Locktender House 3  (Max capacity 40)

The Lock Tender house is one of three historic locktender homes within the Marine Park. Constructed in 1905, this house was completely restored in 2010 to provide a unique rental space for private parties and meetings. Guests enjoy the historic photos on the walls inside, almost as much as the views of forested Gorge cliffs and the Columbia River outside.

The Lock Tender's meeting room on the main floor is ADA accessible with a ramped approach from the south side of the building. Tables and chairs are included, with seating up to 40 people. A basic kitchen with dishes, a 3-compartment sink, oven, stovetop, small dishwasher, and microwave is available for guests to use. Men and women’s restrooms are attached to the meeting room on the main floor. Parking is shared with the nearby Thunder Island Brewing Company, and occasionally the campground

Thunder Island  (max capacity 200)

Rent your own island in the Columbia River for your wedding ceremony or next event!

Thunder Island is a small island that was carved out of the mainland in 1890 to build the Cascade Locks and Canal. The historic locks and canal provided safe passage around the rapids for ships traveling up and down the Columbia River. Today the island is used by visitors for walking, picnicking, photography, and special events. The island boasts views of the mountain peaks across the river, forested Gorge cliffs, and the famous Bridge of the Gods just down river. Visitors enjoy watching barges, fishermen, and sail boats in action.

Thunder Island is a short walk from the mainland, accessible by a footbridge. The island offers maintained lawns with trees, scattered picnic tables, and a wooden platform overlooking the water for special ceremonies. A small shed contains 200 white resin chairs included in the wedding platform rental. One power outlet is located near the platform. Nearby interpretive information boards tell of the geology of the Gorge and history of the locks.
