We just barely returned from our trip to Yellowstone National Park. I highly recommend it to everyone! We stayed a few nights at different hotel places inside the park. We did so many hikes! We saw thousands of buffalo and all of the most famous attractions. If you want to see elk just lazing about the town then go to Mammoth. I highly recommend doing things like the Grand Prismatic and Ol’ Faithful in the morning before 10:00 because after that the parking lots get very busy. We ate lunch in several different picnic areas and each one had a restroom. Dont forget to see the Grand Canyon of Yellowstone and also the Huge waterfall! Bring your camera and your sunscreen!
