It’s a decent quick hike through the state park. There is a $5 fee for parking. You only get good views for less than half of the trail. Otherwise your just hiking amongst the brush. There were a few deep muddy spots on the sidewinder trail.

I really enjoyed the trail! There were plenty of the the yellow wildflowers (like the whole trail), lupines, and a few patches of poppies. There were a few muddy spots, but they all had convenient sticks to help cross over. The trail itself is very well maintained until about a mile in, and it gets SUPER narrow for the rest of the trail. We kept following it, and it loops back around. There’s a side trail labeled “sidewinder” and that’s where we came out of the loop! It was a great adventure!

Easy scenic trail, but once you got to the loop, it was a bit overgrown and we had to just lower the head and plow through a bit. My 4 year old thought it was fun, had to go on my shoulders for a bit during overgrown portions, 7 year old made it all the way through on her own. Definitely pay the $5 to park inside the park, long ways just to get to the trail.

This review is for sidewinder and raptor trails. Too overgrown. I don’t mind a tight trail but this was so overgrown had to keep arms out front just to part the grasses and the wild mustard. Tripped over the gnarled grasses etc for at least 4 of the 5 miles we walked. The trail had a rut that u either had to straddle or walk toe to heel most of the time. It did have some beautiful views and saw no one else which was nice but I’m sure there were better trails we could and should have walked.

I would rate this trail easy. Some parts are muddy. Flower bloom not as much as some would think. There is a patch of poppies at the end of the loop. Still very pretty for a easy short hike.

Everything’s been pretty dead this year since there hasn’t been much rain. It’s a nice easy walk but not much scenery

Fun but I would do for a while. The brush was over 6 feet tall and had to mash through cause was already committed and a lot of bees. Beautiful scenery though.

This trail is beautiful to hike during the wildflower season. Since we haven't had a lot of rains, the trail itself is dry, without much color. It's a decent hike and there are nice vistas at some of the high points. No shade at all, so go early or on days that won't get as hot.

Overall it was a nice place to walk in nature with my dog. I was a bit sad to not have seen more colors in the plants ( it was mostly dead), but it was still pretty. It's unfortunate that you have to pay for parking ($5) but the price is not bad.

Gorgeous hike despite the overgrown dried shrubs that blocked us from making the loop to Sidewinder Trail.

Many trails are overgrown due to lack of maintenance, short staffed. Bring lots of water and snacks and don't panic when you reach a dead end due to overgrown trails you can't get through. Grab a map too so you can call the ranger if you get in trouble.
