Grand Targhee has an unusual approach to the paid parking location. Not sure if they started the idea this season or last season.
Lot 1 is next to the base. On Fridays, Saturdays, Sundays, and holidays, there are some rows in Lot 1 roped off for paid parking. Have to enter next to a little hut to pay $20. The number of rows varies. What is unexpected is that the first 3-6 rows are left as free parking for the early birds. Then there is the pay section. Then a few more free rows.
On a Friday powder day, the free rows in Lot 1 can be gone by 8:15. I know because my ski buddy and I got the last space on March 3. Only because 2-3 cars in front of us decided they weren't going to make it so turned off to make sure they got a space in the farther free rows of Lot 1. There was 8+ inches of fresh fluffy snow after lifts closed the afternoon before and it was still snowing hard that morning. On Saturday morning, there were several more paid rows. We got there quite early and parked in the second row. Only three of the closet rows were free that morning.
There are three more parking lots, plus some overflow space. There are shuttle buses for the other lots. However, apparently there are times when all the parking fills up. There are shuttle buses from town, which I think are free.
Grand Targhee paid parking on a Saturday powder day, before 8:00am
Entrance is next to the hut in the back corner where they take the $20, overnight guests can park in that area for free
