Two Hour Lighthouse Bicycle Tour from South Portland-Mellow
Best for: travelers who want an active, land-based outing with lighthouse stops
This is the most active of the three options and stays on land the whole time.

The route description emphasizes biking along a trail and some quiet roads, then returning to the starting point. It includes use of a bicycle and a helmet, and the listed departures are earlier in the day or mid-afternoon. Choose this if you want a compact sightseeing outing with clear stops and a straightforward ride format.
Why choose this bicycle tour

Guided RIB Boat Adventure of Portland
Best for: travelers who want a fast-moving boat ride with wide Casco Bay coverage
This option is built around covering more water in a shorter time. It departs from Portland Harbor on a 14-passenger RIB boat, which keeps the group small enough for everyone to have a forward-facing view. The description highlights a mix of lighthouses, historic forts, wildlife, birds, and the working waterfront, along with stops for photos. It also notes a local captain who guides the trip and answers questions. If you want a lively boat ride that emphasizes variety and a broad look at Casco Bay, this shared tour is the most direct fit among the three.
Why choose this RIB boat adventure
- The 14-passenger boat gives everyone a front-row view.
- The route is designed to show a broad range of bay sights in one outing.
- Includes bottled water and a cooler with ice.

Sunset & Scenic Private Boat Tour of Portland & Casco Bay
Best for: small groups that want a private, slower-paced boat outing with flexible departure times
This is the most intimate option and is designed for small groups. The private charter allows up to five guests and runs for about two hours, with departures listed for late morning, late afternoon, and sunset. The itinerary mentions touring Casco Bay islands and viewing the Maine coast, with references to Portland Head Light and the wider bay area. Because it is private, it suits travelers who want a quieter experience and more space for their own group. The included onboard items also make it easy to settle in for a relaxed cruise, while food and beverages are not included.
Why choose this private boat tour
- Private charter format keeps the outing limited to your own group.
- Offers a sunset departure as well as earlier daily times.
- Provides onboard towels, blankets, water, plates, ice, and cups.
How to choose the right Portland itinerary style
