Is it possible to safely park a bicycle near the entrance of the Ouwehands Dierenpark?

I plan to visit Ouwehands Dierenpark with a friend, and to move more quickly around we plan to use bicycles and carry them with us on trains.

Is it possible to safely park a bicycle near the entrance of the park? Or would it be more sensible to leave them elsewhere?

I tried looking with Google Maps and Street View, but I could not really locate a spot dedicated for them (as opposed to the large car parking lot east of the entrance).
