Split is the main jumping-off point for exploring all of Dalmatia, not just Central Dalmatia. From there it is easy to catch a bus, boat, train, or rental car in any direction to see everything Dalmatia offers, on and off the beaten path. In each direction of Split, there are many nearby places worth exploring. Directly south of Split are the islands of Brač and Šolta, both easily accessed by ferry in less than one hour. Northeast of Split is Omiš and the Cetina river valley, and directly west across the bay from the Split port is the ancient walled city of Trogir, which can be reached in 20 minutes by taxi boat. To the north of Split and a 30-minute drive are the Klis fortress and the Vranjaca cave, which offer spectacular views over Split and are often overlooked by tourists. Southwest toward Dubrovnik is the Makarska Riviera with its plethora of hidden coved beaches that can be reached in about 45 minutes by car from Split. In the opposite direction of Makarska, along the main coastal highway, there is Krka National Park, about a two-hour drive from Split but also accessible by boat via Skradin Bay. Međugorje, which is across the border in Bosnia and Herzegovina, is less than a two-hour drive from Split and is also a short distance from Mostar.
