Guci Hot Spring is a scenic thermal recreation area on the slopes of Mount Slamet in the Tegal Regency of Central Java Province, Indonesia, situated at approximately 1,050 meters elevation on the southern flank of Java's second-highest volcano — an active 3,428-meter stratovolcano whose ongoing geothermal activity warms the springs that have made Guci a beloved weekend destination for Central Javanese families. The bicarbonate thermal waters are traditionally valued for skin conditions and musculoskeletal ailments, with multiple natural pool complexes catering to different temperatures amid the cool mountain forest environment. The surrounding pine forests, waterfalls, and the dramatic volcanic landscapes of the Slamet massif create an invigorating highland backdrop for this accessible Central Java hot spring retreat.

Insider tip — Guci Hot Spring sits on the northern slope of Gunung Slamet, Central Java's highest volcano and one of Indonesia's most active, at around 1,050 m altitude. Fourteen spring sources feed pools and waterfalls that cascade through lush montane forest. The cool mountain air and warm mineral water create a uniquely comfortable microclimate even at midday on the equator. Weekend crowds from Tegal and Purwokerto can be intense; mid-week visits offer a far more tranquil experience.
