Colorado is home to some of the greatest hikes in the world. With sweeping views of mountain ranges and forests, it offers trekkers the opportunity to see spectacular, one-of-a-kind views. But that doesn’t mean they come without risk! It’s also home to some of the most treacherous hikes in the world, including Longs Peak. This trek reaches 14,259 feet in the air, with a 14.5-mile climb and huge, precipitous cliff that makes it insanely dangerous. Trekkers need to be very careful on this deadly mountain and should not attempt it if they’re an inexperienced hiker (Only In Your State).
