Located on the western side of Mare Island, this is a perfect trail for someone who prefers to take things easy. The 4-mile long level trail makes for an easy walk. As one strolls along the trail - one earns incredible views of Mt. Tamalpais, Mt. Diablo, the East Bay Hills, the Carquinez Strait, Napa Valley, and San Pablo Bay. Along the trail is a seasonal wetland filled with local shorebirds and waterfowl. There are pictured-signboards to guide you and explain some of the animals and plants in the area. I enjoy walking this trail because it's in my own back yard - plus, no dogs and bicycles are allowed. It makes walking easier because we don't to fear what we might step on.

Can't really hike this from the main road anymore, because they closed the parking area. So you have to drive to the back of the trail which is inside the hiddenbrooke community itself. Edit 6/12/2018: the trail is fairly overgrown and not maintained at this point. The trail is still hikeable, however you will be walking through tall dry grass and weeds for most of the trail. My legs got scratched up a bit. Spotted a snake wondering across the trail this time as well. Snakes are hard to see as the overgrowth obscures them fairly well. The first few hundred yards is cracked dry dirt that makes it easy to roll an ankle. I'm surprised this trail is this overgrown and not maintained given the money that is in that community. The trail is labeled at the trailhead. It is good for biking, horseback riding, and hiking. No dogs are allowed, however you will find nothing but dog shit on the main entryway for a good mile before it stops. The trail runs along some hills with constant incline and declines. However, it isn't all too difficult to hike. Half way through you will pass through a cattle walkway and enter the cow shit zone. There are patties everywhere. And you'll likely wander around some cows, but they scatter at first sight of you. The trail is clear for wearing shorts, however the ground isn't very flat as it is ravaged by cows on a daily basis.

There are some bushes that veer into the trail but it's not out of control, you can just work your way around it. Beware of dog poop, seems like no one picks up after their dog, EVER. It's a good trail to hike before work just as the sun is rising. It's short enough but still gives you a good cardio workout. I'll be back to finish the hike in it's entirety,

My favorite part was the tiny library at the entrance but the bad news is there was so much manure all along the trail that it was difficult to get around it.

It is tucked into the hills east of the Napa Valley. The country roads to get here are narrow and windy. Though a little tough to get to, what you will get in return is lack of crowds and serenity. Did a 5 mile loop here, which started with a climb up a hill through an oak lined trail. It climbs for about 25-30 minutes, and most parts are quite shady, so quite nice. Most of the views are just of the neighboring canyon landscape. You also may run into a few cows here and there. You also may run into pockets of bugs flying in clusters. This doesn't really *bug* me, but just FYI. On the descend is where you will run into the lake. The remaining part of the hike will now be flat, out in the sun but literally lake side. The blue from the sky and lake mirror off each other. A cool breeze often bounces off the lake to ease you from all the sun bathing you will be exposed to. But if you take out your earbuds for a while and just listen to the natural sounds here, (highly recommended), it will sedate you into a meditative state. This lake is so quiet, that you can hear the voices from the people on the boats, hundreds of yards away. It's crazy. So lots of bikes on this trail as well, especially this flat, lakeside part. So keep on the right side and be mindful on what's behind you at all times. And even though out in the cuts, you're still really only about 20 minutes away from restaurants/wineries of the Napa Valley.

As a local, this is one of my favorite places to spend time outdoors.

These paths are dog friendly which is a huge plus, and the trails are great for mountain bike riding! We've also kayaked as well and have come across fresh water otters that are so curious and love to follow your kayak. The absolute BEST time to come visit is in the spring when the grass is so green and all of the flowers are blooming. The water is usually very calm and there is a ton of wildlife to just sit and watch. It's one of the most scenic places in the valley, and it's so close to downtown St. Helena so after you can always go get lunch! Whether you're visiting or live in the valley, visit this gem!

HOWEVER I would highly suggest parking anywhere near the Waterfront/Marina rather than the actual River Park parking lot. So I originally parked near the sidewalk in front of the houses further down, but there were clearly a ton of break ins for the sidewalk parking as there was lots of broken glass. My GPS didn't take me directly to the River Park parking, but when I saw there were cars there I decided maybe I should move my car there instead. That ended up feeling like a bad idea as well as the parking lot is filled with tweakers and homeless people and the dude I parked next to was jacking off in his car. Aside from the unpleasant parking experience the actual trail is a nice for a walk. Once you pass the troll bridge near the marina it's not as packed as the waterfront so it'll be a little nice quiet walk near the water.
