At 300 acres, Sloterpark is Amsterdam’s largest park. Located in Amsterdam’s western neighborhoods (Nieuw-West), it was developed in the 1950s using excavated soil. There are lovely nature trails through the park, and separate pedestrian and biking trails in spots. A highlight is the loop around the lake, Sloterpas, which is about 4 miles — including the slightly more rugged Het Ruige Riet (Rough Reeds) nature reserve in the northwest corner of the park. The park has an Olympic size swimming pool, an outdoor pool, gym facilities, and sailing and watersports clubs. For a longer run, Rembrandt park is 1km to the east.
