Dege Peak has become my favorite WA hike yet! Outstanding views of Mt. Rainier (and occasional great views of Mt. Adams and Mt. Baker, if the weather is clear enough), wildflowers of all colors at many spots on the trail, and just the right length. It took us about 2 hours and 15 minutes to hike, which was perfect for a shorter day hike. It's exposed almost the entire way up, so you get panoramic views basically the whole time. Also, despite the Sunrise Visitor Center being quite crowded, we had the trail to ourselves for much of the hike.
There were a couple of small issues - they didn't detract from our time at all, but other hikers may want to know about these. First, there was a short wait to get into the sunrise area. It was advertised as a long wait, but only took about 20 minutes. Second, there were a couple of spots with snow on the trail. We were able to pass most of these easily, but one had enough snow to make crossing a little sketchy. Otherwise, the trail is really well-maintained and smooth. Last, there were a lot of bugs, especially at the top. We didn't really have a problem with the bugs, except after we had been at the top for a while. Most of the bugs were butterflies, which was really neat.
Since Dege Peak is at a higher elevation than many day hikes in the cascades (with the highest point at 7006'), it was good that we picked a shorter hike like this. I noticed that I got out of breath more quickly and more often than usual.
Anyway, it's a really beautiful hike, and appropriate for many ages and abilities. We will definitely go back!
