About County Mayo
Why explore County Mayo
Westport provides rail, buses, accommodation and food, making it the practical first base. Give the town its own time instead of treating it only as the start of a drive.
From Westport, choose Achill, Clew Bay or an inland landscape for one full day. Crossing several parts of the county turns the visit into road time.
Plan the region
Westport is the easiest first base, while Achill and the wider coast need separate days planned around weather, road time and limited public transport.

A practical first visit
Westport is the easiest first base, while Achill and the wider coast need separate days planned around weather, road time and limited public transport.
Link the stops sensibly
Routes and day trips
Atlantic wind, rain and cloud can change beaches, viewpoints and mountain routes quickly. Keep the clearest day for the most exposed coast and save a town or heritage plan for poor visibility.
Suggested regional routes
Westport
One or two nights suit the town itself, while a longer stay makes Westport a useful base for Achill, nearby coast and carefully chosen outdoor routes.
Open destination guideAchill Island
The island needs at least one full day from a local base, while two or three nights give weather flexibility and reduce the pressure to race between distant viewpoints.

When to visit
Trains and coaches reach Westport, with buses and Local Link services covering selected communities. They do not form a frequent sightseeing loop around the county.
A car gives the greatest flexibility but roads can be narrow and slow. Four days suits Westport and one coastal area, while a week supports two bases without daily backtracking.
