Park City · With kids

The 2002 bobsled track and ski jumps, still in use. Grounds and museums are free; the bobsled ride, zip line and tubing are paid, with age and height limits.

Park City Mountain runs a gravity coaster on rails and a longer alpine slide through summer, plus a chairlift ride for those who just want the view.

A wetland boardwalk with a small hands-on science centre and a climbing wall, on the flats between Park City and Kimball Junction. Pitched at ages four to ten.

An indoor action-sports barn with foam pits, skate ramps and trampolines, plus outdoor tubing lanes in winter. Sessions are timed; ages six and up.

Town sits near 7,000 feet and the summits above 10,000 — expect broken sleep the first night. Both resorts take children into ski school from about age three.
