Thing to Do
Learn about Boston's "Wicked" High Tides
Boston Harbor Now
For thousands of years, Boston's coastline has been filled, moved, and transformed thanks to both human and natural interventions.
Learn about Boston's ever-changing coastline by following the High Tide Trail, a short 6-stop walking tour in downtown Boston.
You can also join our partners, the Stone Living Lab, for onsite programming at Long or Central Wharves in downtown Boston during King Tide, or "Wicked High Tide" events. See events on the Stone Living Lab's calendar.
Learn more about King Tides and why they happen here in Boston.
