1. Abraham Lake
As winter temperatures at this Canadian Rockies lake plunge to minus-30 Fahrenheit, methane gas from decaying organic material at the bottom takes on an ethereal formation. By the millions, bubbles stream upward and freeze fast in the ice. The result is a hard-frozen lake top with constellations of glassy orbs suspended underfoot — a gorgeous sight with an edge of danger, given the flammability of the gas. After the thaw, this vast sapphire lake remains stunning in summertime.
Don’t leave without: Getting a few snapshots. The curious phenomenon of the frozen bubbles is catnip for photographers.
2. Western Brook Pond
Newfoundland and Labrador
The 10-mile-long Western Brook Pond in Gros Morne National Park, on the western edge of Newfoundland, is a natural masterpiece — and just getting there is an adventure. From St. John’s, the only major city on the island, drive eight hours. Then hike two miles to access the boats that will take you out on the pristine lake waters for incredible views of cascading waterfalls, billion-year-old cliffs, and the Long Range Mountains.
Don’t leave without: Spotting wildlife along the hike and in the waters: bald eagles, whales, caribou, seals, and foxes
