8 clusters of ancient buildings at the foot of Mount Song, including Shaolin Temple, the oldest astronomical observatory in China, and a 1,500-year-old academy.

Shaolin Temple is the draw, and despite the commercialization (kung fu schools, ticket tiers, the pagoda forest Instagrammers), the Pagoda Forest — 240+ stone pagodas from the Tang through Qing dynasties, each a tomb for an abbot — is the most evocative cemetery I have walked through in China. The Gaocheng Observatory was the bigger surprise: a brick platform with a 31 m stone sundial, where astronomers in 1276 measured the solar year to within 26 seconds of the modern value. I was alone there on a weekday, and the stillness of a site that quietly changed world astronomy was more affecting than the kung fu theater at Shaolin.
Both. The temple complex was largely reconstructed after a 1928 fire destroyed most original buildings. The kung fu performance is staged for tourists. However, the Pagoda Forest (240+ tomb pagodas) is genuine, the temple remains an active Buddhist monastery with resident monks, and the surrounding kung fu schools train 10,000+ students in authentic Shaolin martial arts. Go for the Pagoda Forest and the cultural significance, not for an "undiscovered" temple experience.
Seven other UNESCO-inscribed clusters: the Gaocheng Observatory (1276, one of the oldest astronomical observatories in the world), Songyang Academy (ancient Confucian academy), Zhongyue Temple (the largest Taoist temple on the five sacred mountains), Shaoshi Tower and Qimu Tower (Han Dynasty stone gate towers, 118–125 AD), the Huishan Temple, and the Chuzu Temple. Most visitors only see Shaolin. The other seven sites receive a fraction of the visitors.
Bus from Zhengzhou Long-Distance Bus Station (opposite the train station) to Dengfeng: 1.5h, ¥30. From Dengfeng, local bus to Shaolin Temple: 30 min (¥5). Or HSR to Luoyang Longmen Station and bus to Dengfeng: 1.5h. A private car from Zhengzhou: 1.5h (¥400–500 round trip).
Yes — several kung fu schools near Shaolin Temple accept short-term foreign students. The Tagou Martial Arts School (the largest, 30,000+ students) offers day classes (¥300–500) and multi-week programs. The Shaolin Temple itself does not offer tourist kung fu classes — you train at the surrounding schools, not inside the temple.
1 full day: Shaolin Temple (morning) + 1–2 other clusters (afternoon). 2 full days: Shaolin + all 7 other UNESCO clusters at a relaxed pace. Most foreign visitors allocate 1 day and see Shaolin only, which misses the other equally significant sites.
