Where: Hagerman Valley, south-central Idaho (Hwy 30)
Drive from Star: ~2 hours southeast
Why visit: One of the clearest examples of large-scale aquifer discharge in the West. Ritter Island, Malad Gorge, and multiple spring-fed waterfalls visible from the road. Hagerman Fossil Beds nearby.

🌲 Forests & Prairies
