So, let’s break down the different routes you can take, the distances involved, the time it’ll take to get there, and, of course, the gas prices that will impact your wallet.

Route 1: The Scenic I-70 and I-15 Loop

  • Time: You’ll spend about 16 hours on the road here as well.

With gas prices staying at $3.80 per gallon, you’d again be looking at needing approximately 43.2 gallons of gas. This brings your gas costs to around $164.16.
