I spent 2 nights here, everyone was very friendly, and the staff was helpful. It rained a bit and quite a few people in tents left, but it was quiet, and my dog and I took long walks, very enjoyable.

Visited June 2024. This was our first camping trip and absolutley loved it. The staff had a pleasant attitude and was willing to assist. If this is the experience to expect, then I want to visit this location many more times. Thank you for making our first experience a great one!

The only negative about Lock A is the massive hill right before the gate to the park.

Would be good if there was more than 1 camp host so someone is on duty every day.

Had a great couple nights tent camping on my favorite site, but the second night there blew in late afternoon a wicked windshear that took down my tent and the four next to it on the lake's edge. I watched it from my car, where I had taken refuge from the powerful downpour. It was quite a memory, haha. I ended up clearing the campsite into my car and sleeping in it then taking off early the next day. But all in all it was quiet, peaceful, and a great little trip. I'll be back.

Great place to stay and relax. Plenty of shade combined with wind off of the river makes it comfortable even when temps are high. Park attendant one of the nicest we have every been around at a COE campground.
