We love the challenge of Whitney in terms of elevation gain, length and peak altitude.
Any others we should look at?
I don't think there are any trail hikes in California which will satisfy all three conditions, but there are several which satisfy the first two.
In Kings Canyon,
Granite Pass (21.5 miles RT, 6300 elevation gain) start at Roads End 5065 feet and climb to 10800 or so (there is several hundred feet of descent after Granite Lip before you resume climbing).
Kennedy Pass (24 miles RT, 6400 elevation gain) start at Deer Cove trailhead around 4400 feet and climb to the pass around 10800 (or so)
In Yosemite,
Clouds Rest (20 miles RT, 6000 ft gain) start at Happy Isles at 4000 ft and climb to 9920 ft.
In Sequoia NP,
Franklin Pass (about 18 miles RT, 4100 gain) start at Mineral King trailhead at 7800 ft and climb to the pass at 11800 feet.
Cactus to Clouds, Start in Palms Springs at the Museum at around 400 feet and climb to the top of Mt. San Jacinto at 10800 (or so). 15.5 miles each way. over 10000 feet of climbing and you can take the Tram down after descending about 5 miles and 3000 feet.
