Twelve holes. Not nine, not eighteen. The Frog does its own thing in the North Shore suburbs and expects you to keep up. Semi-private status means tee times exist if you know where to look. A 70 walkability score suggests the terrain cooperates more than it fights you. Long Grove sits far enough from Chicago to feel like an escape without the drive becoming the main event. The loop format keeps things moving. Show up ready to walk something different.
