Those flowers can be reached by driving south from Carson City for about 40 miles south on a combination of U.S. 395, Nevada S.R. 88 and California S.R. 88 to Kit Carson Pass.
From the U.S. Forest Service paved parking area ($3 per vehicle) at the pass, you will walking on a hiking trail for a distance of about two miles at an elevation of about 9,000 feet.
Be sure to take it slow and easy and to carry a hat, sun glasses, sun screen, insect repellent, lunch, drinks, camera, lots of film and a light jacket.
On Saturdays and Sundays, you can expect to encounter large numbers of flower lovers, hikers, backpackers, fishermen, etc. on that trail.
