Very cool hike. Waterfall is impressive And. An be seen by several vantages as wells as enjoyed close up with a bit of bouldering. Zero cover so sunscreen is essential. Hiked maybe half a dozen times and only found one tick so... take that for what you will. Lots of water if you want to bring a filter instead of carrying extra liters. Salamanders everywhere one visit. Rattlesnakes occasionally. Turkey and deer every time. To get to the falls, you stay right when approaching then there’s a mark on the trail to exit left to the creek. This area is especially prime for snakes but a vigilant step is all that’s required.

Lovely place. Been here many times. Hiked in on Saturday June 6, 2020. Creek and falls are completely bone dry. Still beautiful, as today was a cool 75, after a stint of 104 weather. Brown ticks out in force! Spray your clothing with appropriate repellent. Two ticks on my daughter's clothing (shirt and pants). Two on me, one started to try to dig into my knee on the ride home! Clearly missed him in our spot checks before leaving. Two awesome gopher snakes, one with a recent bulge from the local Chipotle.

May 10, 2020. Unfortunately, The waterfall was just a trickle but we still enjoyed the walk. It’s pretty flat for the most part until you get within a couple miles from the falls. We clocked over 8 miles round trip. There was no shade so we’re glad we started at 6am! We saw a lot of snakes as well. Bring water and sunscreen!

The drive to this trail was lovely aside from the potholes you have to dodge. The trail itself is for the most part easy. the moderate part is towards the end where it inclines and switch backs. It is also steep heading off the main trail to the waterfall. You will have to scramble a good amount to get to the waterfall pool. Unfortunately some a**holes were motorbiking up and down the hillsides shredding the earth and turning up the delicate wildflowers. Someone called the Sheriff who we came across the Sheriff on the way back but they were long gone. Even though my service said 4g it was pretty much zero service.

Love this hike. The drive in is just as fun and relaxing as the trail. The path is wide, easy to follow, and mostly flat for majority of the hike, still easy if you’re out of shape like me lol. You have to cross the stream about 10 times but the water was low enough that I never got my feet wet. Waterfall is really nice and pretty easy to get right down to the bottom of. Super secluded, only ever seen one other person there at a time. No shade so bring a hat and sunscreen!

Great hike, most of which is very flat with a wide, well groomed trail that frequently crosses the creek. Bring waterproof shoes! Not a whole lot of shade either. Waterfall was very secluded. There was a pull out directly across from the gate for parking. I went in the morning and only came across 2 ppl on the way out. I used the path directions from the last review which was helpful!

Excellent hike. Been up to the falls a couple of times over the years. If you are going and plan to come from the Napa/Fairfield/Winters side look for mile marker 23.75 on the road. It is just after that where there is a pull out on the right. It's not marked. The entrance way is on the other side of the street. If you are going to the base of the falls....hike up the flat section for about 3+ miles. Once the canyon starts to narrow, you will come to a red painted rock. Go right up the hill on the road. If you go straight it will dead end. Once you go up the road there is another fork a couple of hundreds yards up.....go left. Do not go to the top of the mountain via the road as there really isn't a way to get to the falls....about a mile up from the red rock you will see (to your left) a series of paths going straight down the hill pointed directly to the falls. You can go this way or keep going for another 1/4 mile and you will come to a stone arrow marker in the road pointing left. Take this one. Follow this down the hill and it will meander to the base of the falls. Enjoy!

First try I couldn't find the way to the water fall.. Ended up getting tired. So I tried again a few weeks later. This time I found the way to the water fall.. Beautiful and worth the hike. It's a long walk but once you start climbing the hill towards the end and see zim zim it makes it worth it.

Star thistle has really taken over since I last hiked this trail in 2011 and I had to stop to pull some thorns out of my dogs’ paws. Easy hike overall and the falls are beautiful.

1.11.2020 Great trail as always. The river was down, so no problem with any of the crosses! Waterfall was beautiful. Plants are just starting to pop up and we even saw a California Newt.

Nice area. You can stick to the dirt roads or wander off onto game trails. You can camp overnight if you're more than 1/4 mile from the entrances. Definitely going back to explore more.

Creek was dry. Trail had lots of thistle that was irritating my dog's paws so we turned back about 1 mile in.

Awesome hike! Fairly easy! There are 9 creek crossings total. The only downfall is the amount of ticks in this area

As of today, aug 12, 2018. Not amazing at all. Smokey, dry, way too hot and literally looks like it burned down yesterday. Very sketchy to get to and should not go by yourself. Hopefully in the cooler months and growth from rain I’ll try again but def bummed bc recent reviews said it was great. ......... also I was just informed that it’s hunting season up there. Def not safe right now!!!!

The point of doing this 12.9 kilometer is to reach the Zim Zim water fall in Napa. The trail is fine, i crossed the creek 11-12 times as i hiked. the scenery wasnt that impressive i saw pipes many times and to me this ruins the beauty of nature. The trail branches as you get closer to the waterfall. If you go left, prepare yourself for serious bushwhacking. I got pulled, pushed, scratched, poked, poked in the eye, i scrambled, i climbed, i screamed to no use. i couldnt find the trail to the waterfall, the bushes,the rising water, and the wobbly rocks stubbornly blocked access to the waterfall. Fearing that darkness will soon descend and i would be stuck on a boulder with no way back or forwarded, i declared defeat and retreated. I took the second path leading up the waterfall and managed to see it from above. Not the same experience but i will be back with some backup. The drive to the waterfall was not easy, snaking road that can get you dizzy. Closer to the beginning of the trail, the road got really bumpy. Many holes so watch out. Also if the water level of the creek gets high, it floods the road. Not this year though, very minimal flooding, the road is passable

This trail is remote! The first part of the trail I would classify as easy. Towards the waterfall, I would classify as moderate. We met two guys hunting coyotes about 1.25 miles in. They were very nice. Lots of birds. We flushed out a whole bunch of what we call grouse on the east coast.

Nice hike with decent incline at the end and pretty views but it is not worth the amount of ticks! I found 8 ticks on myself and almost 30 on my dog.

This was a beautiful hike and the waterfall was amazing but I'm going to give a few warnings… Do not bring a dog, my dog came home with 20+ ticks - add to the fact that it's not great for humans either as I came home with 1 and the person with me came home with 4, then there is the shade issue… As there is not any, so if you're going to take this hike take as much water as you can carry, and last there's the peril of the end stretch to the Falls… It is very steep and very slippery because of the dead wheatgrass so take it very slow and make sure you have some good traction on your shoes!

Lovely hike with beautiful wild flowers and a gorgeous waterfall at the end. Some tips that I want to emphasize: - Driving northbound on Knoxville rd, you drive through 3 streams that may be impassible during high water. The first 2 I passed, the crossings were dry, but there was water flowing across the 3rd stream (low enough to drive through on a small coupe) - Lots of stream crossings on the actual hike itself so be prepared for wet feet, whether you are wearing waterproof boots or not. Met a lady there that crossed all the streams barefoot. - When you get to the pink/red rock I HIGHLY recommend taking the trail on the right. There will be another fork in the trail, if you take the left turn it will take you to the waterfall which is absolutely beautiful. Taking the main trail (or right turn) will take you to an overview/outlook of the waterfall and you can choose to do a longer hike/loop. IF you decide to take the straight/left trail at the pink rock, be prepared to do some bushwacking as there is no trail. We tried to take that trail, but it leads to nothing and is pretty sketchy. Enter at your own risk. - Be wary of ticks on this trail. I found a tick on myself and another in my car after getting home.
