We are a couple in our 60’s (well travelled) and plan collecting a hire car in Las Vegas beginning of March and taking the following route.
Las Vegas to Death Valley:-
US-95. NV-373. CA-127. CA-190
Death Valley to Barstow
CA-127. I-15 I-15 (S)
Barstow to Palm Springs
CA-247 Twenty Nine Palms Highway
Palm Springs to San Diego
I-215 (S) I-15 (S)
Also considering Palm Springs to Julian
Would appreciate info. on road conditions at that time of the year and if we are likely to encounter snow. Also any suggestions on preferred alternative routes. Many thanks.
