Today we got to explore one of the lushest, wettest, most spectacularly beautiful parts of the Tongass National Forest, Cascade Creek. We broke into three groups and hiked to different points up the creek. The easiest was only about 1/4 mile up to a gorgeous waterfall that produced perpetual rainbows and the furthest hike was about 4-5 miles round trip. There was a rope to climb next to some slippery wet stairs that were carved into stone at one point. After lunch we took Zodiac tours of Thomas Bay and then almost everyone on the ship did the polar plunge.
