The closest North Sea dog beach to Leiden, 10 km west by Connexxion bus 30. Katwijk has dedicated off-leash dog zones at the northern end (toward Noordwijk) and the southern end (toward Wassenaar) all year round, and the entire beach is open to off-leash dogs outside the summer restriction window (verify the current municipal ordinance, broadly 10:00-19:00 in June-August in the central swimming zone, free elsewhere). Old fishing-village atmosphere, beach pavilions, and the iconic 1605 Andreaskerk church on the dunes behind.
๐ก From Leiden Centraal take Connexxion bus 30, 25 min to Katwijk Boulevard; the southern dog zone (toward Wassenaarse Slag) is the wildest stretch with the fewest summer crowds.
