You'll probably want to stock up on snacks and water here, since there's no services available for the next 45 miles, and you'll be tackling one of the tougher coast range passes in northern Oregon. Main Street becomes Meadow Lake Road as you go west out of town. You get a few flat miles before the real fun begins -- from ~350 feet of elevation at milepoint 70, all the way up to just under 2,000 feet by mile 79.
At about that point, you go by McGuire Reservior (it'll look damn tempting for a dip on a hot summer day, but the big tall chainlink fence around it tells you otherwise) and start to follow Nestucca River Road for most of the way until you reach Highway 101. There's a few campgrounds along the way (may or may not have toilets or potable water), and one three-mile stretch of gravel around mile 90 that's, in my experience, fairly hard-packed but also pothole-y.
You rejoin civilization of sorts in the lovely town of Beaver, OR. A Shell station/market is probably your best bet for any supplies you might need for the last twenty miles of the day (there's a few other businesses, but the Shell is the only one I've seen be consistently open for business).
Three-ish miles north on 101, then left onto Sandlake Road... which means, of course, a climb over Cape Lookout. Not too hard, but it's enough to push your day's total elevation gain over 10K so it might not be too enjoyable. From there, a descent down to Netarts Bay, then six flat waterfront miles into the endpoint in Netarts, OR.
