Road trips are great during the summer and an excellent way to see roadside attractions! If you’re looking for the best route, try I-15 N through Los Angeles, Las Vegas, Salt Lake City, and Twin Falls.
Here are the details:
  • Take Broadway to CA-163 N/Cabrillo Fwy
  • Follow I-15 N and I-84 W to Broadway Ave in Boise. Take exit 54 from I-84 W
  • Continue on Broadway Ave. Drive to S Capitol Blvd.
Here are some great ideas for stops along the way:
  • The Living Desert Zoo and Gardens in Palm Desert, California
  • Red Rock Canyon National Conservation Area in Las Vegas, Nevada
  • Grand Canyon Skywalk in Peach Springs, Arizona
  • Valley of Fire State Park in Overton, Nevada
  • Temple Square in Salt Lake City, Utah
  • Shoshone Falls Park in Twin Falls, Idaho
Looking for the quickest route between San Diego and Boise? Take I-15 N and US-93 N, which covers 954 miles in roughly 14 hours and 49 minutes.
