If you only have one day to hike in Mount Rainier, make sure it's the Skyline Trail. It is arduous, but it's definitely the best way to see the mountain in all its glory. If you have a little more time to spend in Mount Rainier National Park and are looking for another perspective, the Pinnacle Peak Trail is an excellent hike with great views of Mount Rainier.
The Pinnacle Peak Trail is about 3.5 miles round trip and less than 1,000 feet of elevation gain. It was a bit of a strenuous climb for sure but definitely worth it for the views of Mount Rainier. The Pinnacle Peak Trail starts at a road-side parking lot at Mirror Lake, which is another favorite sight in Mount Rainier National Park in its own right. I mean, look at that reflection!
The Pinnacle Peak Trail offers amazing views of Mount Rainier, and I was a little astounded and very excited that I hiked above cloud-level.
The hike also featured plenty of beautiful wildflowers. July is an excellent time to be in Mount Rainier National Park if you are a fan of wildflowers, and I really enjoyed the many colors dotting the meadows.
