If you're deciding where to spend an afternoon outside, here's what's documented about three options near Bloomingdale: Silas Condict County Park in Kinnelon, Pyramid Mountain Natural Historic Area in Montville Township and Independence Park in Riverdale.
Two of these are Morris County parks with detailed acreage and trail information on file. The third, Independence Park, has a borough page that confirms the address but not much else, so we're not going to fill in the blanks.
