This is one of my favorite camping experiences so far. Sylvan Lake State Park is a few miles into the wilderness south of the town of Eagle, Colorado, featuring a gorgeous lake with mountains all around it. The campground is next to the lake, and my friends and I all found fantastic sites.
There is a path around the lake, and Matt and I walked around it one morning. It was awesome to see the sun coming up and warming the lake.
I spent one of the days kayaking around the lake after my friends headed for home. The water was ice cold, and it was so relaxing to sit in it, warm in the sun.
The wind blew pretty steadily in one direction, so I was able to paddle fiercely against the wind to cross it in one direction, and then gently paddle and drift back to the other side. I did it a few times, and it was great exercise half of the time. The other half was all about enjoying the scenery.
