This is a great place for both locals and out-of-town visitors. There are some fee areas inside but you can choose to just stay in the free section and have a great time. The museum atmosphere is serene. Adults can find enjoyment touring the exhibits but there are also many things that appeal to children. Best of all, since its free you don't need to stay a long time just to get your money's worth. The exhibits are very professional throughout the main floor. The staff has worksheets of "can you spot these items" for children. In certain areas there is dress-up clothing that kids can put on that makes for fun photos. Upstairs is a huge 3D map showing Northern Colorado's water management. The map includes all the high peaks and lakes in RMNP and mountain lovers will find it fascinating to study.
