There were a lot of places we visited that had Lord of the Rings / Hobbit connections, but Hobbiton was the only place we visited specifically because of Peter Jackson.
We went in 2018 and wanted to go again, the experience was different. The grounds have matured more. The hobbit holes are surrounded by landscaping. This has developed over the years. We visited earlier in the summer this time, so different plants were in flower.
There are now two Hobbit holes. You only can go into one as part of the tour. It took 9 months to build the holes by a team who had worked on the films. They are magnificent, the attention to detail is beyond belief - The noticeboard contains fliers and invites for groups and events in Hobbiton.
