.  We will have a break at one of the peaks.

Meeting Place: GPS: [masked],[masked]

Car pool location:

Petaluma-Lucky at the intersection of Lakeville and Caulfield Ln. Park closest to Payran St. suggested leave by 7:00

Come prepared to drive.  Riders should donate $8.  Please insist your driver accept the money. It's to cover more than gas money...it's the wear and tear on the vehicle. We like to take care of our drivers!

As always:

We combine enjoyment of the trail combined with respect for everyone’s time.   A steady pace and we just keep going!

Please always check your email the night before just in case there are any necessary adjustments.  This is especially important if there are any weather issues.  Cancellations due to weather will be posted by 10pm the previous evening.

Give yourself time to find the trail head so that you arrive prior to the scheduled time.  That is the time we head out on the trail.  We do NOT wait.  It would be disappointing to miss having you on the hike due to late arrival. 

See you on the trail!

    Biggest elevation I have done yet. And I did it! Thanks Yannick for giving me the chance to challenge myself. And yes, it was a challenge.

    Wow! What a great group! I'm so glad to have found hikers that can take this type of challenge in stride. I had a great time.

      will this be repeated again in Feb or March? or when the wild flowers come out? that would be a good time to do it.

    GPS lost power...However, using Google Earth, Estimated total distance 15.53 miles, elevation GAIN = 4279 feet.

    Now I can look over there and say, "hiked that".

      I went up on the Alamo side way back in 1986.

    Next time we need a hike with some more elevation! Unfortunately, the Grand Canyon is in Arizona! Great hike! Thanks again Yannick.

    Great hike, prettier than I expected. Every bit as grueling as I expected. Thanks all-

    Hi, I plan on driving. I'm coming from Santa Rosa, will be stopping at Petaluma (leaving by 7:00) and will go to Novato if you need me to, Christopher. Where in Novato? I plan on taking 37 from there.

    Hi Everyone,

    I was really looking forward to joining you tomorrow but canceled because I injured my foot. I was hoping it would be recovered by tomorrow but something tells me this ISN'T a hike to do injured. Can't wait for next time and ENJOY!

    Looking forward to it. I'm an experienced hiker, but this will be my first hike as a member of this Meetup group.

    Yannik, I am going to switch to a hike closer to home because I would be a carpooler. Thanks for organizing as always!

    Hello, I've never hiked with you before and was asked to mention a recent strenuous hike. I recently hiked to the top of Mt. St. Helena and ran a hilly half-marathon race. Looking forward to experiencing this challenge with other folks joining the hike.

    I suggest that we all meet at the Petaluma car-pool so that we arrive at the same time and no one needs to drive that long alone. I can either drive or ride. I have never been to mount diablo and do not own a GPS so if I drive I will need some help with directions. I can map quest the previous night but you know that sometimes it comes out weird.

  • Dese'

    Sounds like a goodie but will be still out of town. Have fun !

    October 26, 2013

  • Amy H.

    you know me, I am always up for a challenge! Petaluma car-pool for a long trip like this I could use the company I can drive or ride either way.

    Great idea for a trekking tour of Diablo, Yannick. Unfortunately it's a little more grueling than I want to take on. May I suggest that you lead the eight-mile waterfall loop in mid-April when the wildflowers are at their peak? The trail starts up Back Canyon (also at the end of Regency Drive) and returns down Donner Canyon.
