Landmark · Hidden Gem · Tourist Spot
Agassiz Rock is a 116-acre (47 ha) park in Manchester-by-the-Sea, Massachusetts, that is owned and maintained by The Trustees of Reservations. The park's name is from two examples of large glacial erratic boulders plucked from bedrock. As glaciers scoured this landscape, the mass of bedrock forming the hill proved more resistant than the surrounding soil, forcing the bottom of the glacier up and over the hill. The north side was smoothed and the south side left steep and rugged as the glacier broke off chunks of rock as it passed.

Little Agassiz Rock is a granite monolith on one of the trails. It rests on a small jagged stone, leaving an opening below. A short distance away, other boulders lie perched on the edge of this glaciated upland. Below, in a small shrub swamp, rests thirty-foot-tall Big Agassiz Rock. Its depth is unknown.
The trail to the site is a one-mile loop that passes both Big and Little Agassiz rocks. Following long periods of rain the area surrounding Big Agassiz Rock often floods.

  • Happy we stopped! Can spend 20min - few hours here appreciating the peace! Be sure to ck out the Big & Little Agassiz.. both admirable!
  • Good hike to do with kids. 1-1/8mi up to Donovan’s Point on the blue trail via Small Agassiz Rock. Only complaint is that it’s super buggy!
  • Easy access and ample parking. The trails to the rocks are brief, but connecting paths offer much more length. I found the signage in some locations a trifle ambiguous and once off the main drag you need to channel your inner pathfinder. Big A came to a rest in a swamp so bring your boots.
  • Short hike for a good reward. Go there every day for my lunch break. Very peaceful
  • Fairly easy hike. Took about an hour to do entire route. Very well marked. Nothing too exciting to see but it's usually quiet here so it is a peaceful spot. Good stroll with a dog or post lunch.
