De Holle Poarte is a beachside campground located directly on the IJsselmeer at Makkum, in the Frisian province of the Netherlands.

The site features two large sandy beaches with shallow, calm water well suited to young children and beginner water sports enthusiasts.

Consistent onshore winds make it a popular windsurfing and kitesurfing destination, and surfing equipment rental and lessons are available on site.

Camping pitches range from basic to comfort-level, each roughly 100 m², and are situated between 50 and 250 metres from the beach. The campground is surrounded by four nature reserves, including the Zuidwaard and Noordwaard, and sits next to Marina Makkum.

On-site diversions include a petting zoo with alpacas and goats, outdoor play equipment, and a children's lounge with digital games. The site serves as a practical base for exploring the broader Frisian waterways and landscape.
