While the waters of the massive Great Salt Lake are too salty to sustain anything more than algae, brine shrimp, and brine flies, the wetlands on its north and east shores are critical habitats for millions of migratory birds, making it a top-notch bird-watching destination. There are three state parks adjacent to the lake, including the Great Salt Lake Marina, where you can launch sailboats and kayaks. And if the water level is low enough, you’ll be able to see the famous Spiral Jetty, a 1,500-foot-long art installation made of salt-encrusted basalt slabs.
