It's tough getting around Nelson w/o a machine. It can be done but difficult. IMO the lakes north end is somewhat easier to navigate on foot (road is closer to deeper water). I stay @ the Maltana but there are four other places which typically have rooms without having to call ahead.
We stayed at the Maltana...Nice and clean. The Minnow Man (Arlen Rammel) has a cabin near Sleeping Buffalo that he rents out. You can find his information over in the Reports section
There is a road that you can get basically around the whole lake anywhere you go its not much of a walk to find fish if you didn't have a machine... But the road on the back side of the lake can get drifty if there is a lot of snow.. chained up 4*4 can usually do it... Good luck..
Cornbread,I personally think its is one of the easiest lake around to access without a wheeler.I have gone up there multiple time with just the truck not wanting to pull a trailer 300 miles plus. The access on the south end is limited but there is nothing from the campground north that isnt within walking distance (with a little ambition)for whatever you want to catch. The road on the west shore can get iffy later in the year but when there isnt alot of snow you can cover alot of that place with ease. What are you looking to catch? Have spent many a night at the ole sleeping buffalo but anymore really cant beat the Maltana.
