Limited trails, but if you rally wanted to use an ATV, you will find 300 of your best buds from Anchorage and Fairbanks already there and farther than you will be able to go to get away from the crowds. Not worth it to take at all or go on that adventure. Unless you like hunting with crowds... A couple places up the Parks hwy that have old trails, pretty abused by swamp buggies and tracked, making ATVs pretty ineffective. The 40 mile trail is another, but again, a couple days after it opens it is closed due to the amount of animals taken, same for Glen hwy trails... Fairbanks areas have a lot of trails, but again, if there is a trail there will ogles of people already out there... I used to ATV a lot there, but not during hunting season, as it was not worth the success ratio, use your boots or hire a plane/air boat/jet boat. Much better option than an ATV for getting to hunting areas in AK.... Some of the big tundra buggies are pretty awesome, but an ATV isn't going to go anywhere the big boys go in those and their tracked vehicles... Anything north of the Yukon, no off road stuff... Be a long tow north to get really disappointed in access...
