Tunnel is closed. I ventured over the top and it's tough
Very nice scenic trail. Many places to stop along the trail to stop and take in the scenery.
Please make sure you have bike lights, flashlights etc… those tunnels are dark!!
I just rode the trail 11 Oct 2025- shortly after the new Sideling Hill Trailhead grand opening a couple of weeks ago. I utilized the PA Turnpike to drive up from Harrisburg area- very easy and trouble free- just know that afterward you have to drive another 10 miles UP the turnpike to turn around and head back to Harrisburg....ugh 20 additional miles, even though both East and West bound have access to the Sideling Hill Rest Stop. Trail Head had really nice bike servicing equipment and picnic tables- Lots of food options at Rest stop- everything you need after 20 mile ride- Burgers and Pizza!! Leaving the rest stop- you ride a service road that is open to bikers (Mountain House Road). You then come to a 4 way stop- Make a left on North Hess Road- you will see a old farm/log cabin house on your right (see my pictures)- go straight this road will turn in to Pump Station Road- ride for about 1/4 of a mile do not turn on the first unmarked road on your right- go to the second road on your right just after the first one- look for a mail box- there is a home that shares the access- ride past home and you will be at the TOPP Trail- you will see cement road barriers on your left- this is the entrance to the trail- Enjoy your ride for the next 8 miles or so. The first tunnel you reach is about 1.5 miles up- This one is long and dark maybe a mile long. The second one is shorter. The trail is rough in sections due to the blacktop being torn up- if your a Pennsylvanian- this a typical PA road LOL potholes! Beware if you are with children or offend easily- There is a TON of Graffiti and things that will make a sailor blush (I used to be in the Navy). There is some really talented art work along the ride though. I would recommend mountain bikes or gravel bikes- my bike has 45MM tires and I rode with 35 psi which I thought was perfect for the rough areas. This trail was "Creepy Cool" and a perfect ride for a fall day and Halloween around the corner!
Friendly folks walking the trail. Nice they had a few porta johns along the way.
We rode the trail end of September 2025. Gorgeous day cool temps & sunny. Later in the day it got warmer but this trail has plenty of shade. Fallen leaves all over the trail made it so beautiful. Since we don’t have a fall season in Fla. we were embracing the beauty in front of us. We rode 8.5 miles one way. It’s a must do when you’re in the area.
We just finished the GAP trail & C&O towpath 9/20 from Pittsburgh to DC. We took 8 days and our days ranged between 32 miles to 63 miles. Highly recommend this trail. Well maintained, accessible and clean port a John’s, always had plenty of toilet paper and were frequent enough to remove any anxiety about not being able to relieve yourself in privacy. Potable water was available along the trail which we still used a filter just to be safe. Beautiful trail, friendly riders and towns to visit. We rented a full sized SUV in DC and dropped it off at the Budget on Stanwix St just two blocks from fountain starting point. Worked perfectly to get going on our ride without delay.
Perfect day for a ride and on the first day of Fall. Trail and views were breathtaking!
I just completed the entire GAP. It was well worth it. The trail was in good shape and there was not too much traffic. I’d like to do it again.
Did this trail this afternoon. Ride on the roads for short distances. Signs point where to go. Rode around IUP campus for awhile. Would do again if it was not so far from home (1hr or so)
We live near this trail & ride it often (as well as the GAP). We decided to use the spur at Werhum & see how the new bridge is coming along to complete the "loop" everyone is waiting for. We discovered new signage (THANK YOU RTT!) and found a new spur through the woods to a small lake / large pond that we never knew as there. Awesome state park attached. Then met a guy on the trail who informed us that Nov. 2025 the loop should be done for GTT. This trail is fantastic. A golden nugget for a big ride day. We did 39 miles and didnt complete it all. Coming down hill from Nanty Glo is always a treat, but there has been some trail dammage and is well marked for that. They have improved it alot from early spring rides!! But still be aware its there. Enjoy!
