For the most up-to-date Highway conditions, visit Caltrans. Check for possible additional advisories from the Park Service. To view conditions in the park in real-time visit the Yosemite Webcams.
To avoid winter driving in Yosemite you can take YARTS (Yosemite Area Regional Transit System). YARTS service begins in Merced and stops all along State Highway 140 in the winter, picking up at hotels in Mariposa, Midpines, El Portal, and in Yosemite National Park. Stay close to the park (but below the snowline) and take the YARTS into the park for a stress-free way to explore. Once in Yosemite there is a free shuttle that has frequent stops throughout the valley floor.
Chains are sometimes required in the park. Check the road conditions in advance by calling 209/372-0200 (press 1 then 1). You can bring them with you or rent them outside the park in the town of Mariposa.
Driving through Yosemite can be an amazing experience, although in heavy traffic, the scenic routes may not be a peaceful drive. Schedule to enter the park at non-peak hours by viewing the NPS Traffic Forecast. Driving tip – during the busy summer months, the best time to drive through the park is before 10.00 am or after 4.00 pm.
When traveling into Yosemite, it is important to check the Yosemite weather conditions especially during the winter season.
