Yup. Bring your snowshoes and away you go. A good idea to download this trail to your GPS so you know where you are at. If you stay off the Mt. Washington snowshoe trails to Helen McKenzie you don't have to pay anything. Have fun.
I've been from Battleship & Helen McKenzie up as far as Croteau. You're likely to be cutting your own snowshoe trail through deep powder, so it can be a pretty good workout. GPS track is highly recommended, unless you know the area really well. I found the snow to be a bit disorienting since the usual landmarks are hidden.
Lots of fun and absolutely scenic back in there this time of year!! Make sure you're prepared and bring along your safety equipment!
