Frequently Asked Questions
Do I need chains on Angeles Crest Highway?
During winter storms, chain controls may be active on SR-2. However, most Mountain High visitors use I-15 through Cajon Pass to SR-138 instead, which rarely requires chains. Angeles Crest is scenic but challenging in winter.
Is Angeles Crest Highway open in winter?
The upper section of SR-2 (above Islip Saddle) frequently closes in winter. Caltrans often closes it preemptively for storms. Check current status before planning this route.
What is the best way to get to Mountain High?
Take I-15 north through Cajon Pass, exit at SR-138, and follow signs to Wrightwood and Mountain High. This route avoids Angeles Crest Highway entirely and is faster, safer, and rarely has chain controls.
What is R1, R2, R3 chain control?
R1 means chains required except for vehicles with snow tires or AWD/4WD. R2 means chains required except AWD/4WD with snow tires on all four wheels. R3 means chains required on ALL vehicles. R3 usually precedes highway closure.
