Bonnema Watersport is a boat-rental business located on the Oud Loosdrechtsedijk in Loosdrecht, situated at the edge of the Eerste Plas on the Loosdrechtse Plassen.

It serves as one of the two designated starting points for the marked canoe route through the Vuntus, a swamp forest managed by Natuurmonumenten that is open to non-motorized vessels only. The route is signposted with numbered blue poles.

Paddlers beginning here must cross open water to reach the Vuntus, making calm conditions advisable before setting out.

The business also offers motorboat hire, with the passage toward the Eerste Plas found just past the Bonnema beach and rental facility, beneath a bridge.
