The part in Durham I got to ride was shady and well-maintained but I'd never ride it again. I'm used to riding trails that have long stretches and don't cross dangerous, busy streets every block or so. While this trail would be *excellent* for walking and I do see people biking, it's not one I'd recommend for the latter. There are too many opportunities for a bad interaction with an inattentive driver. I had a near-miss with a driver who didn't respect the trail/crosswalk warning lights as it was.

A wonderful break from driving i95, thank you traillink, parking was easy and free. There are rolling hills and friendly walkers.

Let's start with this.
The trail is not flat.
Level, yes. Paved, yes. Mile markers every half mile. Mostly shaded (good on a very hot day) Flat, no.
There are a couple pretty decent hills, saw a biker walking her bike up one.
If you start at Jordan soccer park, it is mostly down hill, which means back up.
A couple little bridges, one good size covered bridge over the creeks make for nice scenary, along with the skinny squirrels.
Another runner said the further end was more flat. Next visit I'll plan to run entire trail.
So, as usual. If in the area and want to get a few miles in, head here. You will enjoy the trail and the challenge.

This greenway is poorly marked and the trail is broken in places by a detour through busy city streets and 50 mph traffic. This was an awful ride spent being slightly lost and pretty frustrated at the large detour required to get back on the greenway trail. I won’t be back.

I'm fortunate to live within walking distance of the ATT. I walk or bike on it almost every day. Most of my mileage is on the southern half of the trail, south of Southpoint shopping mall. With that in mind here are my observations:

It doesn't have much dramatic scenery, but it does have and promote a sense of serenity along most of its length, which is all the more amazing when you consider that it cuts right through the busy RTP metropolitan area.

The trail is ALWAYS well maintained.

At the southern terminus of the trail, you can see that the rail bed continues, but is blocked by a barricade. Looking at the satellite photos of this area My fervent hope is that one day the rail-trail will be extended down this corridor.

As you would expect in an urban area, the trail can get overcrowded--especially on weekends.

I used to live right on the ATT and absolutely loved it. The trail is nicely kept and is shaded through many parts of it. The ATT made my runs so easy and it is easily one of my favorite trails that I have ever ran.

Great trail for a morning walk. It's part of the Cary Greenway and connects to other trails

I had an extra day to spend in the Triangle before heading home, and was excited to squeeze in a ride on this trail. I parked at the White Oak trailhead, which has restrooms. The stone trail was among the best I’ve ever seen; extremely wide, smooth, well-packed. Lots of tree cover, gentle hills. They use the old-fashioned access control gates on this trail, which are a bit narrow to ride through even at a slow speed. But road crossings were not too frequent and didn’t slow me down.
Even though it was a Saturday and a lot of people were using the trail, I didn’t feel hampered to ride at a (relatively) fast pace. The mix of families with strollers, walkers, runners, and riders all got along quite well. I rode to the end of the stone section, then back past my car to the paved section and into Durham. There was a bigger hill and one very urban area where the trail narrows and becomes effectively a sidewalk, then opens up a bit and dives back into the trees. I continued to Mile 5 and turned around where it seemed to be getting more urban again.
And despite the trail’s name, not a single smoker in sight the whole way.

I have wobbly ankles so some of the trail was moderately challenging (as opposed to running on flat asphalt) but it is truly gorgeous scenery and a lovely run. The restrooms were clean, the views were gorgeous and I look forward to running here frequently and bringing my kids to kayak. I'd easily rate it 5 stars, however I tripped on a root and gouged my knee pretty badly. If I wasn't so clumsy this would definitely rate 5 out of 5 stars.
