Fodor's Expert Review Swords Rimrock Park

This trail system on the northern edge of Billings is a pleasant mix of paved urban paths and rugged dirt tracks, where elderly locals out for a Sunday stroll are just as content as extreme mountain bikers. Several individual trails make up the Rimrock system, which starts at Boothill Cemetery and winds past the airport up into the rocky formations that surround the city and give the trail its name. Expect fantastic views of the open plains and five distinct mountain ranges in some places, and the roar of jet engines and the sight of oil-refinery smokestacks in others.
