Distance from Calais, Maine to Charlottetown, PEI: ~165 Miles

The straight-line distance between **Calais, Maine (USA)** and **Charlottetown, Prince Edward Island (Canada)** is approximately **165 miles (266 km)**. However, the actual driving distance is significantly longer due to the geography of the Gulf of Maine and the requirement to cross into Canada via land borders.

Driving Route & Distance

The most practical all-land route:

1. Calais, ME → Woodstock, NB (border crossing + Trans-Canada Hwy 2): ~65 mi / 1 hr 15 min
2. Woodstock → Moncton, NB (Hwy 2): ~120 mi / 2 hrs
3. Moncton → Confederation Bridge (Hwy 16 → Hwy 1): ~55 mi / 1 hr
4. Bridge crossing (12.9 km toll bridge): ~15 min
5. Borden-Carleton → Charlottetown (PEI Hwy 1): ~35 mi / 45 min

Total driving distance: ~275 miles (440 km)
Estimated drive time: 5–5.5 hours (plus border processing time)

Key Considerations

• Passport or enhanced ID required for U.S.–Canada border crossing at Calais/St. Stephen.
• Confederation Bridge toll (collected leaving PEI): ~$50 CAD for standard vehicle.
• No direct ferry from Maine to PEI; the CAT ferry runs Bar Harbor–Yarmouth, NS (seasonal).

While "as the crow flies" it's 165 miles, the road trip nearly doubles that distance—plan accordingly.
