The English Garden can seem overwhelming when you enter it. It is Europe's largest park, and the Isar, a fairly large river, mends through it. But if you take a tour first and visit again later, it is much easier to get a grasp of the second time.
There is a lot of wildlife to be seen along the river. Parts of the river are designated for nude sunbathing, and Munich residents take full advantage of it on hot days! There are also ducks, swans, and a plethora of other birds.
There are two great things you must do in the English Garden. The first is have a beer or apple cider at the beer garden. It is located next to the Chinese Tower. They have food as well, but the beer and cider are some of the best you will have. Sit as close to the Tower as possible, and you might catch some traditional German music.
The second sight to catch is the wave area of the river. The Isar naturally has a huge wave pool, and in summer, there are many surfers that will frequent the pool. It's quite interesting.
