Kick back on a (small) sandy beach with views of the Red Mountains on this mellow stroll to a backcountry lake. You’ll hike over the Continental Divide, through lodgepole pine forest, and past meadows where elk and grizzly bears often graze. Riddle Lake itself is a picturesque lake dotted with lily pads and is sometime home to nesting trumpeter swans. The trail is closed to hiking until July 15 because of bear activity; it’s smart to hike in larger groups after that, too.
