This space is unique if nothing else. Sandwiched between the Charles and Memorial, the park offers a boat launch, a baseball diamond, an open field, an outdoor gym, and a pool. Great views of the surrounding Harvard landmarks and the river. Parking is decent and I've never had trouble getting a spot, but do bear in mind that there are schedules games and practices here. Kids soccer, baseball, and quidditch. Yes, you read that correctly. It's now a real competitive sport - I've seen it here with my own eyes... look it up.

Pro tip: restrooms are available in some kind of a museum building, but can be a very far walk (and hard to find), so plan accordingly.
