For people not so well acquainted with London it may come as a surprise that on the outskirts of such a metropolis, just a short train journey from the city, there is a large natural open space with wild deer wandering around freely. And there are a lot of them!
Richmond Park is a national nature reserve and deer park with 630 Red and Fallow deer roaming freely since the mid-16th century. It is one of the largest parks of London, situated in zone 4. It is said Richmond park has changed little over the centuries, despite being surrounded by human habitation. Its landscapes have been a location for several films and TV series.
For obvious reasons it is not allowed to feed the deer, but you can come relatively close to them(up to 50 meters in distance) without scaring them off.
