It depends on how much ground you want to cover. Assuming you take the ferry out of Burlington, you have plenty of decent choices of routes if you keep Lake Placid as the westernmost turnaround. Once you go west of Lake Placid, your committing to a much larger loop (not counting doubling back).

I've done multiple tours in the area, but never camped or spent a night in the area you reference (within the Ticonderoga, Lake Placid, Plattsburgh triangle.

OTOH - if you're looking for a larger loop you can start out north crossing the lake just south of the Canadian border, then working south and west. You can make a loop west to Saranac Lake, then a return through Lake Placid, and work south to cross back to VT.

IME, I found the riding south and east of Lake Placid nicer than to it's west, and would bend the trip southward to Ticonderog or even farther south then swinging back into VT.

I suspect hat you're behind the curve and it may be cold, but t least the roads will be much clearer of tourist traffic than during the summer.

Just keep in mind that road choices ( and all other choices in the off season) can be limited once you're more than a few miles west of lake Champlain.
