A lot of players are wondering how they can visit other parks in Planet Zoo, seeing as they will occasionally see other players in their own zoo. So, how do you visit other zoos in Planet Zoo?
The answer is that this is not something that happens actively, but it is instead a passive activity that will randomly happen without you noticing. Whenever you download something from the workshop or interact with another player, you get tied to that player's zoo, and have a small chance to visit that player. This means that this other player will occasionally see your avatar in their own zoo, but you will not notice this happening.
So unfortunately you cannot go around and visit and browse other people's zoos as you wish, so if you want to take a look at their zoo, you will need to go to the Workshop on Steam, or check them out on YouTube or Twitch.
PS. if you ever see another player visiting your own zoo, make sure to greet them in order to get 20 Conservation Credits!
