Planning a weekend trip

It's Anish's birthday this Saturday. Am busy thinking of new ways to spend the day as he is not very keen on a birthday party. Last year we did temple, cake cutting, donation to an orphanage and Wonderla. This year there will be temple, cake cutting, donation but the place of picnic is undecided...
Anyone can help me? Please bear in mind, I cannot do rock climbing right now. My bump doesn't permit me...
