Cycling to the Danubiana is pleasant and not demanding. The bike/skate path is located on the embankment which can be reached by crossing any of the Bratislava bridges. You will know that you’re getting close when you reach the Obrátka refreshment stand. Turn left just after the stand and follow that road to the Danubiana. You can take a break at any of the refreshment stands along the way or at the Rusovské jazero (lake) on your right. The trip shouldn’t take more than 90 minutes.
Cyclists who don’t have a lock can borrow one (also free of charge) at the museum reception desk.
