Pleasant hike through hilly forest terrain. Follow the blue trail from the trailhead at the NE corner of the lot. Stay with the blue trail to the millpond. At the end of the millpond, turn left on the millpond dam. Turn left on the path and make an immediate left to climb through the open field. Follow the farm path through the farmstead. Turn right out of the farm yard. After a short walk, watch for the unmarked trail going left from the path. It will lead you straight to the yellow trail. Follow the left (straight) direction of the yellow tail. The trail goes through pretty forested hills and valleys, with a couple of bridges, on its way to the Arc Monument, where the Delaware Arc meets the Pennsylvania Mason Dixon line border. Continue on the yellow trail back to the Trailhead in the parking lot. IGNORE the XC markers, their colors are for the high school cross country turns.

The trail markers do get confusing at certain points. I tried to follow the trail but ended up meandering through other pathways eventually. The trail is also mostly packed grass which is something to be aware of. Don't bike this trail after it rains. The trails and grass are wet and your bike won't have any traction. I almost wiped out going down one of the hills. There is some difficulty with the hills on this trail. However, some parts of the trail are flat. There are also some good views to be had but parts of this trail are certainly overgrown.

Beautiful trail! Good place to bring your dog so long as you’ve got a leash.

Parked on Arc Rd. and followed to Arc monument to pick up the trail. It was very easily marked and well kept.

Nice little walk, big hills at the end. A very tiny part of the trail in the middle is closed for maintenance.

Good trail, but the markings can be confusing and misdirecting at points. The app helps.

Okay trail, grades are bad allowing ditches to form on most of the trail

Well maintained trail and quiet once you get back into the woods.

Nice meandering trail mostly through the forest. I hiked counterclockwise and entered from the northernmost connector trail from Creek Road/PennDel Trail. The climb to Twin Valley Trail from there was a tad challenging for my 61 year old body. Once on the Twin Valley trail the elevation changes were easy. The "shared use" trail connects Tri Valley Trail to Creek Road/PennDel Trail is closed and completely overgrown so if you do enter from Creek Road exit at one of the two purple blazed connector trails to the north of there.

Interesting trail. Bridge out but we went around it. It was good to have the app cause we ended up off the trail twice. Overall a nice trail, just pay close attention to the signage.

Beautiful trail with mostly shade but it is currently overgrown in a lot of areas and a small portion is closed for maintenance. Some trails could be better marked but that also goes with the trails being overgrown.

As a beginner hiker the trail was challenging but not overwhelming. Certain sections presented beautiful views.

As of 3/7 there is a lot of maintenance going on in the park. Several places on the trail were closed and I used the trail map to find alternate routes around. I would love to come back in better conditions, but for now, I wouldn’t recommend this hike unless you live close by. There is a fair amount of noise from passing cars and heavy equipment (eg chain saws) associated with trail maintenance and nearby properties. This area is more of a lightly wooded park than a forest trail. Great for trail running, especially once they finish the maintenance. Note: my phone went dead during the recording, so take that into account if you review it for time and distance.

More than moderate, got off trail a few times but was able to find my way with GPS.

Very nice! Did the twin creek trail it was long

This is known as the Twin Valley Trail locally and by the Park. Very nice trail with modest elevation changes, a couple of creek crossings, and some nice views. Great family hike. My wife and I have done it with a two and a half year old and one year old strapped to our backs. Our now four year old had walked most of it on her own two feet. Most of it is under tree cover so a good hot weather hike. Plus, you get the Arc monument, so an interesting bit of history/geography thrown in.

Took my kids lots of cool things to see during the hike from nature to ruins of old houses.

I grew up in Newark but never ran any of these trails. Wow! So much fun. Well-marked and maintained. Beautiful and green. Loved it!

This is White Clay Trail! Not the arc monument. They charge you $4 to get in the state park to access the trail
