On 30.5.2026, we rode over the pass in rain and fog with trekking bikes and full luggage. Very steep at the top, just managed without dismounting. Unfortunately, no visibility, but still an experience. When descending towards Portmagee, the Cliffs of Kerry are worth it, despite the 5 Euro entrance fee. And on Valentia Island, the detour (on foot) to Bray Head is recommended, where we suddenly had brilliant sunshine.
