The park contains a massive volcanic crater with a diameter of approximately 10 kilometers.
The 12 Apostoli geological reserve features rock pillars that appear as human figures, created by selective volcanic erosion.
It is home to one of the largest sulfur deposits in Romania, which was mined extensively until the 1990s.
The park protects the Tăul Zânelor, a glacial lake situated at high altitude.
The flora includes endemic species such as the Călimani bellflower and specific Carpathian mountain pines.
Călimani National Park is home to the largest volcanic crater in the Carpathian Mountains, stretching over 20 square kilometers. The park encompasses the Călimani Mountains, characterized by dramatic volcanic formations, alpine meadows, and dense spruce forests. Its distinctive geological feature is the 12 Apostoli reserve, known for unique rock formations sculpted by wind and weather. The highest peak, Pietrosul Călimanilor, reaches an altitude of 2,102 meters. Visitors can traverse a network of marked hiking trails that lead through diverse ecosystems including mountain pine shrubs and wetlands. The park is a protected habitat for brown bears, lynx, and wolves, as well as rare flora like the Swiss stone pine. It serves as an important site for both biodiversity conservation and scientific geological research. Access is primarily managed through the visitor center located in Șaru Dornei.

Bring high-quality hiking boots with ankle support due to the rocky and uneven volcanic terrain.
Carry bear spray and maintain a loud, consistent presence while hiking to avoid startling wildlife.
Check local weather forecasts before departure, as conditions at high elevations change rapidly.
Attempting to climb during heavy fog or approaching wildlife for photos.
High-altitude trails are often inaccessible during winter months due to heavy snow and avalanche risk.
Strictly follow marked trails to preserve volcanic soil; do not pick rare plants; carry out all waste.
