Beautiful. Beautiful. Beautiful. During our trip the trees provided a wonderful canopy from the rain and the hot summer sun for most of it. Great trail with some exciting challenges throughout.

Just hiked this today with my dog (4 month old lab). He loved it just as much as I did. Definitely recommend this trail for someone who’s looking for a beautiful hike with a slight challenge to it. One of the best in the area in my opinion!

Great hike, lots of rocks and tree roots to keep you in your toes. A stop in the Grist mill is definitely a plus. I’m just sad that I didn’t do this hike sooner. I will definitely do it again.

Did the trail this morning with 4 kids 5 and under. All were able to make the whole trail walking on their own. It was definitely tricky in spots, and you have to be careful on the narrow spots. But it was absolutely beautiful. Multiple waterfalls along the way, interesting wildlife, and gorgeous scenery along the river the whole way. Definitely worth it!

Gorgeous scenery, hike loop is short but a good workout, easy to access, close to cities.
PLEASE NOTE - very dangerous, slippery rocks (hence the creek name) next to whitewater current creek. Respect the dangers and stay on the trail.

Great hike, like lots of others said, just watch your footing. My (newly) 4 year old hiked the whole trail, with me holding her hand for most of the uneven terrain but enough space for me to walk with her. My husband had our 2 year old in a backpack carrier. She did the flatter areas at the beginning and end by both bridges. Kids loved the little waterfalls and saw a newt.

Had a great hike on this trail, even stretched over to backend of Slippery Rock Gorge trail, another fun hike. This one has a nice trade off; while there are few uphill “pushes” one must be aware as it consistent in its embedded rocks and endless winding tree roots. Stay aware! But get yourself on this trail soon.

Had so much fun with my 4 boys on this trail! We spent some extra time crawling around on the rocks, playing on the beach, and watching kayakers.

Great hike, rocky so you definitely need to watch your footing. But beautiful views the whole way.

This was a great hike. Lots of rocky terrain, my Girl and I took our dog and had a blast.. backside of the loop has a lot more rocky terrain and climbing. Great photo spots along the way.

Absolutely beautiful hike with loads of scenic spots. the one side of the trail may be harder especially for kids, but is easily passable.

Great loop walking along the creek the entirety of the hike. Easy-moderate. Not much elevation change except at beginning/end, but there are a few squirrelly spots with slippery rock in narrow passages (pun intended). Definitely muddy and some points where our boots got wet from shallow running water down the hill.

It’s a nice little hike. Even with several inches of snow on the ground. It’s absolutely beautiful!

This was out first time on this trail and we were pleasantly surprised. The views are beautiful and the trail intices you to get close to the waters edge. I am looking forward to coming back when the sun is HOT, but even with the cool temps I worked up a sweat.

An unexpected thunderstorm (accompanied by hail, no less) made for a hastened trot on the wet rocks of Kildoo.

Nice trail, could be very slippery when wet. There are a lot of rocks and roots on the trail. The scenery was great.

The trail is in pretty good shape this year and mostly white blazed. They had a few sections where blue plastic was tied around the tree that wasn't blazed yet. It's a great up and down trail that's easy enough to follow and not get lost.

Kildoo Trail begins at the covered bridge, and the first 1/4 mile to the waterfall is easy and kid-friendly. Just beyond the footbridge over the falls the trail becomes rocky and more difficult. Crossing the Eckert Bridge, about 1 mile downstream, and joining the blue blazed NCT to return upstream to the covered bridge makes this a loop. The Slippery Rock Creek has dangerous currents and no swimming is allowed anywhere in the park. Stay on the trails for safety, and for the sake of the fragile and beautiful ferns, trees, and flowers.
