Our first full day at Peninsula State Park was fairly low-key.  After breakfast we explored a bit, trying to get our bearings.  The first stop was Nicolet Beach, where the park's swimming area, concessions, camp store, and so forth are located.  From there we took an easy hiking trail across to the lighthouse which sits at the north end of Tennison Bay, then walked back to our site.  We enjoyed relaxing in the afternoon---still nice weather with sunshine and temps around 70 degrees.

This is really a beautiful spot: lots of birch trees and wildflowers.  The water is very clear and looks so blue from a distance.  The only negative is LOTS of poison ivy!
