The JMT is your ticket to endless views like this, though the landscape is slightly different once you leave Yosemite proper. There are bigger alpine mountains, more lakes, and less dense forest. It's just as epic.
For stuff shorter than the JMT, the Sequoia / Kings Canyon National Park backcountry is incredible with easy access. I'd suggest you look into Rae Lakes Loop. The beautiful views are highly concentrated, just like Yosemite Valley, expect remote and tourist-less.
👇 The JMT takes you through the heart of ALL the Sierra granite, including all the national parks there: Sequia, Kings and Yosemite. That's why it's so special. And the SEQKI backcountry is by far the most remote area of the Sierra.
