Privately-run and municipal shelters as well as rescue groups exist in most cities throughout Korea and many of them welcome expat volunteers. Help with cleaning, grooming, exercising, feeding, watering, and socializing animals is commonly needed. Many places need help with basic maintenance of their facilities as well.
Visiting once or regularly is always worth it! The animals are grateful for every minute you can spare.
Search the animal shelter listings  to find a volunteering program. Contact the shelter using the information provided in the listing to find out whether they have organized volunteer visits or an informal drop-in style, as well as what to bring and what kind of projects are underway.
If a shelter you know could use more volunteers, please post a message about it on their listing page and invite others to join you on a shelter trip.
