Butterbaby and rtrw.

Difficulty - pretty easy
Time - drive up and a short stroll
Directions to starting place - Route 149, Deering, New Hampshire

Details you should know -
If a picnic is included in your plans for the day, there are tables
at the beach. I love this spot, but I use the term beach loosely.
You can swim here, but it's small. The Family paddles kayaks on this
lake.
