Great location, super clean (and I mean super clean) bathrooms and showers. Free pumpout, free laundry, water and electric included, and awesome staff. I hate to recommend it because they have limited space and want to make sure I get a spot next time I go! Staff was friendly, attentive, and very knowledgeable about navigating in and out as the Merrimack river is very challenging. The only downside is that there is no locked gate between the dock and shore, but there is a lot of activity which basically polices the place. Lots of things to walk to and do; steps away from the park and great restaurants.
