reality check.....from someone who knows those southern nevada highways well. i've spent many a winter in death valley.
to get from 95 to 395 is NOT a half hour. first tip--DON'T try to get to 395 via Death Valley and highway 136. very curvy and SLOW. scenic as fuck, but slow.
best way to go is this......drive up 95 to nevada 264. that's the intersection where the good ole cottontail ranch is (it's now falling apart in the desert.....sad!) turn left there. you'll head west until you hit Cal 168, which is the road to Big Pine and the junction of 395. total travel time, from Cottontail Ranch to Big Pine.....90 to 100 minutes. it's a nice drive, for sure. but think about it. in the time it takes you to go west to big pine, you'll be about 40 miles north of tonopah on 95, about 200 miles from reno. so really....is it worth it?
from Big Pine, you're 220 miles from reno. so actually, yeah, it might be worth it! if you wanna see some new country....and there ain't no gettin' around it.....395 from Big Pine to Reno is one of the GREAT scenic highways in America. just gorgeous Sierra Nevada scenery. you're driving from Bishop (4200 feet above sea level) to Mammoth Lakes area (8,000 feet) and the back side of the mighty Sierras.....all on a highway that allows speeds of 80 mph, easy. you'll go past Mono Lake, Bridgeport, Walker River Canyon zone.....fucking stunning country.
