The 13th- to 16th-century archeological sites of the Majapahit Hindhu Kingdom are located just 90 minutes from Surabaya. Specifically, many ancient temples can be found in the Trowulan area, near Mojokerto city. Begin your day of learning with a visit to the Trowulan Archeological Museum, which houses superb examples of Majapahit sculpture and pottery from East Java. From there, continue to the Segaran Pool—the largest ancient pool used as a place of recreation for the Majapahit family. The most interesting ruins here include the entrance to the Bajang Ratu Temple, with its strikingly sculpted Kala Heads, and the Tikus Temple used for ritual bathing and cleansing. Leave the Trowulan area and head to a local restaurant for lunch, returning to the ship (a one-hour drive) in the late afternoon.
