Donmouth Local Nature Reserve (LNR) is a beach site found in Old Aberdeen.
Where the River Don meets the sea, beside the A92 a few km north of the city centre, the estuary in the Donmouth LNR gives excellent scope for seeing waders, terns and seabirds. Seals use the sand spit near the mouth of the river.
Facilities include car parking, cycle racks, and toilets. Ranger led activities are available during the summer months.
