The Royal Gorge Bridge and Park is definitely the way to go for this adventure. Once you pay the admission to get in you can ride all the rides there (excluding the Skycoaster) as many times as you would for free.
There are places to eat, place to view animals, places to pet and ride animals, free shows of all sorts, and of course tons of gift shops. We saw lots of school and church groups while there and no matter how old or how young everyone seemed to be having a good time.
The bridge itself is 1,260 feet long and towers 150 feet high. You can walk across (warning: it's extremely windy in the middle) and see the different areas on the bridge where people have made record bungee and free fall jumps, take the free trolley, or even drive your own car across and have a picnic in the wildlife area on the other side.
While you are there the Incline Train is a must do! he length of the incline is 1,550 feet and is at a 100% grade, 45 degree angle. The rate of descent is at 3mph but it only takes about 5 mintues to reach the bottom. Once at the bottom you can walk out on a platform over the Arkansas River and perhaps get a chance to wave to tourists on the train that rides along the river.
