You can find info on the FJ1200 page, I went from Sacramento up and over Hwy 50. It's a straight shot to Zion this way, but the ride itself is here:
Highway 50 - America's Loneliest Highway to
Zion National Park and then I did the return trip on
Highway 375 . The north rim of the Grand Canyon is really near, (I missed that) also if you venture a little further east, more national parks abound. Check out a Utah state map and look at all the green in that area of the SW corner of the state. However, if you head into Vegas, and then over to the Hoover Dam, and the
south rim of the Grand Canyon keep in mind it's a bit of a distance to circle around like that. First time through here, I headed down to Sedona, AZ afterwards and then swung around to San Diego and up the coast.
I will tell you I think out of all the riding I've done over the years, the ride across Nevada and back was one of the most unforgettable rides I've ever done. An intense moment of inner calm and solitude. Did the entire ride (2nd time there-back) in 2 1/2 days of non-stop riding- although I did have to drive a U-Haul back from Tonopah, NV with the bike in the back.
Although the weather in
South Lake Tahoe this time of year is a bit chilly. Doesn't look like snow though. Just remember, much of Nevada is the high desert. It's perfectly flat, but you're at 5000 feet in elevation. Dress acordingly. Elevations over the mountain ridges and be over 6000 feet.
