What KSMN publishes

Instrument approaches at KSMN

Lemhi County has 3 published instrument approaches of 2 types (RNAV (GPS) and VOR). 2 of them offer vertical guidance; RNAV (GPS) gives the lowest minimums. 2 are circling only — bringing you to the airport rather than a runway, to circle for whichever runway the wind favors at circling minimums.

No published approach to runway 35: landing on that end in instrument conditions means a circling approach or a visual after breaking out.
