Probably the most beautiful place I’ve ever been to. Absolutely changed me. Since my visit I still find it surreal. It’s a place everyone should experience. But, you should also respect it and the animals. Pictures are great! Just take them from afar. This is not a zoo. If you are on limited time, you can do that entire loop around the park in a day. The downfall is you can’t stay in one spot for too long. The visitor center is a must see. Take your time there for sure. And Old Faithful was a sight to see!
