Forestry Commission's Haldon Forest Park launched its page with news updates, events information and photos.
Rangers will post regular blogs keeping people in the loop with developments such as work on the new cycle trail and news about the new café opening at Easter.
People can become fans and upload their own photos or videos and post reviews of the park on the page, said park ranger Gemma Ingall.
"It is important we get information out to people about what there is to do at the park, and the health and well-being benefits of spending time in the forest.
"With Facebook becoming ever more popular we see our new page as a great way to do this and also to engage with a wider audience.
"It is also going to be a great tool for myself and the rest of the Haldon rangers to keep people informed of what is going on.
"We will be posting blogs regularly. The page is interactive so people can share their own photos, experiences and feedback."
