Casco Bay Lines operates year-round scheduled ferry service connecting Portland to six island communities across the bay. Fares vary by destination and passenger type, with separate pricing for residents and visitors. This guide breaks down current ticket costs, explains the payment structure, and clarifies what's included in each fare category.
Quick answer
Adult round-trip fares to Peaks Island cost $16 as of 2026, serving as the baseline for Casco Bay Lines ticket prices. Longer routes to Chebeague Island, Long Island, and outer islands carry higher fares, typically ranging from $18 to $28 round-trip depending on distance. Children under five ride free, while youth and senior discounts apply on most routes. Tickets are sold at the terminal ticket window, onboard from crew members, and through the online reservation system for specific sailings.
Casco Bay Lines maintains one of the oldest continuously operating ferry services in the United States, carrying more than one million passengers annually across routes that range from fifteen-minute hops to Peaks Island to hour-long journeys to Chebeague. The fare structure reflects both distance traveled and the operational realities of serving year-round island communities, where ferries function as essential transportation rather than recreational excursions. Casco Bay Lines ticket prices follow a zone-based model tied to nautical miles from the Commercial Street terminal. Peaks Island, the closest destination at roughly three miles, anchors the lower end of the fare spectrum. Trips to Little Diamond and Great Diamond islands fall into the same price bracket. Longer routes to Long Island and Chebeague command higher fares due to extended travel time and fuel costs, while Cliff Island—the most distant stop—sits at the top of the published rate card. Resident fares are substantially lower than visitor rates, a tiered approach common among working waterfront operations where islanders depend on daily ferry access for commuting, groceries, and medical appointments. Payment options accommodate both walk-up passengers and advance planners. The terminal ticket window accepts cash and cards during operating hours, which begin at five in the morning to serve early commuters. Onboard purchases are possible when the ticket office is closed or lines are long, though crew members prioritize safe vessel operation over transaction speed during busy boarding periods. Monthly and ten-ride passes offer savings for frequent travelers, while group rates apply to parties of twenty or more with advance notice. Vehicle transport to Chebeague and Long Island requires separate freight barge arrangements and follows an independent fee schedule not included in passenger fares. Seasonal demand shapes the passenger experience more than the printed fare itself. Summer weekends see Peaks Island ferries fill to capacity, with standby lines forming an hour before departure during July and August. Shoulder-season visits in May or September offer the same route access at identical prices but with open seating and minimal terminal congestion. Winter service runs on a reduced schedule with fewer daily sailings, though fares remain consistent across all twelve months. The ferry system prioritizes island residents during peak times, meaning visitors may wait for a later departure if capacity is reached.
