Nature World, at 200 Mageompo-gil in Nam-myeon, Taean, is a garden known for its evening illuminations. The KTO listing gives a general 7–9:30 p.m. window, but explicitly says hours vary by month and the site may close in rain or severe weather. Verify the lighting schedule and admission cutoff for your actual date with the operator.
The accessible-tourism page describes a level, step-free entrance but dirt and stone sections along the approach. Wheelchairs and strollers are available on a first-come basis; an accessible toilet and nursing room are also listed.
Uneven ground is harder to navigate after dark. Visitors using mobility aids should check both the night-time opening and live loan availability.
