Our best estimate, which is highly dependent on traffic and road conditions, is the ride from Reno to Gerlach will take 2-3 hours and from San Francisco it will be 6-7 hours to Gerlach.
From Gerlach, it is probably 1-2 hours to Black Rock City. You will be expedited through Will Call, the Gate and Greeters; please keep in mind there is a 10 mph speed limit on Gate Road. Once your bus reaches Gate Road, the AC will be turned off for the remainder of the journey.
Travel times will be longer on the heaviest traffic days of Sunday and Monday.
