Heavy mountain bike use on weekends.
Amazing park with long gradual rolling hills. Very impressed to feel deep within the forrest while being so close to town.
Favorite place to mountain bike.
Beautiful trail lots of rocks and mountain bikes on the trails.
Been all over the trail system but not in one big loop
Side note: Highly recommend taking tick precautions at this park. Nymphs of the species that carries Lyme Disease here have the highest rate rate of infection of all tested parks in Sonoma County: 2008-2014 averaged >7% infection rate (>8% in 2013 the last single year data available today). Adults are lower @ 2.6% for 2008-2014. See Marin Sonoma Mosquito Vector Control for data & more info. http://msmosquito.com/programs-services/labsurveillance-program/tick-surveillance

It was a nice hike. And although the trails were marked well, I did a loop twice. It had rained pretty steady the day before hiking so, there were streams going down the trail. It was shallow enough to hike up the middle of it and not get wet for the most part. Even though it was wet, it wasn't slippery. I hiked 6.88 miles in 2 hours and didn't hit all the trails. There are s lot of people using the trail, but it doesn't seem crowded.
It's 10 minutes from my house. Awesome.
