Phi Kappa Campground offers 21 first-come, first-served sites in a wooded setting within Salmon-Challis National Forest, accessible via 23 miles of Trail Creek Road from Mackay, Challis, or Sun Valley/Ketchum.

The campground features vault toilets and picnic tables at each site but lacks potable water, so visitors must bring their own drinking water; it operates seasonally from late May through September depending on road conditions.

The location serves as a base for fishing in nearby streams, scenic driving, OHV riding, and wildlife viewing, with nightly fees of $10 (50% discount for Senior and Access Pass holders).
