Kayak Photography
What are good non-beach places in the US to honeymoon in mid-October? We love hiking/kayaking/photography.?
Oregon is magnificent in the fall! Take a look at the Columbia Gorge, stay near Multnomah Falls, and kayak on the rivers that feed into the Columbia.
Or head closer to the Pacific; the southern half of the Oregon coast has great rivers (the Rogue and the Deschutes are famous for kayaking and rafting). Port Orford has a magnificent seacoast, and Bandon looks like a tiny New England fishing village, with a charming Old Town/Fisherman's Wharf area.
In October 2005 I helped put on a three-day car rally from Portland to Port Orford and back, and by the end of the day Sunday I was telling friends that I had finally seen enough fall colors. 
Not that I was tired of them, but we put in 664 miles from Friday to Sunday, with only about 50 on interstate highways (and frankly, even I-5 in the middle of the state is incredibly scenic).
It's going to seem like an odd recommendation... but take a look at the Oregon Department of Transportation Web site, in the Sources field, to get a sense of where things are. The site has Web cameras at crucial highway spots throughout the state, and while the ones in downtown Portland could be in almost any crowded modern city, you can at least see where some of these places are in relation to the primary "points of entry" for tourists (Portland in the north, Medford/Ashland in the south).
If you're early enough in October you might also still be in time to see a play at the Oregon Shakespeare Festival in Ashland, which is a charming city in the Siskiyous. Ashland is gorgeous in the fall, and you have your choice of modern luxury accommodations or restored 19th-century hotels like the Columbia (our favorite, close to everything and charming, but since it's a honeymoon, be sure to get a room with a bath, it really IS a 19th-century hotel and not all rooms have them!)
You could spend a day or so in Ashland, then kayak down the Rogue River, or try the Coquille River, and end up in Bandon.
I wish I had more pictures of the Port Orford Rally, but there are a few on line at the Oregon Rally Group's home page, also in the Sources field. Nothing though captures the feeling of coming out of a dark forest road with trees intertwining overhead, leaves green and golden all around you, and then bursting out into a little coastal valley with farmland stretching out to the dark fir-covered hills on the far side, the mist just beginning to rise from the green fields and curl among the orange maples and yellow-brown oaks. If I were taking a second honeymoon, that's where (and when) I'd go...
