Moosehead Lake Snowmobile Trails Guide

Short answer: The Moosehead Lake region is in northern Maine, with Greenville at the southern end of the lake. Riders use Maine's Interconnected Trail System, called ITS, plus club trails. To ride in Maine you need a registered sled. Maine Inland Fisheries and Wildlife (IFW) handles registration. A nonresident season registration is listed at $119, plus an agent fee. Trails are groomed by local clubs, mostly on private land, so grooming depends on snow and on the landowner's permission. The lake itself is a separate matter. Treat ice as a hazard until you have checked it yourself.

No ice is ever 100% safe. Check it yourself.

Check a current trail report before you load the sled (see below). Reports are snapshots. Conditions change fast.

Quick facts

Registration and rules

Maine IFW runs snowmobile registration. Its page says nonresidents may register or renew online. Residents may renew online, but new resident registrations go through a registration agent such as a town office, or the IFW main office in Augusta. After an online transaction you get a confirmation page to print for immediate use. The official registration and stickers arrive by mail within thirty days. IFW lists the nonresident fees above. Resident fees are on the IFW page. Check it, because the fee table is easy to misread.

IFW also runs a Nonresident Free Snowmobile Weekend. The 2026 dates were March 6 to 8. During it, a nonresident with a valid registration from another state or province may ride in Maine. IFW had not posted 2027 dates when we checked. Look at the IFW page.

Other rules from IFW:

• A child under 10 may not operate a snowmobile unless accompanied by an adult. Exceptions apply on land owned by the parent or guardian.
• A person under 14 may not operate a snowmobile across a public way maintained for travel.
• Stay on marked snowmobile trails. ATV trails are not snowmobile trails.
• Drive to the right. Never drink and ride. Modified exhausts are illegal.
• Stop at every logging intersection, slow down at logging signs, and give logging traffic the right of way.

The trails around Moosehead

Two regional write-ups name the main routes. Both are tourism content, not official trail records, so treat them as a starting point and use the current ITS map.

• ITS 85. The Moosehead News guide says it connects Greenville to the northern and southern trailheads with lake views. A Maine Snowmobile Association page describes ITS 85 as a long north-south trail that runs as far as Fort Kent, so it is not a local trail only.
• ITS 86. The same guide describes it as a link between Rockwood and Kokadjo and the Katahdin region.
• Moose Loop Trail. Untamed Mainer says it circles Moosehead Lake and is Maine's longest snowmobile loop, 138 to 166 miles depending on route. It passes through Greenville, Rockwood, Seboomook, Northeast Carry and Kokadjo. Some parts are ITS trails. Others are local club trails. A cutoff runs through Rockwood past Mount Kineo for a shorter ride.
• Route 66 half-loop. Untamed Mainer puts it at about 55 miles, from Kokadjo to Rockwood to Greenville and back.

ITS 81: We could not confirm ITS 81 as a Moosehead trail. The one Maine Snowmobile Association page we found places ITS 81 near Limestone, far to the north. Check the current ITS map for your route and do not plan around an ITS 81 number without it.

The ITS map is made by the Maine Snowmobile Association (MSA) with the state snowmobile program. It is updated each year. The MSA says new maps are usually available by late October. Get this season's map. Trails and numbers change.

Grooming and clubs

Most Maine trails are on private land and are kept up by local clubs. The state says without private land most trails would not exist and your ability to ride is a privilege granted by the landowner. Respect closures. Stay on the trail.

A regional listing from The Maine Highlands names the Moosehead Riders Snowmobile Club in Greenville. Club trail reports and the MSA are the places to learn what is groomed. Hundreds of volunteers do the work, per the Moosehead News guide.

Crossing Moosehead Lake

Moosehead is a big lake. Regional guides say it can be ridden when ice allows and that it saves distance between shores. None of that makes it safe on any given day.

What we can source:

• A news report from a past winter quoted a local source saying clubs usually mark the trail across the lake. That year they did not, because ice thickness was inconsistent. The same source said riders who stayed on the marked trail were OK, but those who left it were pulled toward thin areas or open water, such as at the mouth of a river. Past conditions, not a forecast.
• The report also said the north end, toward Northeast Carry, freezes last and had thin ice and open places.

Thickness numbers: the Minnesota DNR publishes general guidelines for new, clear ice only. Stay off under 4 inches. 4 inches is for activity on foot. 5 to 7 inches is for a snowmobile or small ATV. For white ice, which is about half as strong, double those numbers. The same page says ice can be two feet thick in one place and one inch thick a few yards away. Temperature, wind, snow, currents, springs and narrow areas all change it. These are Minnesota guidelines used as a general reference, not a Maine rule and not a statement about Moosehead.

No ice is ever 100% safe. Check it yourself.

Safer habits:

• If the lake is not marked, take the shore trails.
• Never follow lights or tracks onto open ice. Tracks only show where someone went.
• Stay away from inlets, outlets, river mouths and narrows.
• Tell someone your route and return time.
• Carry a charged phone, a map, and a spare layer.

Where to check conditions

• Maine Snowmobile Association. Its site has a Trail Conditions section with club reports.
• Local clubs. They groom and know the lake.
• Weather. Check the National Weather Service forecast for Greenville.
• Maine IFW. For registration, rules and the free weekend.

Reports can be out of date by the time you ride. Treat them as a snapshot.

Do I need to register my snowmobile to ride at Moosehead Lake?

Yes. Maine IFW handles registration. A nonresident season registration is listed at $119 plus an agent fee. A 10-day registration is $99 and a 3-day is $74. The Nonresident Free Snowmobile Weekend is a separate exception for nonresidents with a valid registration from home.

Can you ride a snowmobile across Moosehead Lake?

Regional guides say yes when ice allows, but ice varies a great deal across the lake. Stay on any marked trail, and do not assume one will be marked. No ice is ever 100% safe. Check it yourself.

Who grooms the trails?

Local volunteer snowmobile clubs groom most of Maine's trails, largely on private land, with the state program and the MSA in support roles.

Where do I get the ITS map?

The MSA says the ITS map is updated each year and new maps are usually out by late October. Sources include the MSA office in Augusta, some chambers of commerce and local clubs.
