1. Check out Mammoth Hot Springs
These amazing geothermal waterfalls and rock formations make some stunning photographs with the bright oranges and sulpurous whites. I have yet to see anything like this.
2. Take Instagram photos of Grand Prismatic Spring
It's hot and smells like rotten eggs but the springs in Yellowstone again, make some beautiful photographs. The bright colours are due to thermophilic bacteria which form the rich reds, yellows, blues and greens in these pools.
3. Swim in the Boiling River
I went on my birthday and it felt like the fountain of youth. It's a natural river that is also fed by a hot spring river making it lovely spot to sit for hours if you can find a spot that has a good mix of both hot and cold waters.
4. Swoon in the West Yellowstone Discovery Centre
I loved the bird talk where they brought out this tiny owl called Arcadia who was the size of a cup. Cutest thing ever! It was a good place to check out bears, wolves and bald eagles up close as they are pretty hard to spot in the wild.
5. Pretend You're David Attenborough in Hayden/Lamar Valley
Thousands of bison and their babies (we went mid July) is quite the sight. We were lucky enough to have them cross the river and get really close to us. We also spotted heaps of other animals like a grizzly bear, pronghorn deer, osprey and normal deer. Amazing when you can see these animals in their natural habitat.
