Maasydänjärvi and Ahvenlampi 4570

Pond waters in the municipality of Sievi in Northern Ostrobothnia that offer great opportunities for fly fishing enthusiasts and other recreational anglers. Maasydänjärvi is a full-service angling destination for many kinds of fishing and it is located next to a camping area. Fishing at Ahvenlampi is a more rugged experience in the quiet wilderness where the exhilaration of fly fishing can truly be felt. Catch-sized rainbow trout is planted into these ponds in the summer and anglers might also run into a whitefish or two.
