The Glass Bottom Boat Tour is the newest cruise offered on Lake Superior. Unfortunately, on our visit, recent storms had made the lake cloudy, and we were not able to see much underwater except a few ship remnants.
The Superior Princess is a two-level vessel that allows for enclosed or open-air seating, with two glass viewing platforms on the lower level. The boat holds approximately 150 people. Once onboard, we got a basic safety introduction, an Apostle Islands 101 primer and an hour of silence as we made our way toward Stockton Island. Then we had our first chance to see a shipwreck along Julian Bay. Noquebay was a barge boat that caught fire and sank in shallow waters. We caught a glimpse of the keel and several boards mostly covered by sand. The tour boat made multiple passes over the area so passengers could take turns looking out the viewing platforms.
We visited three more shipwreck sites, one of which was a tugboat that caught fire while docked and was pushed into the water so the blaze didn't spread to the mainland. We also passed an abandoned ship along the shoreline.
After two hours, we were ready to head back to the mainland. All in all, we were disappointed. There weren't enough shipwrecks to merit a themed cruise, and the narration was not as informative as what we'd experienced on a regular Apostle Islands boat tour. We'd urge visitors to bypass this and opt for the regular cruise.
