Tourists who travel to the state of California make it a point to visit one of the world’s most popular national parks, the Yosemite. And here in this beautiful park is where you’ll find one of the oldest lakes in the western part of the world—the Mono Lake. Experts say that it’s at least 760,000 years old. One of the many things that would captivate you is how the lake provides a striking reflection of the Sierra Nevada. And let’s not forget that its crystal waters are surrounded by majestic volcanoes and awesome scenery. If you’re going to Yosemite, make sure you include Mono Lake in your itinerary.
