The InterRail website https://www.interrail.eu/en/interrail-passes/one-country-pass/ireland seems unclear as to whether Ireland passes are valid in Northern Ireland. It sttes 'The Emerald Isle is a small island of dazzling contrasts with its own soundtrack, from lively Dublin bars to rugged rocks, impressive mountain ranges, and kissing stones. Visit Belfast, Blarney, Limerick, and Waterford.'
The Belfast reference clearly implies cross-border validity. However, further down it states '
Can I cross the border?
Not with this Pass, as it’s all about exploring one country from top to bottom. Want to cross the border? Go for a Global Pass.'
When you click 'Learn More’, it gives the example: 'The Pass is valid for travel only in Spain and cannot be used to travel from the Netherlands to Spain'.
The island of Ireland has two countries in it-the Republic of Ireland and the UK in the form of Northern Ireland. Yet the reference to Belfast above suggests that the pass is valid in both parts of the island.
Can anyone clarify the position?
