VIATOR SUCKS
This experience through TripAdvisor and Viator is totally misrepresented. The bike shop is excellent. You can go directly to the bike shop listed here in Killarney right across the street from Dromhall hotel
They give you a map and you have to figure out where you're going on the maps on your phone not worth $166 for the experience you could've done it for 90 viator company sucks
Easy, fun, amazing sights and scenery
Had a blast! The process of getting the bikes was super easy, directions to the place, not so much, but we found it. Even though it was a self guided tour, the guy at the bike shop gave us great recommendations and the path to the Muckross House and Gardens and the Torc Waterfall was fun and we saw some gorgeous scenery. The E-bikes were easy to use and got us everywhere we wanted to go.
