Wedged between two mountains, the Knudsen Gap was a scary place indeed in the 1800s. This trip through the narrow passage was a dangerous one as robbers could easily ambush a traveler. The construction of the main island road decreased crime in the gap. Today you are only likely to be ambushed by beauty. You can see the pass on Highway 50 from Lawa'i to Lihu'e between mile markers 8 and 9.
