I will agree that the public access on snowbank can be pretty tight for parking a truck and trailer on the weekends during trout season, especially on opening weekend. The folks at Snowbank Lodge are great people and are as accommodating as can be when it comes to helping people access through their establishment. Make sure to throw them some cash if accessing through their property. They indeed are not plowing a road out onto the lake this year but they have a couple of snowdogs for rent this year if anybody wants a unique way to get after Snowbank lakers.
I also offer a unique way to fish lakers in the Ely area, including Snowbank Lake with fully guided half and full day trips in my SnoBear.
