Bromo Tengger Semeru National Park
Being the largest volcanic region in the province, Bromo Tengger Semeru National Park covers a massive area of 800 square km in the center of East Java. Visitors who have an eager interest in volcanic activities must come to the park and witness the smoke of ashes coming from Mount Semeru,an active volcano that rises 3,676 meters above sea level.Bromo Tengger Semeru National Park is the only conservation area in Indonesia that has a 10 km sea of sand called Tengger,from which four new volcanic cones have emerged. Those volcanic cones are Mount Batok (2,470 m), Mount Kursi (2,581 m), Mount Watangan (2,661 m), and Mount Widodaren (2,650 m). However, Mount Bromo is still the only one that is active.Temperatures at the top of Mount Bromo range about 5-18 degrees Celsius.Heading south of the park is a rolling upland plateau divided by valleys and decorated with several scenic lakes reaching to the foot of Mount Semeru.
Ijen plateau or known as ‘Kawah Ijen’ is highly recommended to mountain buffs and hikers. The Plateau was at one time a huge active crater, 134 sq km in area. Ijen is a quiet but active volcano, and the landscape is dominated by the volcanic cones of Ijen (2,368 asl) and Merapi (2,800 asl) on the northeastern edge of the Plateau, and Raung (3,332 asl) on the southwest corner. The vent is a source of sulfur and collectors work here, making the trek up to the crater and down to the lake every day.
Overland travels from Yogyakarta to Bali, crossing hills, plateau, and volcano view will not make you disappointed. Feel the hospitality of the local peoples by staying at Cemoro Lawang Bromo Tengger Semeru Park, crossing the savannah by jeep and horse, and see sunrise from the best view Bromo Mountain.
Then you will get experience trekking Ijen Mountain for about 2 hours, and down to crater looking blue fire.
Last trip is to Bali Island. The car can cross to Bali by ferry boat, and you stay one night at Lovina (west Bali) to see dolphins in the wild.
