Every year, there is an Open Farm Sunday. Around 350 UK farms will be free for visitors to explore and enjoy. Activities on offer may include farm walks, nature exploration, lake observation, talks and exhibitions, and mini markets. Open Farm Sunday was set up in 2006 and more than two million people have enjoyed the experience since then.
