Wadhams to Avoca Trail – Michigan Bicycle Trails

The Wadhams to Avoca Trail is located in the southeastern part of Michigan’s Lower Peninsula. The south end of the trail is actually just about 2 miles west from downtown Port Huron.

The Trail

Like many other trails in Michigan, it is a rail-trail. It was built  in the early 2000s on a former railway line.

The trail is 12.5 miles long. First 5 miles from the south, the section from Griswold Rd to McLain Rd is paved. The rest is a two-track, either dirt of thin layer of finely screened limestone. Both sections are quite smooth. On the unpaved section you might run into an occasional chipmunk hole.

The trail is pretty much completely flat, and if there is any incline or decline, it is so slight that you will not be able to see it. (My GPS recorded less than 200 ft of elevation change during the round trip of the entire trail.)

The trail is not heavily used. I rode it on Sunday, and while I encountered people on the entire length of the trail, the numbers were quite small. I probably never had more than 2 – 3 people as far as I could see in front or behind me. So, I can only imagine that during a week, especially during the day, you might be there alone.

The northern, the unpaved section, is frequently used by horseback riders. So, don’t be surprised if you run into few people riding horses. They have the right-of-way, so let them pass, or pass them carefully, as horses get spooked easily. The best way is to ask if it is OK to pass. The riders usually know how the horses will behave…

The trails passes by some residential areas, industrial sights, farmland (mostly north section), but mostly it is surrounded by trees and bushes providing it with some good amount of shade.

The Mill Creek Trestle/High Bridge

The main attraction of the trail is the Mill Creek Trestle called often a “High Bridge”. It is located about 1.5 miles south of Avoca. The steel trestle is 640 feet long and 60 feet high.

Often, when you see articles in press or online about the trail, it will show the impressive picture of the bridge. Unfortunately, from the trail you cannot enjoy the view of the mighty structure. You get the nice view of the narrow and lazy Mill Creek below instead.

The southern most parking lot by the trail is in town of Wadhams, west of the Wadhams Rd.

There are two gas stations with small convenience stores and Wendy’s right by the trail.

Avoca is one of those one street towns. But right by the trail you have a market and also a diner.

The northern parking lot is right at the trail end on the southern side of Avoca Rd and east of Kilgore Rd.

The last one is at Wadhams Rd. This one does not have any restrooms. (42.9823624,-82.5383729)

There is no parking lot at the south end of the trail at Griswold Rd. I’ve seen there cars parked on the shoulder. However, I would not recommend it.

Camping Options

For those who are touring the places where they can stay overnight matter. The Wadhams-to-Avoca Trail offers few camping options.

Maps, and Google show another campground by the trail – Fort Trodd. However, it’s not good for bike tourers. It is a RV, seasonal campground.

Final Thoughts

The Wadhams-to-Avoca Trail is a great route to go for a leisurely bike ride.

However, since it is not connected to any other trails is only offers the maximum riding distance of 25 miles, which is kind of short for any serious cyclist. This is the biggest limitation for people that would come from a distance away. Since many riders have the rule that their round trip drive time to the trail has to be shorter than their ride time.

So, it is pretty much a nice choice for riders from Port Huron area.

The local government is trying to advertise it with images of the Mill Creek Trestle. However, as I mentioned before, you cannot admire the view of the trestle from the trail.

However, if you are looking for some different smooth, easy to follow, trail to ride, where you won’t run into tons of people, the Wadhams-to-Avoca Trail will be a nice choice.

Helmeted Guinea Hens
If you are lucky, you might run into Helmeted Guinea Hens on the trail, which must be raised by somebody nearby, as they are not native to the U.S.
