Elk Mountain lies in the Coast Range of Oregon in between Portland and the coast. It's not a very high mountain but the trail to it's summit makes for a strenuous little hike to a view that ranges from Mt. Hood to the Pacific Ocean past Tillamook Bay. You can even see the nearby minimum security work camp from the summit cut out of the forest on a mountain to the south. Part of the surrounding forest also has burn snags from fires in the early part of the 20th century.
The trail is a hike/easy scramble and gains 2000 feet in about 2 miles. There is a register at top to sign if interested too. The really neat thing about this mountain is that you can combine it with a hike across a ridgecrest to Kings Mountain for a loop hike of 12 miles that gains 4100 feet of elevation (I recommend it). Kings Mountain and Elk Mountain form a sort of horseshoe shaped ridge with dramatic cliffs from the top of the ridge to the base of the mountains down near sea level. Plenty of great views abound from this loop hike. Lots of people make the normal hike to either mountain separately but it does not appear too many do the whole loop from what I could tell in both peak's summit registers.
The best views are on the loop hike between the summits. Beware of ticks on these mountains no matter when you hike. I've gotten more than a few on me both in summer and winter here.
