Sullivan’s on Castle Island reopens February 28, 2026, marking the start of its seasonal operations
Seasonal reopening returns to Castle Island after winter closure
Sullivan’s on Castle Island reopened for the 2026 season on Saturday, Feb. 28, with service beginning at 10 a.m. at the South Boston location. The reopening follows the business’s annual winter shutdown and restores a longtime late-winter tradition for residents and visitors who associate the stand’s return with the transition toward spring.
The 2026 opening came days after a major winter storm brought heavy snowfall to parts of New England, leaving large snowbanks and winter conditions in place as the first customers returned to Castle Island. Despite the weather backdrop, the reopening proceeded on schedule.
What’s on the menu and what customers can expect
Sullivan’s is known for classic counter-service fare served in a family-oriented, outdoor setting on Castle Island. The seasonal return typically brings high early-season demand, especially on opening weekend, when lines have been common in recent years.
- Hot dogs and hamburgers
- Crinkle-cut fries
- Seafood options such as clam strips and lobster rolls
- Ice cream
Operational details can vary by time of year and conditions, but the 2026 reopening restores daily service at the Castle Island stand, reactivating one of the city’s most visible seasonal food operations along the Harborwalk and the recreational paths around Fort Independence.
A multigenerational business with a growing footprint
Sullivan’s began in 1951 as a concession stand and has remained in the Sullivan family across multiple generations. While the Castle Island location remains its flagship and most recognized site, the business has expanded in recent years with additional outposts, including at Hub Hall and at Hanover Crossing on the South Shore.
The brand has also drawn national culinary recognition. Sullivan’s has been honored with a James Beard Foundation America’s Classics Award, a designation that highlights longstanding, locally rooted establishments with enduring community significance.
Why the reopening matters for Castle Island and South Boston
Beyond food service, the reopening functions as a seasonal marker for Castle Island’s busier months, when foot traffic increases and the waterfront becomes a hub for walkers, runners, families, and visitors. The stand’s return can influence weekend patterns in the area, particularly when temperatures begin to climb and daylight extends later into the day.
The 2026 season begins with Sullivan’s resuming service at Castle Island on Feb. 28, restoring a familiar winter-to-spring milestone on Boston’s waterfront.
Sullivan’s reopening arrives as the city moves from winter storm cycles toward spring conditions, reintroducing a staple stop along one of Boston’s most frequented shoreline recreational routes.
