Jackson Hole · With kids

A ten-minute crossing saves two miles each way and lands walkers below Hidden Falls, half a mile up a rocky path. The boat itself thrills most under-eights.

Nine minutes to 10,450 feet, waffles at the top hut and a short summit loop. Cold and windy even in August; take a jacket regardless of the valley temperature.

On the hill above the elk refuge, with a children's discovery gallery and a sculpture trail outdoors. Good for a wet afternoon; ages four and up.

Horse-drawn sleighs go out among thousands of wintering elk from late December to early April. Blankets provided; it is properly cold, so overdress.

Town sits above 6,200 feet and trailheads higher — expect slow first days. Carry bear spray on any trail, and be off ridges before afternoon thunderstorms build.
