Tongjin Hyanggyo is a Confucian heritage complex at 288-21 Gunha-ro, Wolgot-myeon, Gimpo. The KTO lists year-round access and describes taking bus 90 from Ganghwa Bus Terminal to Tongjin Hyanggyo stop, followed by a walk of about five minutes.
The key accessibility warning is that the main approach has no step but is steep. An absence of a kerb does not mean an easy approach for manual wheelchair users or people pushing strollers. Guide dogs are listed as permitted.
The page does not detail wheelchair access inside individual buildings. Contact the site before relying on full interior access, and account for both bus services and the final walk.
