Casco Bay, Portland

Casco Bay, Portland

Casco Bay is a scenic inlet of the Gulf of Maine stretching from Cape Small in the east to Two Lights in Cape Elizabeth on the west. The city of Portland, Maine’s largest, lines the bay’s southern edge, with the bustling Port of Portland nestled within its waters.

Known for its many islands-often called the Calendar Islands due to the popular myth that there are as many islands as days in the year-Casco Bay actually contains between 136 and just over 200 islands.

Historic lighthouses such as Halfway Rock and the iconic Portland Head Light mark the bay’s entrances, guiding mariners into Portland Harbor, a busy working waterfront that welcomes cruise ships, cargo vessels, and oil tankers alike.

Beyond its maritime significance, Casco Bay and Portland offer rich cultural and culinary experiences. Portland has earned the title of “America’s Foodiest Small Town” thanks to its vibrant seafood scene and diverse ethnic cuisine, drawing food lovers from near and far.

The city also boasts a lively craft beer culture, with over 15 breweries crafting local favorites. Alongside its gastronomic appeal, Portland is a thriving arts hub, home to the Portland Museum of Art, which features works by internationally renowned and Maine-based American artists, as well as world-class performing arts organizations like the Portland Symphony Orchestra, Stage Theatre, and Portland Ballet.
