This trail is not a trail for beginners. If you are a beginner, do not ride this trail. Skidding your way down the trail is not riding the trail. This destroys the trail.

Please do not avoid the trail obstacles. The erosion on the trail is largely due to users creating new ways for water to flow down the trail.

It is rated Double Black due to relative difficulty to other JMP blue trails, and the fact that this trail is JMP's bone breaker, especially with clipped riders.

Fast, steep and natural trail; usually ridden downhill. Central rocky stretch requires good line choice and is black diamond when not rutted; lots of railroad ties cut in and eroded; short travel bikes can get quickly overwhelmed. Fun and short and the roughest trail in the park.


April 2022 Note: Updated to Double Black due to several recent broken leg injuries.

      seemed fine to me, rocked my new hardtail down it and honestly enjoyed it more than Cindy.

       Chaparral was good today. Dry conditions, but always fun to run down those rock faces and’s step downs. Hikers were friendly too.

       Best tech trail in the park! Tons of challenges that will test your skills. The rock garden is stellar!

       Rode yesterday, still pretty Smokey but clear and cool in the morning. Recommend wearing protective gear

       Not sure how this turned into a double black but my 10 yo can clean this with little issues and the only part that gives me some double thoughts is the rock garden in the middle where line choice matters. Definitely a solid black when combining the Rock garden and all the log drops. Definitely rideable for intermediate on up. Good practice for other places such as Rockville and annadel.

       No more than 18 inches. Erosion can change that although.

       This has been a single black forever and certainly only deserves a single black rating. Don’t know why the rating changed to double. Even if riding blind, go slow, pick your line and you’ll be fine. My gf who’s been riding once a month for only 6 months cleans this trail

       Visiting the park from the north shore. So far this is the best trail in the park. Speed is your friend for sure! Would not call it a double black tho.

       The double black rating is to discourage non-technical riders from getting injured which has happened on this trail. It is also arguably one of the most, if not the most, technical mapped trails in the East Bay.

       i think "cake is a lie" and "sulfur springs (the las trampas one)" are significantly more difficult then chaparral.

      juanroberts BTCEB (May 24, 2022 at 17:45)
       That is your opinion. I respect that. Nevertheless, I am going to share some facts, and my opinion to help provide a broader understanding.

      The "cake is a lie" trail is not on California's trail map of the Mount Diablo area: www.parks.ca.gov/pages/517/files/mtdiablobrochure.pdf

      The Sulfur Springs trail is not mentioned on the EBRPD's list of trails, not even under its "Advanced" heading:

      It could be because Sulfur Springs Trail on EBRPD's map outright shows it as a hiker- and horse-only trail:

      So those two trails are not mapped, or are not mapped for cycling.

      In terms of Chaparral, the difficulty designation is not only based on one person's ability to ride down its so-called waterfall drops on a good day. It also considers a blind corner with overhead logs, and the changing condition because of loose rocks, deadfallen trees, poison oak, erosion, and other aspects that can compound its difficulty. At the same time, consider it is a trail popular with hikers and even families because it is located in a small city park. Put all this together, and the last thing you want is for a rider to get hurt or to endanger others because of a lack of skill.

      Here is another factor in terms of determining the difficulty of a trail. Chaparral Trail has two-way traffic. At dusk when there are less people around, riding up Chaparral Trail without dabbing, bunny hopping, or stopping, in my opinion, is harder than on any other trail in Joaquin Miller Park.

      Most importantly, there have been calls for emergency crews to do extractions of injured riders out of this particular trail, and they were not necessarily beginner riders. The number of past injuries can be considered a primary factor in determining difficulty. Sometimes we are lucky on a ride, and sometimes we are not. Chaparral Trail tends to have more bad luck because it just does not flow like others trails in Joaquin Miller Park.

      Thank you.

       Pretty rowdy right now. Between the dry dusty conditions now and the ruts from the rain late last year it’s definitely a wild ride. Definitely a downhill trail - if someone can ride UP this I will give them serious kudos
