No Dogs... This trail is described as dog friendly, but upon arrival (after a 40 minute drive) there were signs that said No Pets allowed in the water shed. We left. Lame.

This trail is not dog friendly.

It was a nice and easy hike with the kids with lots of shade. It’s also good for jogging.

Overall a nice trail, but just too much horse poop

Pleasant trail for a longer walk. Trails are wide enough to keep distance from other people. Not to many people overall. Parking is actually open and quite sufficient.

Overall a good easy hike! Most of the scenery is forest trails. It was well maintained with occasional horse poop on the pathway.

Everything was incredibly verdant today, it makes me feel like spring might actually be coming! You can tell that a lot of trees came down after the storm, but they had been removed from the trail. kudos to the maintenance crew. My waterproof boots proved once again that they don't work as promised as I splashed through a few flooded parts of the trail and squished through the mud. I had a Great Wok without seeing another soul, not too surprising considering the heavy rain

This trail among all the beautiful others the watershed has to offer is one of my favorite local excursions for trail running and/or general nature meandering. There are almost never many people here, and the scenery is tranquil and stunning. The only thing is that I can’t bring my dog with me as the watershed doesn’t allow dogs. There are lots of friendly deer here. I love this trail

This is a pleasant walk in the woods. Gets a little muddy/slippery but it mostly well maintained. Watch out for bikes and horses. Lots of options to make this longer. Though I haven't used them, there are bathrooms at the parking lot.

Very nice afternoon walk. The only reason it doesn't get five stars is that it's truly just a walk in the woods. To get 5 stars from me, it's got to be somewhat strenuous and have rewarding views.

Great trail to do with young 9 & 13 yr old boys. Annoying horse poo everywhere but saw a huge owl and it was a very well paved/wide easy trail.
