What Guests Are Saying
Lock A campground is well-maintained and offers beautiful river views, spacious sites, and friendly hosts, making it an enjoyable place for camping. Visitors appreciated the cleanliness of the facilities, good connectivity, and access to water activities like kayaking. While the narrow and steep road to the campground and some dated bathroom facilities were mentioned as drawbacks, overall experiences were positive, with many guests eager to return.

We had an amazing family trip here. The keepers are so kind! The showers are cleaned daily and there's a beach down the road. Plenty of play areas. My girls loved seeing the barges come down the river. We will be back!

Stunningly beautiful and relaxing. Many sites are waterfront on the river. Adjacent to exceptional walking/hiking paths.

We love staying at Lock 4. It is fun being right on the river and watching the boats and barges. We also enjoyed biking on the trail and walking down to the dam. It is a very relaxing, quite campground. The sunsets are also great!
