Ulsan Petroglyph Museum at 254 Bangudaean-gil, Ulju-gun interprets Bangudae and Cheonjeonri rock art. The Korea Tourism Organization official entry (marked revised 21 July 2026) lists three strollers available at the information desk, two accessible parking spaces in front of the museum, a lift and an accessible toilet. It does not establish that four wheelchairs are available to borrow; call the museum to check wheelchair-loan availability and current stock. The separate outdoor Bangudae petroglyph observation deck has a roughly 10-metre sloping approach near the deck. That outdoor route must not be confused with the museum interior: verify permitted parking and surface conditions. Museum entry is free, with general opening 09:00–18:00, last entry 17:30, closed Mondays and January 1 (next day if Monday is a holiday).
