Cascade Creek Campsite is a sweet spot for large campervans who are looking to be close to the top day hikes in Fiordland and Milford Sound. With 120 non-powered/tent sites, this standard campsite has lots of places to park. It's 15 NZD per adult to camp here and you technically need to pre-book. However, we just rolled in in the evening and it wasn't an issue. Just make sure to bring cash to put in the box on the campground.
