Nice place with a beautiful shopping centre called Geesterduin. The Hollands Duin reserve is lovely and you can go on daytrips to Egmond aan zee.
The place Castricum is not really special. There are no cultural sights but the environment around Castricum is worth visiting. We made tremedous bike tours and it is also nice to linger here in bad weather.
Going out here is nice, there is a large parking place at the beach. Blinckers is very trendy and nice, it is a pity that there is no boulevard.
