Forteiland Pampus
A UNESCO World Heritage sea fort on a man-made island reachable only by ferry from Muiden, with 400 years of Dutch naval history to explore. Walk through maze-like underground chambers, cannon cupolas, and multimedia exhibits bringing military stories to life, or ride the virtual hot-air balloon over the Defence Line. The pavilion serves fresh coffee and lunch with IJmeer views.
Ferries run seasonally April-October only, Tuesday-Sunday. Book tickets online in advance to guarantee a place. Plan at least 2-2.5 hours on the island; the total outing including ferry takes 4.5 hours from Muiden.
