Best things to do in Cluj-Napoca

Hike in one of the lushest natural areas in Romania, Cheile Turzii. Visit the 2.9 km (1.8 mi) gorge nestled in the Apuseni Mountains, and explore the surrounding forests and limestone cliffs dating back to the Jurassic era. If you like to rock climb, this area is one of the most popular spots for it in the country. Look for the approximately 60 caves in and around the 300 m (984 ft) tall cliffs and rock formations. Also, keep an eye out for the gorge's 67 different animal species.

At Gradina Botanica "Alexandru Borza", see the Amazonian water lilies--a lotus with gigantic leaves and white flowers--which turn pink as they mature. The garden supports three greenhouses with topical and sub-tropical species, a herbarium with over 635,000 plants, a museum, and an institute. In the Roman garden, look for archaeological ruins from the Roman colony of Napoca, including the statue of Ceres--the goddess of grain and bread. The Japanese garden, intersected by a brook, features a Japanese-style house.

Board a panoramic wheel and observe the 1,000-year-old stalagmites, or row across a small underground lake at Salina Turda. Romans began unearthing this huge underground mine in the 2nd century. It was closed in 1932 and reopened for tourists in 1992. Old mining machines take visitors through its massive halls, and the textured salt caves also house spa equipment for halotherapy. The pressure and dampness of the caves help in the treatment of asthma and allergies. The mine also features a family entertainment area with ping pong tables and bowling lanes, an echo chamber, a crystal hall, and a 50 m (164 ft) wide and 80 m (262 ft) long hall.

Star-shaped Cetatea Alba Iulia showcases six monumental gates decorated in the early Baroque style and adorned with sculptures of ancient gods. Charles VI commissioned the building of the fortress, which was completed in 1735. The Italian architect laid out the fort as a seven-pointed star with bastions using the building system of Vauban, the leading military engineer of the 17th century. The citadel includes two palaces, a library, a university, a Romanian Orthodox church, and a medieval Catholic church. Try to time your visit to catch the ceremonial changing of the guards. Amenities include a few restaurants and cafes.

Catedrala Sfantul Mihail dominates the center of the city with its massive Gothic silhouette and offers encompassing views from its 76 m (250 ft) clock tower. This 15th-century Roman Catholic church was built partially from donations from the townspeople. On the western portal notice the three coats of arms that represent Sigismund as King of Hungary, King of Bohemia, and Holy Roman Emperor. The interior features some medieval frescoes and the oldest section of the church--the 14th-century altar.
