Garnwerd is a small wierde village (a dwelling mound) situated along the Reitdiep in the province of Groningen.

This access point on the Reitdiep sits at a stretch of the waterway where the river transitions from a straightened, deepened channel — engineered over the centuries to keep the route navigable — into a more naturally meandering course through the open Groningen countryside further north.

The Reitdiep itself follows the ancient bed of the Hunze, one of the region's oldest waterways and historically a vital lifeline connecting Groningen to the sea.

The access point at Garnwerd offers paddlers and boaters a convenient place to join or leave this historic waterway amid the characteristic flat landscape of the northern Netherlands.
