I had one extra day as part of a visit to Seattle, Washington in July 2021 and I decided to rent a car to visit Mount Rainier National Park. Only having one day, I wanted to get the most bang for my buck so I chose to hike the Skyline Trail. If you have enough time and are in decent enough shape, I can't recommend this hike enough.
The Skyline Trail hike took me about 4 hours to complete round trip and the views throughout were breathtaking. My hike ended around sunset which created some beautiful moments and thin crowds. I even saw a pair of massive mountain goats. Get out to Mount Rainier when you can!
Here are my favorite photos from Mount Rainier National Park. Enjoy!
