Lake Matheson, New Zealand
At Lake Matheson, near Fox Glacier, nature has combined exactly the right ingredients to create truly stunning reflections of New Zealand's highest peaks - Aoraki (Mount Cook) and Mount Tasman.
The waters of Lake Matheson are dark brown, so on a calm day they create the ideal reflective surface. The colour is caused by natural leaching of organic matter from the surrounding native forest floor. By a happy coincidence, the mountains to the east are perfectly positioned to reflect in the lake.
An easy walk passes over the Clearwater River suspension bridge, just a few minutes from the car park. The Clearwater River drains off the lake and is brownish under the bridge, however it quickly becomes clear and true to its name. The track continues through ancient native forest, including tall rimu and kahikatea trees, to a pontoon that extends out onto the lake.
Long finned native eels thrive in the darkness of Lake Matheson, which is also home to many water birds. For this reason the lake is a traditional mahinga kai (food gathering place) for Maori people. Lake Matheson was formed about 14,000 years ago, when the Fox Glacier retreated from its last major advance towards the sea and left a depression which later filled with water. The walk from the car park takes 40 minutes to the pontoon, or 1.5 hours around the lake.
Lake Atitlán
Lake Atitlán rests at the foot of massive conical volcanoes. Nearly a mile up in the highlands of Guatemala, Atitlán (Lago de Atitlán) rests at the foot of three massive conical volcanoes. Small Mayan villages line its shores, which are set off by steep hills draped with oak and pine trees and nearly 800 plant species. There's no single, must-see view of the lake, so try several vantage points: from up high on Highway 1; from the town of Panajachel, the buzzing market hub that juts out into the water; or aboard a lancha, one of the many small boats that ferry visitors from village to village. We're saddened to note that the lake has built up high levels of blue-green algae over the years. However, much effort had made to solve the problem.
Peyto Lake, Canada
Alberta's Lake Louise is the famous one, on all the postcards and posters. But Louise's sister lake 29 miles north along Icefields Parkway, a two-laner that winds 142 miles through the Canadian Rockies, is even more picturesque. Thanks to glacial rock flour that flows in when the ice and snow melt every summer, the waters of Banff National Park's Peyto Lake are a brilliant turquoise more often associated with warm-weather paradises like Antigua and Bora-Bora. For the most dramatic views of the 1.7-mile-long stunner, encircled with dense forest and craggy mountain peaks, pull into the lot at Bow Summit, the parkway's highest point, and follow the steep hike to the overlook
Crater Lake
Thousands of years ago, the top of a 12,000-foot-high volcano in the Cascade Range exploded. The massive pit left behind became known as Crater Lake, the centerpiece of a national park in southern Oregon that displays nature at its rawest and most powerful. Forests of towering evergreens and 2,000-foot-high cliffs surround the lake, where extraordinarily deep waters—at 1,943 feet, it's the deepest lake in the United States—yield an intense sapphire-blue hue. If winter hiking and cross-country skiing aren't your thing, wait until early July to visit, when the roads have been plowed and the trails cleared. Rim Drive, a 33-mile road that encircles the lake, has picture-perfect views from all sides. For a closer look, follow the mile-long Cleetwood Cove Trail to the shore. Brace yourself before diving in: The water temperature rarely rises above 55 degrees Fahrenheit.
Lake Nakuru, Kenya
The water is blue enough, and the backdrop—grasslands and rocky hillsides—has the makings of a nice photo, but neither is what sets this lake in central Kenya apart. The real draw here is the mass of pink on Nakuru's edges. Flamingos are one of the few species that can withstand the lake's hostile conditions—the water has so much sodium carbonate that it burns nearly everything that touches it —and they flock to the lake en masse. There can be as many as a million birds feeding on algae in the shallows at one time, wading side by side.
