FAQs about flying to Idaho

What is good to know if travelling to Idaho?

  • There are many hot springs throughout Idaho, but the most famous are the pools at Lava Hot Springs in the southeastern corner of the state. The waters here are thought to have been 110 degrees for the past 50 million years. The springs are a popular holiday spot – as well as the hot pools there is an Olympic-sized swimming pool, massage or tube rides on the Portneuf River.
  • Idaho has some stunning scenery and vistas – desert plains in the South, mountain ranges and lava rocks in the East and gorges and thick forests in the North.
  • Labor weekend sees the Wagon Days festival in Ketchum: a celebration of the city’s mining heritage. The festival sees four days of celebrations hit the sleepy town, including a shoot-out, a fiddler’s contest, a rodeo and the Big Hitch Parade.
  • Boise is known as the City of Trees and the capital is surrounded by green land. Golf is very popular round the city: more than 20 golf courses are within a short drive.
  • If you want to take a drive to see some of the fabulous outdoors, head for the Bone Road. This “road” is little more than a track, covered in potholes, but its 60-mile span affords views of some of the best Idaho landscapes and you’re almost guaranteed to spot some wildlife like moose or deer.
  • Silver City, just outside Boise, is known locally as the “ghost town”. The town was once the site of a silver mine for the War Eagle Mountain. Today, its old houses and saloons are popular with photography workshops.
