Before You Ride the TWAT: What Street Legal Riders Actually Need to Know
TL;DR: Most of the TWAT runs on public roads and two-track where your regular DMV registration is all you need. But specific sections — the Perkinstown trail system and sections north of Highway 8 — run on designated state ATV/OHM trails that require a Wisconsin DNR Off-Highway Motorcycle registration. It’s a small fee, takes minutes to get online, and if you’re doing the full route, just get it. Don’t find out at the trailhead.
What the TWAT Actually Is
The Trans-Wisconsin Adventure Trail is a 635-mile route that runs the full length of Wisconsin — from the Illinois border near Hazel Green in the south to the shore of Lake Superior in the north. It was designed to avoid pavement wherever possible, stringing together back roads, forest roads, logging two-track, and designated OHV trails into one continuous north-south line through the state.
It’s not a loop. It’s a line. And if you finish it, you’ve crossed the whole state the hard way.
The terrain changes dramatically depending on where you are on the route. The southern Driftless Area is all ridgelines and river valleys — technical in spots but manageable. Central Wisconsin opens up into farm country with fast dirt roads. Then you hit the Chequamegon-Nicolet National Forest and things get serious — rocky climbs, sand sections in the logged-out areas, and some of the best riding in the Midwest if you’re on the right bike for it.
No official map exists. The community-maintained GPX track at transwisconsintrail.com is what most people run.
Running the Official GPX? You Need the OHM Sticker.
Here’s the practical summary most riders miss: the community-maintained GPX file at transwisconsintrail.com routes you through both designated ATV/OHM trail corridors and forest roads. It doesn’t separate them. If you load that file and ride the official route, you will hit sections that require a Wisconsin DNR Off-Highway Motorcycle registration — specifically the Perkinstown system and trail corridors north of Highway 8.
The bottom line: if you’re running the official TWAT GPX, just get the OHM sticker. It covers you for the whole route, it takes minutes online at gowild.wi.gov, and not having it on the sections that require it puts you in violation. Don’t piece-meal it — get it before you leave.
Street Legal vs. OHM — What the Difference Actually Means on This Route
Here’s where it gets specific, and where a lot of people show up confused.
A street legal motorcycle — anything registered with your state DMV, plated, insured — can ride the vast majority of the TWAT legally. Most of the route uses roads and trails where standard vehicle registration is all that’s required. If your bike has a plate on it, you’re good for most of the miles.
Wisconsin’s DNR Off-Highway Motorcycle (OHM) registration is a separate thing. It’s specifically for riding on Wisconsin’s designated ATV/OHM trail system — the trails the DNR maintains, funds through sticker fees, and closes to non-registered vehicles. An OHM, by Wisconsin’s definition, is a two-wheeled motor vehicle designed for off-highway use. Your plated adventure bike doesn’t automatically qualify as a registered OHM just because it can handle the terrain.
The practical takeaway: when the TWAT route dips onto a designated state ATV/OHM trail corridor, you need that DNR sticker to be there legally. When it’s running on forest roads or county two-track, you don’t.
The Sections That Require the DNR Sticker
Two areas come up consistently:
The Perkinstown Trail System — This is a DNR-managed ATV/OHM trail system in Taylor County in central Wisconsin. The TWAT routes through it, and it’s one of the more popular sections of the trail because the riding is legitimately fun — tight, wooded, well-maintained. But it’s a designated trail system, which means DNR registration required.
Sections north of Highway 8 — The northern half of the route has more overlap with designated trail corridors. Once you’re above Highway 8 heading toward the Chequamegon and Lake Superior, you’re in territory where the trail mixes with ATV/OHM trail systems more frequently. Know which sections you’re on.
If you’re planning a full north-south run, you’re going to hit both. Just get the sticker before you go.
How to Get the Sticker (And Why It’s Worth It Even If You Could Skip Parts)
Wisconsin DNR OHM registration is handled through the Go Wild system at gowild.wi.gov or in-person at a DNR-authorized license agent. Check current pricing at dnr.wisconsin.gov/permits/registrations/OHM — fees can change year to year.
Non-residents who don’t want a full OHM registration can also look at a non-resident trail pass for shorter visits.
The inconvenient truth is that Wisconsin doesn’t make this easy. Unlike some states where you can grab a pass at a gas station on the way to the trail, the WI DNR OHM system requires a little more legwork. Do it before you leave home.
As for whether it’s “worth it” — the sticker fees go directly to trail maintenance and documented rider presence on the state ATV system. Every registered user strengthens the case for keeping those trails open and funded. The overlanding community has watched enough trails close to know that showing up on paper matters. If you’re going to ride it, register for it.
Perkinstown Is Worth Your Time
The Perkinstown section deserves more than a regulatory footnote. It’s one of those trail systems that changes the trip from a point-to-point route into something you actually remember.
The trails wind through Taylor County forest — mixed hardwood, occasional meadow openings, well-maintained corridor. It’s not gnarly in the way some of the northern forest sections are, but it’s fun and it flows. Good beginner to intermediate terrain for most dual-sport bikes.
And when you’re done, Outboards Tavern is right there. Local bar, sandwiches, exactly what you want after a morning on the trail. Small Wisconsin town, the kind of place you’d ride past without thinking twice if you didn’t know about it. Now you do.
Before You Leave: Quick Planning Notes
The TWAT is not a supported route. There’s no trail crew, no official signage for the route, and cell coverage in the northern half is inconsistent. A few things that matter:
Download the GPX before you go. transwisconsintrail.com has the track file. Load it into your GPS unit or REVER before you leave — don’t count on data in the Chequamegon.
Get your DNR OHM sticker in advance. You can’t always get it locally. Handle it online before the trip.
Know your fuel range. Small towns, inconsistent gas station hours. Plan fuel stops before the remote sections, not during.
Check seasonal conditions. Spring mud and fall hunting seasons both affect access and what the trail looks like. Some sections are better avoided during wet conditions.
Carry paper backup. A screenshot of the route on your phone counts. Something that works without a signal matters up north.
The TWAT is one of the better-kept secrets in Midwest adventure riding. 635 miles of the state on a line, most of it off pavement, two meaningful sections that need a sticker to ride legally. Now you know.
