Might depend on your speed, but...
Assuming you're starting on the Wicomico River, try Solomons -- any of about 5 good marinas
, we usually stay at Zahnisers.
If you're too slow to do that in one leg, try anchoring
Bay or Fishing
Creek, not far from Blackwater Refuge.
, any of about 10 decent marinas
in Spa Creek or Back Creek.
If you're too slow to do that in one leg, try Deale, any of 3-4 good marinas; we usually prefer Herrington Harbor North. Herrington South could be an OK alternative.
