Sleep at Azalea. It is the campground right at Grant Grove, open all year, and it is what turns the trip from a long day of driving into a morning walk under the big trees. From May through October the sites go on Recreation.gov up to four months out, so book the site first and the van second.
Then give the sequoias two full days. General Sherman stands at the end of a paved half-mile in Giant Forest, the biggest living tree on earth by volume, and General Grant anchors the Fresno side of the parks on a short loop up in Grant Grove. Come up Highway 180 to the Big Stump entrance, the route meant for longer vans, not the tighter Highway 198.
Giant Forest, Grant Grove, and Moro Rock
The walking in both groves is flat and paved, which is exactly what you want after a day in the van. Off the Sherman trail, the Congress Trail is a two-mile paved loop through the densest stand of big trees in Giant Forest; up at Grant Grove, a third-of-a-mile loop passes the Fallen Monarch, a fire-hollowed trunk you can walk straight through. Stay on the pavement, since the shallow roots are what hold these trees up.
For the long view, climb Moro Rock, a granite dome with a stone stairway of more than 350 steps and the Great Western Divide spread out to the east. On summer weekends and holidays its road closes to private vehicles and a shuttle runs from the Giant Forest Museum instead, and single vehicles over 22 feet are barred year-round, so ride in or come midweek.
Crystal Cave is the one detour worth half a day, a marble cavern on a half-mile guided loop that holds around 50 degrees while the groves warm up outside. Buy the timed ticket online well ahead, a day out at the very least and better weeks out, because they are never sold at the cave and the access road bans anything over 22 feet, so you park up top and walk the last half-mile down.
Nights up in the grove stay cool even when the valley floor is running near 97. Lock food and anything scented in the site's bear box around the clock, and keep generators to the 9-to-9 window. Fill the tank in Fresno or at Hume Lake before you climb, because there is no gas or charging anywhere inside the parks.
Kings Canyon Scenic Byway and Cedar Grove
When that road is open, keep driving past Grant Grove. Highway 180 drops off the rim into Kings Canyon itself, one of the deepest in the country, and bottoms out among granite walls at Cedar Grove.
Zumwalt Meadow is an easy walk under those walls along the Kings River, Roaring River Falls is a five-minute paved path to a whitewater chute cut through granite, and Roads End sends the eight-mile round trip out to Mist Falls for anyone who wants a real hike. Sentinel Campground sits right in the village with a bear box at every site and no hookups, same as Azalea. It only works in season, though. The road down to Cedar Grove is gated once the snow comes, so plan this leg for late spring through fall.
Shaver Lake, the valley-heat weekend
For a hot weekend without the long round trip to the parks, run up Highway 168 out of Clovis to Shaver Lake instead. It is a pine-shored reservoir at 5,500 feet on a different, shorter road than the sequoias, and it is the escape Fresno and Clovis actually make when the valley bakes. Dorabelle Campground sits just off the highway near the water; as of August 2026 it opens May through October, takes vans up to 40 feet, and has no hookups. It is not a national park, but that is not the question you are asking on the worst afternoon of the week.
A campervan sleeps two or three; if you need more beds, size up to a California RV rental. If you would rather aim north, Highway 41 out of Fresno is the approach to Yosemite's south entrance, which is its own trip with its own base at Yosemite campervan rentals. The California campervan hub rounds up the rest of the state's Sierra bases.
