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.

I rode the trail today near the nuclear power plant and it was poorly maintained. The gravel was very loose, a lot of fallen tree debris and quite muddy. I traveled on the trail north about 2.5 miles and gave up. I traveled back along US11 and then rode around the trails at the river flatlands which were a bit better. I guess I am spoiled with my local trails (York Heritage and NW Lancaster Co Rail Trail)

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!

Trail is nice however it's all broken up..they need to connect all this trail together to make it a nice trail

The flow of the trail is perfect as it follows the creek.

We loved this ride. We even had an encounter with a deer. It was lovely.

Lewisburg end start at the Miller Center/YMCA. First mile in Lewisburg is confusing and crossing Highway 15 is not at a crosswalk and the trail is not well marked. Mifflinburg end is just beyond the Rusty Rail restaurant. Lots of parking in that area. Lewisburg end first 2 miles are asphalt, many road crossings. Mifflinburg end is 1.5 miles asphalt. Middle is through cornfields and farm fields with several farm access road crossings. Could be a 5 star except for Lewisburg end and a couple of Highway crossings should be more visibly marked - cars don’t stop for bikes.

Started in Carbondale on the Lackawanna Trail and continued seamlessly to the D&H. Trail was nice compacted cinders as described up to Ararat trailhead, trail was nice continuous uphill climb at about 1-2% barely noticeable. Last mile or two to Ararat increased to maybe 3% and was noticeable. The scenery along this stretch was varied and beautiful with small lakes an Stillwater Lake which is dammed.

From Ararat to Starrucca Viaduct is also as advertised, minimum is Hybrid with suspension, the one review that said he did it without suspension must have reverberated for weeks. This stretch is downhill and would be very difficult riding the other way the downhill grade helped overcome the friction of the uncompacted gravel.

The big disappointment came as we neared the Viaduct, the trail markings almost diminished and alternate paths made it confusing we ended up riding into town and onto town roads to the Viaduct. The Viaduct should be a highlight for this trail and unless you start there which is not recommended you could struggle to find it.

The section north of the viaduct to NY was almost impossible to find and poorly maintained dirt trail, NY line wasn't even marked, total waste of time.
