If you like wide open and flat trails then this is for you. Was nice to bring my dog with me; Appalachian trail is too narrow and rocky for my dog on a leash. Overall it was pretty dry, very quiet, and walking next to the Paulinskill was relaxing.

Oct 11, 2021. Parked in Glen Onoko parking lot. Lots of parking, but we could not find any toilets anywhere. Seems like with all that parking for visitors, the town or park should at least provide some porta-potties. We rode north for about 15 miles. Almost all of the trail was in great condition. There were a few spots near Glen Onoko with very loose fill that required walking (32 mm wide tires). Very nice scenery, and not crowded on a holiday Monday. Nice facilities at the Rockport trailhead. Overall a great ride!

I did a portion of this trail, Whitehall trail head to East Church Street. It is mostly flat until you hit the loop section, that was a short hill, but a little steep. The only problem I had was crossing 2nd Street--extremely rough pavement, it's like they milled the road and never finished it! Except for that crossing the rest of the trail was fine. Plenty of parking at the trailhead, but there are more parking areas further up the trail as well. I didn't see any public restrooms, there are a few portable toilets along the trail. Plenty of benches and other seating areas along the trail, but no water fountains--make sure you bring enough water! There is a shooting range next to the trail that was Very active while I was skating, some people may be bothered by this, I wasn't. I went in the morning and there were other people on the trail but it was not crowded.

Run, walk, or ride! Great for everyone in the family!!

Have always loved the IRT - it is truly one of the best trails in the Lehigh Valley. I generally use the Chestnut Street or Saylor Park trailheads so I can choose if I want to do just the loop or the loop and spur section.

I was also pleasantly surprised that the ENTIRE trail is paved now! The last section of the spur route used to be crushed stone, but is now paved. This makes for an awesome ride.

Overall, it is a fairly flat loop with a spur should you choose to do it. On the loop, there is a hill that starts at the spur entrance and goes toward the Chestnut Street trailhead, then turns downhill to Saylor Park. On the spur route, there is a slight brief uphill as soon as you turn onto it, before you go under the Route 145 bridge. The scenery changes throughout the loop from dense woods to town parks to homes and apartments. The spur route is much more countryside, with the ruins of old industry and trains along the way.

The road crossings on the loop route are very manageable and since you are in towns most of the time, traffic moves slowly and/or is very good about yielding. This is a bit of a different story on the spur route, which has some busy road crossings, namely South Church Street (second crossing after bearing off on the spur) and Mauch Chunk Road (last crossing on the spur route). Mauch Chunk is especially dangerous with cars moving at a high rate of speed - there are signs on the trail warning that it is a dangerous intersection. However, all crossings are well-signed - it just seems to me that vehicle operators on the faster country roads along the spur route generally do not yield to you.

The only other compliant is toward the end of the spur route, the trail passes directly behind a very busy gun range. Although there are cement walls and fences dividing the trail from the range (and the range is pointed away from the trail), it can still be a bit unnerving to hear rounds being fired so close to the trail.

Overall if you pick one trail in the Lehigh Valley to try out, make it this one - you won't be disappointed!

This is likely a lesser used portion of the trail, and my review covers from the Fort Washington State Park trail heading northward. It is a trail that will appeal to mountain bikers and walkers. The starting point is not obvious from the parking lot, but can be deciphered relatively easily. The trail starts out packed gravel and flat and winds through some scenic areas. One then crosses a long bridge, and ahead is a fork, where one wants to take the right fork. There is a road crossing ahead, and it switches to macadam and remains relatively flat. One crosses under an old railroad bridge, and up a steep hill where the macadam ends. With heavy rains recently, there is a lot of erosion and the trail is very rocky. There are some steep stretches, and dips, and with the bicycle I had, I had to bail from the trail. I did see people further ahead on foot, and it appeared pleasant enough. It should be spectacular in fall colors. It is a relatively short trail, and families were walking along. I only give this portion three stars due to its difficulty unless one has a mountain bike and the need for repairs to the erosion. Although a recently fallen tree had been cleared, so there is some attention given to the trail.

I only did 40 miles of the trail staring in New Brunswick; did enjoy it. I was impressed by the difference in temperature provided by the tree canopy during a good portion of the trail. My only concern, especially when riding with children, is that little attention has been given to traffic intersections. Too many drivers are careless and could prove hazardous. An enjoyable trail otherwise.

I was really pumped to go for a long run on this trail, heard nothing but amazing things. But it seems TS Henry and Ida took its toll on this path. LOTS of washouts, bridges closed and areas completely washed away. I’m sure it will get fixed in time but just be cautious for the time being

We rode this portion of the D&R trail two years ago, and thought we'd do it again yesterday. Started at the trail head along Carnegie Road at Lawrenceville, and rode for about 2 1/2 miles going north-east (we were plaining on doing 20 out and 20 back) . That was enough to decide to pack it up, and go to another trail closer to home. I guess, because of the heavy rains we had in August/September, to repair wash-outs, they just threw very fine gravel down, not packed, and in many places about 2" thick. It made for miserable riding on our cyclocross bikes with 32mm tires. Whoever is in charge of the trail maintenance needs to educate themselves of proper materials and techniques to be used for the trail repairs. Maybe it got better as you got further away from Lawrenceville, but we weren't going to chance it. A real shame, it used to be a great trail.
