Good paddling in northeastern Mass.

Looking for quiet, low-key paddling in the area from Lynn to Gloucester. Not open ocean, and few or no power boats. Looking for ponds, lakes, or sheltered salt water. Anything quiet in that area, or is it all built up?

Rivers/estuaries
Danvers, Ipswich and Parker River basins. Just be cognizant of the tides. Cape Ann is a pain to find parking in the summer.
