We have camped in the area quite a few times and find the area very nice. This is NOT a campground but there are 3 just down river for you to choose from. This day use area is clean with activities for kids including a play area and clean bathrooms. There are quite a few picnic tables and a shelter and lots of hiking options. The drawback to this place is swimming in the West River because the Townshend Dam restricts the flow and the "swimming" area is often in bad shape. The silk collected makes swimming less desirable. At times that river gets really shallow and kayaking isn't a lot of fun. There are projects planned and the silt has been dredged but it comes back again the next year. So for day use, I would recommend it and exploring the river bank is great fun for kids of all ages too.
We've gone with picnic lunches and spent the day hiking and relaxing. I great place to spend the day.
