This is a large set of coastal meadows, ancient rivers and areas of reeds. It is found at a location where the Daugava River used to flow – between Vecmīlgrāvis and Vecāķi. There are inland dune meadows here, complete with the very rare silver grass. Vecdaugava is an important location for nesting birds and several uncommon plant species. On the southern end of the Vecdaugava peninsula, at a place called Skanstnieki, one can find remnants of medieval Swedish fortifications. The Vecdaugava Regional Research and Fishing Museum is here, as well.
