Nevada, which is known for its deserts, canyons, and luxurious casinos, has an arid and hot climate that gave it a reputation of the driest state in the U.S. Therefore, the best time to visit Nevada is from October to April when temperatures are cooler. It's an excellent time to dip in the hot springs in Boulder City, hike in the Valley of Fire, go mountain biking around Lake Mead, and ride a horse in Red Rock Canyon. From late August to early September dreamers and artists from all over the world gather for the Burning Man Festival in the Black Rock Desert. Summers are extremely hot, so escaping to some more northerly places like Reno and go tubing on the Truckee River might be a good plan.
