You can take the Tioga Pass over the Sierras!
Yosemite Valley is still closed, but you can get to the 120 via the 140 (hopefully Marmot will update us on YARTS). I believe they are diverting cars from the 140 onto the 120, which means you can use either the North or the Arch Rock (middle) entrance to YNP to get to the 120 and the high country.
Hikers posting on other forums yesterday said views and air were mostly good in the high country, with winds being the key factor.
Air Quality in the Valley is still unhealthy but moving closer to being "moderate" in terms of both pollen and particulates.
A person driving west on the 120 to the 140 would get views of the Valley (and someone driving the opposite direction could certainly stop at a viewpoint to see the views). Things are still hazy.
