Four drumlins jutting out into Hingham Harbor, woodsy trails with great views of Boston Harbor & Islands as well as Nantasket. Most of the trails are old carriage paths, which are somewhat grassy; there's also a rocky section (Rocky Nook, haha) and some gravel paths. Lots of walkers, families.
Rt 3A, to Martin's Lane.
