Grab your camera and take photos of the vessels moored in the harbor at Piet Hein Marina. Colorful sailboats together with the rippling water can make for some lovely snaps.
When you've spent a bit of time at this Loosdrecht yacht and boat harbor, why not make your way to Loosdrecht Lakes, Vinkeveense Plassen, and Hilversumsche Golf Club? They're not very far from Piet Hein Marina and also popular with many travelers.
