As America’s national parks strain under increased demand, the famously popular Yosemite National Park is doing something about it. Rush Creek Lodge at Yosemite is the first major new lodging in living memory, and it’s clear at a glance that it’s a new and perhaps ever so slightly more upscale era for National Park lodges — at least ones within driving distance of San Francisco. The rooms aren’t aggressively overdesigned, but they’re clean-lined and contemporary, while the villas split the difference between hotel suites and vacation homes. Rush Creek’s spa is an unexpected treat, and the restaurant, too, goes above and beyond typical park-lodge fare.
