Silver City isn't actually a "city." It is a ramshackle little collection of private cabins, a small store and an old lodge that sit just outside the entrance to Mineral King. The area was all outside the Park until several years ago when Congress added it to protect Mineral King Valley from proposed development. Some of the private cabins in Silver City, which was a private community until being added to the Park, have been made into a "resort" and are for rent. Have you looked at their website?

Some of the "chalets" at Silver City Resort are rather nice but they are live-stay places where you would bring your own supplies and linens, do your own cooking, cleaning and so on. There is a small restaurant at the little store that operates some days. My main objection here is that other than Mineral King Valley, there is really nothing to see or do there. Mineral King is beautiful, no doubt about that. Years ago, we climbed and hiked all over that area and loved it, partly because it was so remote and outside the Park. It is one of the few points on the western side of the Sierra where you can access directly to the high country in a day hike, as opposed to the east side where there are many such points. The thing is, you need to get out of the valley floor to really enjoy it and the hikes are steep and strenuous. The area along the road is pretty built up with private cabins and campgrounds. Nice for a half day visit to see the high mountains or a day hike up to one of the alpine lakes but not much else.

The Mineral King Road, which leads you from SR 198 to Atwell Mill, Silver City and ultimately Mineral King is long, windy and narrow, with no services. You actually have to leave the Park and drive almost all the way down to Three Rivers to find the road, then follow it back up to the entrance station and on to the "resort" area. IIRC, the speed limit is around 35-40 MPH and you won't be tempted to go faster. The road dead-ends in Mineral King and the only way out is back the way you came. This makes it a nice place to "retreat" to a cabin in the mountains for a rest, with nothing to do but kick back and relax. It is not a good base from which to explore Sequoia National Park. For that, you'd be better off in Grant Grove, Wuksachi Lodge or camping in one of the many campgrounds. The old lodge and tent cabins we used to use at Giant Forest have all been removed. For the Sequoia side of the dual park, you might be better off outside the Park in Three Rivers.
