We just had our wedding here.

Location: The ceremony place is extremely beautiful. You are next to the water, the background is the mountain, and you are surrounded by the trees. You have three choices for your ceremony spot and three options for the reception, both indoor and outdoor. Both have their own beauty. It is also very peaceful and not crowded even though it is a park.
The ceremony site is on a small island that is walkable (next to) from a parking lot.

Price: We have looked at various venues, both in Portland and Seattle. I think it has the best price with the views you get. Contact them if you do not want to purchase the entire wedding package and they are very flexible. They do not have a required vendor list which makes your wedding even more affordable. They can provide tables, chairs, linens, bluetooth sound system (in door/outdoor), arch, setup help. You could rent a bridal suite to get ready.

Management: The manager Jeanetta is literally one of the kindest person I have ever met. I think she alone deserves a 10 star rating. She truly cared and went above and beyond to help with our wedding. She was flexible, thoughtful and always willing to work with you! Other staffs at the office were also extremely nice.

Port of Cascade Locks Marine Park was a wonderful site for our wedding! We had the ceremony on the island and then had the reception indoors at the Pavilion. Everyone had a great time and the views of the river and the Columbia Gorge could not be beat! It's the perfect location if you're looking to show off the beauty of the Pacific Northwest!
