I have heard about temple stay programs in Korea where you can live at a Buddhist temple for a few days?

Temple stays (템플스테이) are one of the most rewarding things you can do in Korea, and the official program through the Cultural Corps of Korean Buddhism makes it easy for foreigners. About 140 temples participate, with around 30 offering English-language programs. Book through eng.templestay.com, which has full English booking, prices, and schedules.

There are two main types: Experience programs (체험형) run 1 to 2 days at 50,000 to 100,000 won per night and include 108 prostrations, tea ceremony with a monk (다도), temple meals (발우공양), Zen meditation (참선), and a temple tour. Resting programs (휴식형) are more flexible at similar prices, letting you simply meditate, walk forest paths, and relax with minimal scheduled activities. Wake-up is around 4am for morning chanting at most temples, but resting programs let you sleep in. Bring loose comfortable clothes (some temples provide gray uniforms), warm socks, and an open mind. Popular English-friendly temples include Golgulsa near Gyeongju (martial arts focus, sunmudo), Beomeosa in Busan, Magoksa in Chungnam, and Geumsunsa in Seoul, which is the most accessible if you only have one night and want to try it close to the city.
