I love this question! It seems weddings are in the air and it's not surprising to me that a lot of people want to tie the knot here in Oregon. I love that this couple is focused on the "simplicity" of the actual wedding but want to be married "somewhere beautiful!" Enjoy this blog and relish in the simple pleasure that no matter where you choose to make your vows, it's the vow that counts. And, if it happens to be made in the middle of an old hazelnut orchard or on a wooded trail filled with old growth foliage and very old trees dripping with moss, nature has a way of protecting those vows and surrounding them in the arms of the very old limbs to hold them dear forever.
I am the AskOR Willamette Valley Ambassador and I am happy to tell you a bit about where I live.
When I read your question, two places popped in to my head that are absolutely the most perfect places to get married in Oregon. The first place can be found in many areas of the Willamette Valley... a hazelnut orchard! We have so many of them here and they are very easy to find. Taking hwy 99W through the valley will afford you not only the best views and most delicious food and wine you will ever find, it will also be like opening a big book with photos of hundreds of places to get married in Oregon. Along with those orchards, you will find vineyard after vineyard, hundreds of acres of grasses and local greens growing in rolling hills throughout. You will also enjoy some forested areas along the way as well with the most gorgeous very large old trees. That brings me to "spot' number two!
The second most absolutely romantic place for a small intimate wedding would be along the "Old Growth Trail" just outside Corvallis. Here is the link: http://www.cof.orst.edu/cf/recreation/trails.php#old-growth You will find many of the trails there suitable for your plans but I have to say that the Old Growth Trail is a magical place. I go there often and it still amazes me each and every time. In fact, I was just in that general area yesterday. I will try and attach a photo of this forest area and the orchard as well.
Enjoy your trip to Oregon and please let me know if I can help you further. Send me a pic of wherever you choose to tie the knot!
