One subway and a bus ride outside of Amsterdam and you can visit Amsterdam Castle Muiderslot in the town of Muiden. I couldn’t take an overall picture of the castle since they were working on it sorry! It was so hot so I stopped for gelato of course. When you get off at the bus stop in Muiden it looks like there is literally nothing around and there were no signs. Just cross the intersection and walk across the bridge and there’s the town. Keep walking to the main road and you’ll start to see signs for the castle.
