You want crazy blue water North Beach sits right at the top edge of Bear Lake along the Idaho border. The water looks fake. It glows this bright turquoise because of crushed calcium carbonate floating up from the deep lake bed. You can walk out two hundred yards and the water still barely covers your knees. It's safe for kids. Perfect for lazy floating.

When the midday heat fries your brain, drive ten minutes to snatch a famous local fresh raspberry shake.
