Shore Diving Superior

[freedivernd]

I'm trying to line up backpacking/snorkeling trips around the north shore.. sounds like you might have some inside info that could be useful to me.  I'm not famaliar with the area at all but I'm hoping to get into some clear rivers (someone has told me they can be very tanic) and into superior, and doing some remote camping/backpacking as well.  I'm looking for good areas to combine the two hobbies...  I'd like to hike a bit.. do the snorkel.. maybe hike a bit more or not, setup camp, repeat.  Orm maybe if I get into great remote snorkel sight I'd setup camp and spend the time in the water. 
Any Suggestions greatly appreciated.. thanks,
Fred
