Whale Watching on Cape Cod — Why Leave from Chatham?
Most Cape Cod whale watching departs from the Upper Cape or Provincetown — but Chatham sits at the elbow of the Cape, with fast access to the offshore waters east of Monomoy where whales feed in season. Instead of a big boat with hundreds of passengers, our trips run as private charters for up to 6 guests: your own captain, your own schedule, and a trip of about 3.5 hours shaped around that day’s conditions and wildlife activity.
Along the way you’ll pass the Chatham fishing fleet, seal colonies, and some of the most striking coastline on Cape Cod — so even the ride out is part of the trip.
