Isbladskärret is a part of the Royal National City Park, located on the north-eastern part of the island Djurgården. It is a wetland home to a vast number of different birds, such as the northern goshawk, heron, common coot, great crested grebe, European green woodpecker, great spotted woodpecker and house martins. It is a really great place to watch birds close to the city centre, if you are into that sort of thing, but the tranquillity of the spot makes it a lovely place to just recharge your mental batteries and stop for a snack (which you’ll have brought yourself as there are no shops in the immediate vicinity) while strolling along the beautiful Djurgårdsbrunnskanalen.
You get there by taking bus 69 from the Central station in the direction of Blockhusudden. Get off at Edelstams väg (takes about 16 minutes) and walk towards the canal.
