This is a really great route for cyclists who are going to the Continent or arriving from the Continent.
The N80 is a serious road to be cycling on as it is the principal link for the Ferry and routes north and west. Full of articulated lorries and quite dangerous as a result. Avoid it at all costs.
This route does just that and travels through some beautiful countryside. Once you turn off for Tinryland you avoid all Towns and all traffic until you come out at Ferrycarrig and back on the main Rosslare road for a relatively short distance to Rosslare.
The road from Fenagh on as far as Kiltealy is stunning on a fine day as you travel close to Mount Leinster and through the Scullogue Gap in the Blackstairs Mountains. Some great historical sites and a bit of climbing make this a favourite of mine.
