A beautiful place to see wildlife and nature. We saw cows, heard woodpeckers, and saw a variety of wildflowers. It was easy to get lost if you want to follow one trail. I would advise just going down one to see where it goes!

HikingGreat!

Nice loop trail with beautiful views! Parts are rocky and steep- would rate this trail as moderate. Bring cash or a card, they charge a per person permit fee ($3 for adults), not sure how often they check. Beautiful park with many trails, we will be back.

Beautiful! Nice to see so many native wildflowers and relatively few invasive. The oaks and manzanita were stunning against a bright blue sky this time of year. However, I would not call this an easy trail-at least between the 1.3 and 1.7 mile marks. We had to slide on our bottoms to get down several places. My friend has a new knee and it was tricky. My phone tracked it at closer to 3.2 miles.

Absolutely beautiful this time of year. Get there in the morning so it’s not crowded. Easy hike and very enjoyable. Very dog and family friendly.

It’s a beautiful trail in the spring time when it’s green! Good beginning hiking trail... the lake and pond is pretty much dried up but there is still so many mini trails you could take around. There is a daily fee.

It’s a great trail, it is just literally so dry. The pond and most of the lake have dried up. It’s rather sad to actually see the effects of climate change first hand.

Went out with my 5, 7 and 12 year olds. Hike was easy enough. Hard part was climbing up to the cave and then back down. Took us some time and there were some scared tears shed but we made it down safe and sound and the adventure was everything. The lake is more of a pond right now. We could see how at some point it had been much fuller. We made a lot of stops to rest and take pictures. Took us a couple hours but like I said we made a lot of stops. There are many different trails and this app helped keep us on track. There are signs but it can get confusing.

There’s a park fee at a meter in the parking lot. Daily use for a person with a dog was $4 I believe. They take cash and card. Just keep the receipt with you and an id while on the trails. There’s signs posted for a portion of this trail that’s closed for people with dogs. The sign says that the area near the lake is closed for sheep grazing season and those who violate will be ticketed by park rangers who are actively out on the main trail in the park in white trucks. For some parts of this trail, unless you have this app open the entire time, it’s easy to go off of the highlighted trail at least for me it was. Gorgeous views at the top of the incline and the cows on the trail are docile and curious. Kind of freaked me out seeing one so close without fencing. There’s signs at the beginning of the trail that explain how to interact with the wildlife.

Great, beautiful hike for family.. trail a little tricky to figure out. Only complaint is many mountain bikers making it a bit treacherous with kids and dog

Great for trail running, great for kids and dogs. The outer quarry trails are very shaded, even midday, but the sound of a busy road kind of ruins the aesthetic. It takes about a mile of hiking in before the traffic noise abates. My 4 year old loves the zigzagging and overlapping trails here. We hiked down to the “lake” which is a pond as of beginning of November. The inner trails are mostly paved. Only met 3 people in 5 hours on a weekday. I would go again!
