One ticket to the aquarium and the Museum of History. Everything goes slowly together in 40 minutes, small buildings and pools.
It's beautifully done, and it's worth visiting with children if you have time. The entry is 25 dirhams, which corresponds to
A small but interesting museum. The ticket here was simply taken along with the ticket to the Sharjah Aquarium - and now it has fully justified itself (for example, compared to Dubai). There is also a great playground next to the museum.
The museum is about ships, cool, but not everyone will come in, there are few boats and ships. It takes literally 35-45 minutes (if you watch each exhibit for 5 minutes)
