Jachthaven De Bloemert is a marina situated on the Hondsrug ridge along the shores of the Zuidlaardermeer, near Midlaren on the border of Groningen and Drenthe.

The city of Groningen lies approximately 15 kilometers away, making it a convenient base for boaters arriving from that direction.

The marina offers around 170 permanent berths with individual finger pontoons and shore power connections, plus approximately 20 visitor berths.

A slipway is available for hauling boats out of the water, and facilities include showers, toilets, and a waste station. The harbor is open for boats from April through November.

Set within Waterpark De Bloemert, the marina shares grounds with bungalow accommodations, a pavilion restaurant with a terrace overlooking the Zuidlaardermeer, boat and bicycle rentals, a tennis court, and a miniature golf course.

The Noordlaarderbossen, a forested area ideal for walking and cycling, lies directly across from the park.
