2nd visit to this trail in 2020. Trying to complete the whole thing. Parked in Summerville and biked to Brookville. Had lunch in Brookville. There are several places in town just off the trail. Biked back to Summerville and past it towards New Bethlehem. 35 miles on the trail this day.
Surface is packed crushed limestone but bumpy in some places.
Saw all kinds of cool history along the trail. This section crosses the Redbank Creek quite a few times via very nice wooden bridges. In Summerville there is a service station a few blocks from the trail if you need water and/or snacks.
Enjoying this trail very much and hope to visit again this Fall. Right now still very green.

Just got done running on trail for 1st time since back from out West. I moved out here in 2005 and started running the trail and in all those years I have never been able to run in July.... what the Shenango River Watchers have done with the trail is nothing short of amazing! Thank you!!

10/26/2020. Very scenic views and a nice ride with moderate obstacles.

We road from East Brady to Kittanning and back for a total of 44 miles. Riding that direction, you first go through about one mile of shared gravel road with private homes. The trail winds along the Allegheny River with beautiful scenery. It also follows a few camping areas. When in Kittanning a must stop to eat is at the Allegheny Mariner restaurant. West coast atmosphere, the best Mac and cheese ever (an we are M & C connoisseurs) and a skillet fresh-baked warm chocolate chip cookie with ice cream that is to die for! The rest of the food was homemade and excellent also. The Armstrong Trail is one of many great trails in PA!

What a beautiful ride! Gorgeous view of the river. Traveled 22.2 miles of quiet easy beauty! One small stretch of gravel was a drag by will be back! Traveled from Cleveland

We completed another 10 miles of this trail. Beautiful day! This time we started at the trailhead in Orwell. Love this trail. Very well maintained throughout. Mostly flat, however, this is one of those trails that you will pedal no matter which direction you head but nothing intense. Just a great ride.

We have done this trail many times over the years. We love that it is a challenging loop trail. Many rolling hills and a few steep ones too. Shady for the most part depending on the time of the year. Trail well maintained.

Trail could certainly use some help. Mostly grass with some sections where there is a little gravel. Very bumpy. We started at the Spillway which for the most part is dead center of the trail. Nothing is marked as to beginning or end; just kind of stops at both ends. If you're looking for short and flat, but rough, this is the trail for you.

Parked at the Redbank Valley and Sligo Spur intersection. I have rode the Redbank many times and decided to ride the Sligo today. From mile 0 to 4.8 is all up hill. Supposedly less than a 4% grade. The next 2 miles are down hill, next 1.6 uphill, and the last .6 downhill. The trail will just end at a dirt road. The trail is mostly through woods and cinder trail that is in very good shape. You will also see three beaver dams(mile 1.0, 1.2, and 6.8). You will also crossover three streams that are orange from mine run off. This is not a trail for beginners. The uphill is some work. Most of the downhill part you will coast. RPD1 Sept 21, 2020
