On hwy 76 as you head toward Shepard of the Hills and SDC is this observation tower. May I also suggest that you stop on 76 at the scenic overlook for a nice view over the town of Branson.
Go karts on not off the beaten path. You can find them easily in many places on hwy 76. I was not sure if this would be a must see activity on same level as some of great shows I saw.
The Toy Museum is on hwy 76. The admission price of $10 made me decide not to go inside. I thought a great many things in Branson cost more than they should have.
Inside the fish hatchery. It is not fanciest place in Branson but the price is right, FREE. The fish hatchery is just below Table Rock Dam.
