The…read moreupper Mississippi River has 29 lock and dam structures built along it, forming a "stairway of water" that allows barges, towboats, and pleasure boats to travel from St. Louis to St. Paul (or vice versa). These striking structures aid these barges and boats in adjusting to the elevation change on the northern section of the river. I've seen locks on the Thames from when I lived in the UK but never knew that the Mighty Mississippi had locks. I was surprised and had to check this one out. Sadly, it's completely secured with strong fencing and while you can see some of it from the riverside, a tour would be needed for a proper look. And yes, some of the locks do offer tours - Dubuque Iowa, Fulton Illinois, Rock Island Arsenal Illinois and Illinois City Illinois - this isn't one of them. You won't find locks and dams on lower sections of Mississippi River. Why? The Missouri, Illinois, Arkansas, Ohio, and other rivers flow into the Mississippi, making the river naturally wider and deeper downstream. [Review 19732 overall - 209 in Missouri - 704 of 2023.]

When you go for this tour Juan loves to share the knowledge and information about the family and the details. I don't want to give too much away because you really need to visit! But Tiffany stained glass throughout the house, leather wallpaper, and so much more. This mansion was made before its time and is a masterpiece! The only issues we stumbled on were locating the parking and then finding a place to park.

They are absolutely capitalizing on his upbringing here with a museum, statues, and all sorts of structures named after the man who some would call the greatest American writer. Tucked at the bottom of Cardiff Hill at the intersection of North and Main Street, this statue of two of Twain's most famous characters. Tom Sawyer and Huckleberry Finn's adventures took place in the fictional town of Saint Petersburg but it was very definitely Hannibal. The statues are by artist Frederick C. Hibbard and worth a stop as you're visiting the city. [Review 19717 overall - 195 in Missouri - 689 of 2023.]

Our tour guide was Avery and he was fantastic! From the middle that we stepped out to take a picture in front of the cave until we exited through the gift shop. It was a great experience. We walked through places in the cave that were noted in the adventures of Tom Sawyer, and through the cave history, including the thousands of signatures in the cave. We also participated in 15 through a pay dirt bag. This space is grade for all ages, and they have ample souvenirs. In the gift shop. We even visited the winery across the street.

When are you going to see a lighthouse in the middle of the country? This little lighthouse was…read morebuilt in 1934 to honor Mark Twain on the 100th anniversary of his birth. The picturesque lighthouse is non-functional and overlooks the Mississippi River. There is a plaque that describes the history of the lighthouse, which was dedicated in 1935 by Franklin Roosevelt. In 1960, the lighthouse was destroyed in a windstorm and rebuilt in 1963. The current building was dedicated by John Kennedy in 1963 and later renovated in 1994. You can see the lighthouse house from downtown Hannibal and climb the steep stairs to view up close. We drove up the windy road to the base where there is free parking for about a dozen cars. After ascending a short flight of steps, we were rewarded with views of the Mississippi River, downtown Hannibal and peeks of the Mark Twain Memorial Bridge. The lighthouse is not open for tours, it's just an outside visit. There is no charge to see the building. There are no amenities at the site except for a bench. The lighthouse is worth a short visit.
