Hike Through Time

Manhattan Project Rangers host a free guided, 3.6-mile (5.8 km) round-trip hike up Candy Mountain twice a year. This hike will take you through time starting with the Native peoples who have lived here since time immemorial. As we make our way up Candy Mountain, we will delve into the stories of early explorers and settlers. Approaching the peak, we will touch on the impact of the Manhattan Project on the area and its inhabitants. After reaching the peak, we will learn about the lasting legacies of these stories.
As information is available, details will be posted to our event calendar.
