Boise to Salt Lake City road trip stops: Three Island Crossing State Park

Three Island Crossing State Park, on the Snake River near the Glenn Ferry exit of the I-84 in Idaho, is a good place for hiking, mountain biking and camping. But it’s the cultural and historic aspects of this state park that make it memorable.

This was a key point on the Oregon Trail, partly because it was one of the easiest places to cross the Snake River.

Three Island Crossing State Park has self-guided trails taking in decades-old wagon ruts and replica wagons. The Oregon Trail History and Education Center, meanwhile, tells rich stories about the 19th century pioneers.

Boise to Salt Lake City drive: Shoshone Falls

Shoshone Falls on the Snake River in Idaho is taller than Niagara Falls and – particularly in spring – it rivals the more famous falls for power and water flow.

Near the town of Twin Falls, Idaho, Shoshone Falls drops over a 300 metre rim and kicks up a thunderous spray.

You can organise a Shoshone Falls tour from Twin Falls, or drive yourself and view the majesty from one of three viewpoints.

Boise to Salt Lake City road trip: Antelope Island

You’d be forgiven for thinking that Utah’s Great Salt Lake was something of a dead zone where nothing can survive, but Antelope Island in the middle of it is a surprising wildlife refuge. Thousands of birds cluster around the coastline, feeding on brine flies. But it’s the creatures on the island’s hillsides that tend to thrill visitors. Deer and pronghorn antelope compete for space with huge herds of chunky bison. The latter have a tendency to saunter across the road in front of your car…
