According to Coastal Indian legend, Neah-Kah-Nie Mountain is seen as a sleeping warrior, waiting to be awakened. They thought it was a viewpoint fit for the gods, so they named it Ne (place of) Ekahni (supreme deity)(per Sullivan's guide). I certainly concur about the view from the summit, which on a sunny day is an awesome sight, especially of the Nehalem River valley to the south. I am glad to note that the warrior remained safely asleep the 3 times I have been there.
I recommend this hike highly if you are in the Cannon Beach area and have a few spare hours and want to get in a nice short workout, or if you just want to enjoy some great views of a beautiful area.
Note: I have seen this mountain listed at both 1697 and 1631 feet. Every time I have been up there, the summit comes in at between 1685 and 1700 feet on my GPS, so I have used 1697 as the correct height.
The south trailhead is about a mile and a half south of the west one, between mileposts 41 and 42, not quite 2 miles north of Manzinita. There is a brown hiking sign pointing to the road you need to take, which will be a left turn if you are coming from Cannon Beach. It is about 4 tenths of a mile to the trailhead, which has room for maybe 5-7 cars, although you could park farther down if all the spots were taken.
