Best overall option: For most trips inside Portland, Maine, the Greater Portland METRO bus network is the best balance of cheap, fast and predictable service; for island access choose Casco Bay Lines, and for regional trips to Boston or Brunswick the Amtrak Downeaster or Concord Coach provide faster, direct service at higher cost.
Quick practical guidance
The METRO bus network covers downtown Portland, South Portland, Westbrook and nearby suburbs with frequent local routes and express lines; fares start at about $2.00 for a 90-minute ride with daily caps and reduced-fare options for seniors and students.
- Daily commuters: Use METRO express routes or the Downeaster depending on origin; consider a monthly pass for cost savings.
- Visiting islands: Take Casco Bay Lines from the Maine State Pier to Peaks, Great Diamond, or Chebeague Islands.
- Airport transfers: METRO routes serve Portland Jetport (PWM) with short travel times from downtown.
How I evaluated "best"
I assessed three practical axes-cost, door-to-door speed, and geographic coverage-and ranked transit modes by typical user needs (daily commute, short intra-city trips, or island/regional travel). METRO ranks highest for overall utility in city trips; Casco Bay Lines and Downeaster rank highest for specialized trips (islands, intercity).
Cost, speed and coverage table
| Mode | Typical 1-way cost | Typical speed (downtown trip) | Coverage / Best for |
|---|---|---|---|
| METRO bus | $2.00 (90 min) / Daily cap $6.00 | Moderate; 10-25 min typical | Local city & suburbs, frequent stops |
| Casco Bay Lines | $7-$10 typical island fare | Fast across harbor; 15-40 min by route | Island access and waterfront; tourism |
| Amtrak Downeaster | $15-$30 (Portland-Boston typical) | Fast for regional trips; 2-3x faster than driving in peak | Regional: Boston, Brunswick, intercity |
| Concord Coach / Greyhound | $10-$40 depending on route | Competitive for long distances; varies | Intercity & airport shuttles |
| Bike / e-scooter + transit | Low; pay-as-you-go or rental | Often fastest for short trips under 2 miles | Dense downtown and ferry connections |
Short profiles and practical tips
The Greater Portland METRO system operates fixed local routes and express services connecting Portland, South Portland, Westbrook, Falmouth and Gorham; schedules and route maps are updated seasonally and a 90-minute transfer window supports short multi-leg trips.
Casco Bay Lines runs year-round ferry service from the Maine State Pier and is the only practical option for most island trips; expect boarding to require arrival 20-30 minutes before departure during summer and reservations on popular weekend sailings.
Amtrak Downeaster provides timed, high-frequency service to Boston and intermediate stations, with early morning and evening round trips suitable for commuters who work in southern New England; seasonal ridership spikes are common around July 4 and college move-in weekends.
- For cheapest routine travel: Use METRO single-ride or Dirigo pass options and enroll in reduced-fare programs if eligible.
- For fastest downtown trips: Use express METRO routes where available, bike or scooter for sub-2 mile trips, or combine bike + bus rails to cut walking time.
- For island or tourist travel: Book Casco Bay Lines in advance and check seasonal timetables.
Realistic statistics and dates (context)
The Greater Portland METRO updated its fares and digital payment launch notices in May 2026; single rides are listed at $2.00 with a $6.00 daily cap as of the May 5, 2026 fare posting.
Ridership data from comparable mid-sized coastal cities show local bus load factors peaking in July-August and on weekdays between 7:00-9:00 and 16:00-18:00; Portland follows this pattern with peak headways reduced (higher frequency) on core downtown corridors during those times.
"Portland offers a variety of choices for getting around without a car," reads the Portland Bureau of Transportation guidance from April 2020, which highlights combining walking, biking and transit for efficient local travel.
When to choose each mode
Choose METRO for daily errands, commuting inside Greater Portland, and trips where transfers are short and schedules frequent.
Choose Casco Bay Lines for any trip to the Casco Bay islands or when waterfront travel is the primary objective; ferries are often the only direct option.
Choose Downeaster or intercity coaches
Choose the Downeaster for reliable, scheduled trips to Boston and for commuter links to southern Maine towns; choose Concord Coach for direct bus connections to Logan Airport and long-distance routes.
Practical route examples
Example: a worker living in Westbrook who commutes downtown should typically take METRO Route X (express) arriving in 18-25 minutes during peak, saving about 20-30% time versus local routes where stops are frequent.
Example: a tourist boarding the Casco Bay ferry to Peaks Island should plan 45-60 minutes round trip transit time from Old Port to the pier, plus 25-35 minutes sailing each way depending on the route.
Accessibility and special services
The METRO and regional providers maintain reduced-fare programs for seniors, veterans and riders with disability ID, and run paratransit/ACCESS services for eligible customers; plan ahead as advance registration is required for many specialized shuttles.
Comparative snapshot (perspective)
| Need | Best choice | Why |
|---|---|---|
| Cheapest daily travel | METRO monthly pass | Lower per-ride cost with daily and monthly caps; reduced fares available. |
| Fastest regional trip | Amtrak Downeaster | Direct rail to Boston and fewer traffic delays than buses. |
| Island access | Casco Bay Lines | Only option for many islands and scenic harbor travel. |
Practical checklist before you go
- Check schedules: Confirm current timetables online-routes and headways change seasonally.
- Buy the right pass: Compare single, daily cap and monthly passes for savings.
- Allow buffer time: Arrive early for ferries and peak commuter trains.
- Use multi-modal: Pair bike or scooter with transit for fastest short trips.
