I took the part of this trail formerly known as the I-670 trail, from Cleveland Ave. until it meets up with the album creek trail. The path was in poor condition, with many bumps and cracks as well as a large amount of glass I had to avoid. I would not recommend using this trail.

FWIW I use this trail a lot and enjoy it. However, certain parts are in need a a repaving as it’s either dirty or cracked (and soon after a rainstorm parts remain flooded for up to a day). Additionally, it’s crowded but not enough to hinder my ride normally.

Alright, let's get the lion out of the room - this isn't a continuous trail that you can ride for hours like the Olentangy, Alum Creek, or Scioto. That's probably why it has far fewer reviews, and generally less traffic.

But if you instead look at it from the possibility of an after work ride, perhaps with dinner in Creekside Gahanna, which connects up with it very well, then it's quite nice. The sections by the river are just as scenic as the Alum Creek Trail, and the bluebells in the forest are in full bloom this time of year.

The Gahanna section is also de facto connected, contrary to what TrailLink shows. The Central Ohio Greenways map at http://centralohiogreenways.com/interactive-map/ is more up-to-date, and shows that the only on-residential-road segment is on Nob Hill Drive. There's also one very short sidewalk-or-street section on Cherry Bottom Road just north of Johnstown Road; the full-width trail resumes north of Springbook Drive, one street later. But aside from that, you can get from Morse Road to I-270 by the airport on trail the whole way.

Signage could be better; it's very good for telling you which parks different cutoffs lead to, but not so good for telling you which way to go if you want to follow the main Big Walnut Trail. Gahanna could study what Columbus has done on the Alum Creek and Olentangy Trails for the next level of signage improvements; in the meantime have your preferred map available on your phone.

Longer term, it would be nice if more of this trail were connected; Big Walnut Creek appears to have the potential to support a trail rivaling its more well-known cousins. But until then, consider checking out the Gahanna section for a nice relaxed evening ride.

I rode this trail on 4/21/2022, my second ride on it but first since 2014 or 2015. The City has made some improvements to it over the years, with one of the most obvious ones being the 2021 repaving of the eastern section along I-670 that connects up with the Alum Creek Trail. I remember that section being a bit of a boneshaker on my previous ride, but it's smooth as can be now, a very high-quality surface.

Once you are past the repaved section, the trail looks kind of like a sidepath, being concrete, but is plenty wide enough, and you have dedicated trail all the way until you are west of Cleveland Avenue. It's only once you get west of 3rd that the traffic noticeably picks up, but the routing along Nationwide Avenue is sensible - that's a high-pedestrian-crossing, low-vehicle-speed road, so it's pretty decent for sharing a lane (but stop at the stop signs and don't run anyone over on your bike!). Neil Ave is a little faster (35 mph?), but it's short before you reach North Bank Park.

Another option is to continue west on Nationwide Avenue, past Huntington Park and to New Crew Stadium. From there, you can cross the new-in-2021 pedestrian/cyclist bridge to the Olentangy Trail. It's worth seeing the new stadium if you haven't yet, shouldn't be busy if it isn't a Clippers/Crew game day, and saves you some distance if you want to go north towards Grandview or OSU anyway.

Scenery-wise, I-670 isn't at the top of the list, but it is kind of cool seeing the Downtown Columbus skyline gradually come into closer review, right up until you're at High and Nationwide looking up at a 38-story skyscraper. Fort Hayes (east of Cleveland Avenue, between all the freeways) is also a highlight, with plenty of green space, woodchucks, and great architecture on the buildings; it's worth a short diversion from the trail.

I rode this route on 4/23, for the second time overall but first this year. It's a beautiful trail. Shade most of the way, so a good option in the summer. As you get towards Newark, it parallels Raccoon Creek. The trail is in good condition, and Wildwood Park on the west side of Granville (10 miles from Johnstown) makes for a great place to stop for a break on the way.

I'd put this trail up along the top Central Ohio trails for scenery and relaxing rides, alongside the Kekosing Gap and Alum Creek trails.

Johnstown is at a higher elevation than Newark, so if you want the second half to be downhill, start at Newark. It's only about 300 feet difference, but the steepest part is by Johnstown, so if you start there you'll hit the elevation right when you're most tired.

There's a connector at 40.04666448775512, -82.47659987791373 that lets you get close to downtown Newark, or to OSU Newark (the "Newark Trail" on TrailLink); or take an alternate route back via Newark-Granville Road in Granville (not on TrailLink, but a dedicated bike path most of the way). This would be a good area to add a sign with directions.

There's also a short connector to Raccoon Valley Park near Granville, which isn't on the map but would be another valid area to park and start if you aren't from one of the communities along the route.

I re-rode the Camp Chase Trail from its eastern terminus to Battelle Darby Creek Metro Park today, and rode the section from there west last year. It's a nice trail, in good condition, and the gaps have been filled in over the years. Of particular note is that the gap orangedoug mentioned, at the Metro Park, was closed in March of 2020. It is a bit difficult to find the connection through the park from the west though; go to the roundabout at the west end of the parking lot, and find the trail branching off southwest (which would likely be the last direction you would expect to find it), and that's the connector, with an Ohio to Erie trail marker hiding in the woods.

I rated the trail 4/5 instead of 5/5 because while it is in good condition, it's the least scenic of the "big 5" trails in Columbus. I ride the Alum Creek Trail and Olentangy Trail every year; they're beautiful. Comparing this trail to the Alum Creek, the major difference is you forget you are in a city on the Alum Creek Trail. On the Camp Chase, for the first 7 miles going west, it's almost all city (there is a park area near Wilson Road). It does open up and become more scenic past Georgesville Road. Realistically, the section east of there is a "every few years" trail for me.

Parts of the eastern section were also reminders of the increasing poverty in parts of west Columbus since the pandemic; tent encampments were set up along parts of the trail and the parallel railroad, which hadn't been present the last time I rode the trail in 2020. In the afternoon of one of the first warm days of the spring, it didn't feel dangerous, but if you're planning an Ohio to Erie trip and aren't from the area, plan to be Downtown before sunset. At least the trail seems to be of use to the residents living by it; several tents had bikes by them and one man was working on his bike from the tracks when I went by in both directions.

The Hilltop Connector to the Scioto Trail at the eastern end is not a bad connector at all. Road speeds are moderate, most of it has a dedicated bike lane, and even at rush hour it didn't feel risky (and I'm not someone who rides roads).

This is 5.4 miles from Newell Park on County Line to Hartford Rd just east of Sunbury. You can get thru Sunbury and pickup Sandel Trail. Now, if they go north from Newell Park about a mile it will connect to Heart of Ohio.

I rode the Sawmill Parkway Trail on 3/20/2022, starting just north of US-750, and going to the northern terminus, and exploring some of the connecting trails in Powell on the return. Slightly longer than TrailLink reports; my odometer (which tends to slightly underestimate) reported 8.7 miles one way, and I started just north of the official southern endpoint.

The trail's condition is generally very good, although a small section near Olentangy Liberty High School is worn. It should be suitable for all bikes.

The southern half (4.5 miles) is along a relatively highly trafficked part of Sawmill Parkway, with just a strip of grass between the trail and the road. You aren't close enough for it to feel risky, but you're constantly aware of the traffic, and it just isn't very fun to ride. It's kind of like the section of the Olentangy Trail that parallels 315 in that regard, but four times as long. Some shrubberies or other small plants would improve that part of the trail.

The northern half is much more scenic, in part because there is much less traffic once you get past the last subdivisions. It's a calm, relaxing ride, and as you approach the northern end you'll likely see some Cessnas, maybe a Learjet, flying overhead. Once you get to US-42, cross both zebra crossings and continue along the path, taking a right at the dead end. You'll be able to watch planes taking off and landing at Delaware Airport. Definitely a cool experience that most trails don't offer.

Once you return to Powell, you'll find a surprising amount of connecting trails; Powell has done a good job with building trails, and if they aren't at the level of Westerville or Dublin yet, they're at least well on their way. It should be fairly easy to find a place to eat, or you can just explore at random. Only downside is bike parking hasn't always caught up with the trail.

Which leads to the other point - other than the parks that connect within Powell, there isn't much supporting infrastructure north of route 750. A few small parking areas (and I did see a few people out walking who had parked there), but no water, restrooms, or signs. At 17 miles round trip, it might be nice to have some amenities partway through - or if there are some via a branch, then signs to them.

Recommended if you're local, or if you've already done the Olentangy/Alum Creek/Scioto/Genoa Township trails and want to ride somewhere new.

Beautiful!!
