Reservations for sight seeing tours??

Here's a nice write-up of the ferry trip. A highlight for us was going through the Wrangell Narrows (see Day 5-6). It is truly, very narrow and shallow and cruise ships cannot use this passage. The waters have many red and green navigational lights. It looked like Christmas. We came to a tiny village which was up on the hill and the ferry captain slowed almost to a stop. The townsfolk ran down the hill to greet us, waving and laughing. They don't see many ferries come through so this was a big thing for them. We were so close to land that we could carry on conversations with them. It was truly awesome!
