Bohemian Paradise is an ideal place for your free time activities! The biggest area for this type of activities is Malá Skála. You can find there popular boat, scooter or in-line skates rental or a giant rope centre. Your task is to take a picture of you doing some of the activity or just visiting the pantheon.
(Personal tip: Before you leave village Malá Skála we recommend you to visit castle Pantheon (Vranov) which is right above the river and restaurant "Boučkův statek" with delicious Czech cuisine. After landing you can visit Dlasek Farmhouse (example of folk architecture) restaurant "Abelův mlýn" in Dolánky - it is one of the best restaurants in the Czech Republic according to Maurer choice. The places are easily accessible by train.)
