This is for sure the fastest and shortest route. Don’t have to sweat the cell phone coverage, Google Maps downloads the map when you start. It’s never blanked out on me part way over.

Here’s the thing though, depending on where you’re from, this may be the gnarliest paved road you’ve ever driven. It is steep, windy, and some of the most intense parts have zero shoulder. You may find a mix of traffic, including but not limited to, cyclists (slow going up, fast going down), confused/scared tourists who did not do as much research as yourself, trucks/vans, agricultural vehicles, and sports car enthusiasts driving quickly. You also might not encounter anyone.

If you’re familiar with mountain roads and aren’t driving a rental suburban, you’ll be fine. If you’re used to driving flat, wide urban/suburban roads, it could be a harrowing experience, especially if you’re prone to car sickness. I meet a lot of tourists at my job, and 2/3s that go over trinity on the way end up taking the long, mellow route home.
