East Setauket features a mix of opportunities for walking, with some areas being more accessible than others. The region includes parks and trails, such as Avalon Park and Preserve and Frank Melville Memorial Park, which provide pleasant walking environments. However, the suburban layout and distances between key destinations may make walking less practical for errands or commuting. Sidewalks and pedestrian infrastructure are present in some areas, but they may not be consistent throughout the town. Seasonal weather, including cold winters and humid summers, can also influence the comfort of walking as a primary mode of transportation.

Vožnja biciklom u istočnom Setauketu praktična je opcija u određenim područjima zahvaljujući mješavini predgrađa i prirodnog krajolika. Regija obuhvaća neke biciklističke staze, poput staza i mirnijih stambenih ulica, koje mogu pružiti ugodno iskustvo vožnje. Međutim, dostupnost namjenskih biciklističkih staza ili opsežne biciklističke infrastrukture može varirati, a neke glavne ceste mogle bi predstavljati izazov zbog prometa. Udaljenost između ključnih odredišta na tom području također može utjecati na praktičnost vožnje biciklom kao primarnog načina prijevoza.

Public transit options in East Setauket are primarily provided by Suffolk County Transit buses, which connect the area to nearby locations. The S60/S69 bus routes provide access to neighboring towns, including Stony Brook. While public transportation is available, the region’s suburban layout may make it less convenient for reaching some destinations directly. Walking distances to bus stops and the frequency of service could influence its practicality. Additionally, the Long Island Rail Road (LIRR) offers train service from nearby Stony Brook Station, which can be useful for longer trips.

Ferries are a transportation option near East Setauket, particularly through the nearby Port Jefferson ferry, which connects to Bridgeport, Connecticut. Operated by the Bridgeport and Port Jefferson Steamboat Company, this ferry runs hourly and accommodates pedestrians, cars, and bicycles. The journey typically takes about one hour, making it a practical choice for cross-sound travel. However, the ferry primarily serves as a regional connector rather than a local transit option within East Setauket. Accessibility to the ferry terminal and weather conditions may influence its suitability, especially for those relying on local infrastructure to reach the port.
