Not far from the riverside, flower RM1/person can cross the river to visit the castle, or you can walk a little far to the bridge across the opposite side to the castle (it is recommended to take the ferry, save time and have no fun). The castle visit fee is RM20 per person, equivalent to RMB33, the historical interest is still very strong, if the English is good and the history is very strong, friends who have a lot of history can go in and spend some time reading the story, because only Malay and English interpretation. We stayed in it for almost two hours, and Mr. was interested in history, and although I was not familiar with it, there was a general understanding of the history of Sarawak through some of the items displayed and the interpretation of history.
