Beautiful wooded campground with a water ford crossing and tunnel! There is a way to avoid the tunnel while pulling a travel trailer or 5th wheel. Wonderful hosts.
The entire area of Madison County is very tranquil, historic and beautiful! the campgrounds are easily accessible to get in and out of town. the hookups are not as available. so I suggest getting there early. great place to get out of town and fish and explore.
Pammel Park is awesome. It is actually a State Park that is managed by the local County Conservation Board. Pammel Park has amazing trails with varied terrain and nice forests.
The campgrounds are clean with options for tenters and RVs. There are even Yurt Cabins that can be rented. Pammel Park has a great water trail for Kayakers with several launch points.
The only caution I would have is pay attention while you are hiking, there are rattlesnakes in the park. Overall I highly recommend Pammel Park. It is about a 30 minute drive from Des Moines and about 5 minutes from Winterset.
I would consider Pammel Park a secret gem even for native Iowans. Checkout Pammel Park and spend some time in the historical town of Winterset.
