At the moment, forests and parks are open in general, but only till 8:00 PM, then the pandemic curfew begins. Apart from that there are several other rules, f.e. you should have a negative antigen Covid test on you and so on. It is probable that if things get better, in May several of these restrictions might be lifted, even outside seating of restaurants might be allowed. But no one knows for sure now.
