Cavan town is 114 kilometres from Dublin and is served by Bus Éireann services from the capital (around 2 hours). There is no train station — the county lost its railway lines decades ago. By car, the N3 from Dublin is the main approach road.
Belfast is roughly 90 kilometres to the northeast, making Cavan a feasible stop on a cross-border journey. Dublin Airport is the nearest international hub, with good onward connections by road. Hiring a car in Dublin is strongly recommended for anyone wanting to explore the lakes and mountains of the wider county.
