I'm planning a trip to yellowstone and will be driving a large RV and towing a vehicle from Los Angeles. Getting to Salt Lake City is a no-brainer, but then there are many different routes that lead to the park. What is the best/fastest way to get to the south entrance/w. thumb area. We want to avoid steep inclines and windy roads as much as possible.
Stick with 89 to Jackson going 15 to Idaho Falls and then over is way out of your way. I rode the route from Idaho Falls to Jackson and it is narrow and windy.
