Nice location and amenities
Sites are spread apart nicely. Each one has a picnic table and fire ring. Grassy spots that are fairly level and mowed. Came with firewood and a little kindling too. Trash can with lid provided (didn't find a suitable tree to hang our food, so we stashed it in the can overnight).
The well-maintained porta-potties near the maim building make this a great option for those who aren't into fully roughing it. There's also wash-water available (no drinking water though). Thought the price was high at first, but would definitely take my family here given the amenities.
From the Towpath Trail, there's a connection at Canal St, which is a little easier than using the actual trail-head a little north of there.
