Great Marsh Park is located on the Choptank River in Cambridge, MD. It's a fairly large city park and there is a launch ramp and docks for fishing. There is a also small sandy beach for wading or playing in the sand. The playground was recently upgraded with new equipment with a nature theme and interactive signs. There is a hollow tree "cave", a spinning mushroom with toadstool steps, "trees" for climbing, a giant bee and a giant ant with hollow ant nest, with a nice walking path connecting everything. There is also a traditional climbing/slide set in the middle. It is usually fairly clean and I've never had issues with any people here.This is one of our kids favorite playgrounds now. There is a pavilion with picnic tables, and there are some scattered trees for shade in the playground area.There is generally one "port-a-potty" bathroom in the area. The park is surrounded on three sides by the river, so it is somewhere you need to keep a close watch on kids who like to wander. This is also where they set off the fireworks for the 4th of July, so it's possible to get a clear view.
