Great Salt Lake State Park

The Great Salt Lake is the largest saltwater lake in the Western Hemisphere and one of the saltiest bodies of water on Earth -- and floating in it is a bucket-list experience for families visiting Salt Lake City. The lake's salinity (3-5 times saltier than the ocean, depending on location and water levels) creates enough buoyancy that human bodies simply cannot sink.

For kids, the floating experience is genuinely mind-blowing. They lie back in the water and pop to the surface like corks. They try to put their feet down and bounce back up. They attempt to swim normally and find the physics are completely different. It is science made tangible and hilarious.

Brine shrimp are the lake's most visible inhabitants -- billions of tiny, translucent creatures that kids can scoop up and observe. They are harmless and fascinating. Brine flies line the shore in summer but do not bite or sting; they are annoying but harmless.

Honest warnings for families: The sulfur/brine smell is real and can be strong, especially on hot summer days. Most people adjust within 15 minutes, but sensitive noses may struggle. The salt water is extremely irritating if it gets in eyes -- bring goggles or warn kids emphatically.

After swimming, salt crystallizes on skin and hair, causing itching and stiffness until you rinse off -- the state park has outdoor showers, but bring extra fresh water just in case. Use old swimsuits because the salt can damage fabric over time. Water shoes are essential because the lake bottom has sharp salt crystals and rocks.

The lake has been at historically low levels due to drought and water diversion, which has environmental implications and can affect access points. Check current conditions at the state park website before visiting.

Despite the caveats, floating in the Great Salt Lake is a unique, memorable family experience. Kids talk about it for years. The sensation of effortless floating in a landscape of salt flats and distant mountains feels otherworldly. Pair it with a sunset for extra magic.

Access is through Great Salt Lake State Park ($10 per vehicle) or Antelope Island State Park ($10 per vehicle, with hiking, bison herds, and beach access).
