Are there many supermarkets before entering Yosemite? I need to stock up on water and snacks at a reasonable price. I am coming from SF.
If you're a Costco member, you could stop at Costco either in Tracy or Manteca; both are near the highway so would not be too far off your route. If not, there are grocery stores in both towns. In Oakdale there is a Raley's, Save Mart, Grocery Outlet and Ralphs. There are also a couple of food stores in Groveland. In Yosemite Valley there are food stores both at Yosemite Village and Curry Village.
Thank you for the suggestions. Yes, I am a Costco member and we may pay a visit there.
Just a note: if you are staying within the Yosemite Village...
Costco sells things in bulk. Packages are usually huge. You may want to buy extras, more than you need for this trip, and save the rest for home. But remember the bear policy in Yosemite - all food and even water cannot be left inside the vehicle. You would need to haul them all, I mean all, to the anti-bear food lockers at your cabin. You may need to make extra trips to do that. Thought you may want to keep that in considerations when you make your purchases.
If PattyJ is staying in hardsided lodging (Yosemite Lodge at the Falls, for example), she can bring all the food & water into her room. If she's in a tent cabin or camping, she'll need to use her bear locker.
There was a campground review posted this summer from a TA member who was unhappy that the rangers reprimanded her several times a day about leaving a cooler out that just had water bottles in it; she had too much stuff for her bear locker. I was surprised that the rangers didn't ticket her.
I didn't know about the bear policy. I better tell everyone to clean up the snacks in the car. We are staying at the Ahwahnee. Thank you for the information.
Glad you found out now. Trying to find stray wrappers and empty cups in the dark isn't fun. Here is some additional bear information: tripadvisor.com/Travel-g61000-c159048/Yosemi…
