This trail is well kept but very, very rocky and steep in some places. It’s listed as “moderate” but I assume that is for the experienced hiker! It was a challenge getting up, and even harder going down because we were so tired! My son had no problem but he’s 11 years old! Make sure you have plenty of water and snacks to rejuvenate!

Dog friendly, but very rocky. Moderately challenging.

This was my first hike. I consider myself in shape, work out with weights, run...but this should definitely be labeled as strenuous. It's all up hill going to the summit and very, very rocky. I met an experienced hiker who agreed that it should be labeled strenuous. I really loved the scenery and it was an amazing hike. Would totally do it again... but might not go to a party the night before

Great trail up to fantastic views on Black Rock Cliffs. Good shoes recommended for the very rocky start to the trail. Agree with other commenters that it’s worth the 20 minute walk to Annapolis Rocks.

Great trail. Did see two copperhead snakes during the hike. One on Thurston just off the side and one at Pogo campground.

Great trail- shaded and beautiful with ferns and mountain laurel. After Black Rock- continue on- it’s basically a flat walk to Annapolis Rock- but as you walk on the mountain laurel in bloom is stunning!!

Very nice overlook at the end. Lots of shade on the trail. Cross a couple streams, definitely need solid boots or waterproof shoes! Definitely a trek when going up, but a breeze going down!

The overlook at the top is beautiful! The trail itself is a little overgrown and VERY muddy and rocky. Otherwise, I didn’t find it too tricky. Good shoes would definitely be helpful. It’s only an additional mile to Annapolis rock and I definitely recommend it. The parking lot is small so getting here early would help.

Several “water crossings. “. Muddy at portions. It was shaded most of the way. I wouldn’t say it has a waterfall

It's a nice hike. I love the stretches of shade and frequent access to cold water to sit next to for a break. Last time I saw a baby deer, which was really neat. I also saw what I think was a rattlesnake, so definitely watch out!

Hubby and I hiked this one - we really enjoyed it, but it is a bit rocky. Loved the streams and you could hear the water throughout, which was peaceful. The view at Black Rock made it worth the hike!! Breath taking views!! Will definitely be back.

A little muddy in places due to rain and there being several streams. A nice little hike overall. The view was great. I highly recommend this hike over nearby Annapolis Rock. It’s much less trafficked. There were people, but not too many that we couldn’t keep a safe distance or enjoy ourselves. We tried Annapolis Rock first and the parking lot was nuts. Either go there early, or take this trail and then cut over to Annapolis rock near the top. Whatever you do, don’t try to park at the AT off of 40 beyond early morning.
