Mulligan Harbor marks a fresh chapter on the water. With a new name, a refreshed food and drink menu, and new ways to gather in every season, the harbor keeps the same familiar location now with more to come back for.
MAY – SEPTEMBER
Summer at Mulligan Harbor brings a few meaningful updates: four bars, a refreshed food and drink menu, and new golf simulators, along with a new name at the dock. The setting stays familiar but now there are more ways to enjoy it once you're here.
