 Between the 1930s and the 1950s there was also an "Auto Tourist Camp" where large numbers of tourists tented or stayed in small cabins. A park historian states that in those years "the camp was intended to appeal to the many tourists who were traveling the country in their new automobiles". At one time there were several grist mills located on Minnehaha Creek. The remains of a stone and earth dam of a mill, built in the lower glen in 1853 or 1854, is still visible beside the creek.
