Took a taxi from our hotel Holiday Inn City in Topkapi, was about $10 one way, worked best for our family of 4 with 2 kids (10 and 12 years old). You can reach by public transport as well. Tickets were a bit pricey in my opinion, but the worse part is that you have to pay extra for all the fun things for kids to do inside the park, the interactive additions. We visited a similar park in Holland (Madurodam) and all the interactive activities there were included. In Istanbul, no. Inside the park you have to get a card that you load with money and you then use that card for kids to play with a remove boat or pedal a bike to move a ferry. Some activities simply took the money and didn’t perform. My kids wanted to hear some anthem of famous soccer teams and the machine deducted the money from the card but didn’t play anything. We tired twice and lost money both times. Another activity, the talking tree, was in Turkish. Again, you pay money and have no idea what’s going on. Unless you speak Turkish of course. Another activity was closed (laser games). You have to pay extra to take a trolley around the park as well. I wouldn’t recommend the place for a visit unless you live in Turkey and/or a Turkish citizen. My kids had no idea nor, honestly, did they care about Turkish historical buildings. It’s interesting for an adult to read about, yes, but then as as adult you’d better visit these locations in person (at least in Istanbul). Clean grounds though, the park is well kept.
