It can take as much, or as little, time as you wish. If you just take a quick look at each tree and keep walking, I would say 10-15 minutes at most. But if you stop to really look at each tree and maybe take photos, it could take an hour or more. It's really up to you. There's no one trying to get you to hurry through it - you go at your own pace. I spent more time during the day because I took more photos of the different ornaments than I did at night when I just took photos of the overall ambiance.
