Red Rock is beautiful! It's definitely a must-visit place (after Lake Mead) if you're visiting Vegas. The colors of the rock are so vibrant and at times you'll literally feel like you're on location in a movie! It's great for all fitness levels because you can pick trails based on their ease/difficulty and it's also a great place to explore with your dog. If you have out of town guests I definitely recommend taking them when the weather is nice. Entry was $10 a vehicle. It was a 25 min drive for me to reach there from South Vegas (Eastern and 215). Go out and be active while also having fun and appreciating God's masterpiece! You will love it!
