Bicycling

O'Sullivan's Cycles. A bicycle is the perfect way to enjoy Killarney's mild air, whether within the confines of the national park or farther afield in the Kerry Highlands, and O'Sullivan's (opposite the tourist office) is a top place to rent bicycles–-classic, hybrid, or e-bikes–-for either the day or the week.
