Pampushaven is a harbour situated on the IJmeer, the lake that stretches between the polder De Nes, Hollandse Brug, and the mouth of the IJ near IJburg, straddling the provinces of North Holland and Flevoland.

Its position gives it direct water access to the IJmeer by boat while also connecting to regional land infrastructure, making it a practical staging point for activities on the lake.

The harbour has been identified as well suited for logistical operations across the IJmeer, with enough space to accommodate dredging barges and to store materials.

Its combination of waterfront access and regional connectivity makes Pampushaven a notable access point for those approaching the IJmeer from this side of the lake.
