If you drive from Taipei to Yilan, this Castle Cafe is a good coffee break option. Locating in the middle of the hill, Castle Cafe overlooks Pacific Ocean and the famous Turtle Hill Island (Guishan Island) of Yilan. A spectacular view! Built and owned by King Car Group, the Castle is open for public. There’s no obligation to buy coffee at Mr. Brown Coffee at the Castle. You are free to hang out and picnic outside and take pictures of the building. It is a tourist attraction and certainly a nice place to visit with great view.
