Indonesia's Temples and Volcanoes
Indonesia’s essential sights split into two very different categories: monumental religious architecture on Java, and active volcanic geology stretched from East Java to Lombok. Neither is a quick stop.
Borobudur, Central Java
The world’s largest Buddhist monument, built in the 8th and 9th centuries, carries 504 Buddha statues, 72 perforated stupas and 2,672 relief panels across three circular terraces. The site is open every day of the week, including Monday, and climbing the monument itself for sunrise is available again through the official Manohara Sunrise Experience, capped at roughly 100 climbers a day, departing before dawn from Gate 7. A separate ground ticket covers the park and monument base without the climb; a climb-up ticket adds the ascent, woven Upanat sandals to protect the stone, and a timed guide-led slot. Prices have moved since 2024 and the exact current split is unsettled, so treat any number you see as approximate and check ticket.borobudurpark.com before booking. Book Borobudur sunrise tickets on GetYourGuide .
Prambanan, Yogyakarta
Indonesia’s largest Hindu temple complex and the second-largest in Southeast Asia, built around 850 CE, is dominated by three central shrines: the 47-metre Candi Shiva, Candi Brahma and Candi Vishnu, all carrying Ramayana relief narratives. As with Borobudur, foreign-visitor ticket prices have shifted in the last two years, so check current single and combined Borobudur-Prambanan ticket options at the official ticketing site before you travel. The complex opens daily.
Uluwatu and Tanah Lot
Pura Luhur Uluwatu perches on a 70-metre limestone cliff above the Indian Ocean, home to a resident troop of long-tailed macaques known for snatching sunglasses, and stages the Kecak Fire Dance at 6pm against the sunset (temple entry IDR 50,000 adult, Kecak ticket IDR 150,000). Pura Tanah Lot sits on an offshore rock reachable on foot only at low tide, with a freshwater blessing spring beneath it (foreigner entry IDR 75,000 adult).

Kawah Ijen, East Java
A 1-km-wide turquoise crater lake with a pH below 0.3, Kawah Ijen is best known for its electric-blue flames, ignited sulfuric gas visible only in full darkness before 4:30am. A medical health certificate has been mandatory for every hiker since January 2024, available at the Paltuding entrance health post, and a functional gas mask is required for the choking sulfur dioxide fumes near the crater (rental IDR 50,000 at basecamp). The 3 km trek from Paltuding, opening at 2am, climbs a steep 30-35 degree grade for 1.5-2 hours; foreigner entry runs IDR 100,000 on weekdays and IDR 150,000 on weekends, booked at East Java conservation office ticketing .
The verdict
See Borobudur at sunrise and Prambanan the same afternoon if you only have one day in Yogyakarta; Kawah Ijen deserves its own separate trip, since a 2am basecamp start after a full temple day is a bad combination. For the guided jeep and ranger-led versions of these sights, see the Indonesia attraction tours guide .
Before you go
Rent gas masks and check health-certificate requirements for Kawah Ijen a day ahead in Banyuwangi; the Paltuding health post issues certificates on the spot, but only during its operating hours before the midnight climbs.
