How much hiking do you do?

Have you dne Yosemite....it's best to do there and sequoia/kings canyon in the same trip.

Sequoia/kings canyon are a merged park...one entry does both. There is not park lodging there. There is some camping grounds. Yosemite has park lodging.

Would just use Fresno as a base and then use it to do sequoia for 2 days and then go up into Yosemite for 2 days.

Unless you do the long backcountry permit hiking you could do the park in 2-3 days at most. It's manly ne loop road from Fresno to Visalia that loops through both parks with a few spur oads off of there.

One option you could do is d 2 days in the park then go to the south and then come up 395 in he am and you could spend a night or two in the mammoth lakes area then come back through Yosemite throughtouloume meadows part over tioga pass.

You may find sMe renal cabins jus outside the park or o the north and south or n the east side ofthe erras.
