Julianadorp aan Zee
Julianadorp aan Zee is a coastal town in the head of Noord-Holland, located at the foot of the dunes. Behind the dunes, about 400 meters away, is the beautiful wide sandy beach, for a nice day at the beach, a nice walk at the beach or to get a breath of fresh air. At the beach entrance is also a beach pavilion (Paal 6), which is open all year round. The beach entrance has the blue flag and there is a beach post of the rescue brigade. Julianadorp aan Zee is a good base for walking and cycling trips through the vast dunes and polders and in spring along the flowering flower bulb fields.
