If want to top up your tan, you might want to head out to Sandstrand, located 2 mi (3.2 km) from central Isernhagen. Enjoy the sunset by the shore at Mini-Golf.
If you like spending time outside, why not spend the afternoon at Silbersee, a park located 4.2 mi (6.7 km) from the center of Hannover. Want to stretch your legs some more? Head to Eilenriede and Herrenhausen Gardens, both nearby.
