Sit on the grass and enjoy the lovely scenery at Belvoir Park. After a long day exploring the sights, it's the ideal place to take a breather.
You'll be spoiled for sightseeing choice when in Zürich Center. Belvoir Park is an ideal place to kick off here, but there are many other worthwhile spots to discover. Bahnhofstrasse, Zoo Zurich, and Swiss National Museum are not far from the recreation and green space and will round out your day nicely.
