When Boise's temperatures soar in summer, several thousand people can float the downtown stretch of the city's namesake river in a single day.
For a nearby, uncrowded alternative, try the waterway's Eagle Island route, about 6 miles west of downtown Boise. Within minutes, floaters trade the buzz of traffic for the gentle rush of the river flowing past willow trees, as red-winged blackbirds dart overhead and weasels scamper along the banks. After your refresher, drive on to Eagle and browse the shops in the town's historic district.
