As a lava cave, the site itself is underground and naturally sheltered from rain, but on-site parking is not available and rain-safe details are not officially specified.

• Type: lava cave (UNESCO World Natural Heritage site)
• Hours: 09:00–18:00, last entry 17:10
• Closed: first Wednesday of every month
• On-site parking: not available
• 'Rain-safe' and indoor/outdoor flags: not specified in source data

Based on place_type (attraction) and canonical_name_ko indicating a cave, plus operating.open_hours_raw, operating.closed_days_raw, and operating.parking_available. experience_attributes.rain_safe and experience_attributes.indoor_outdoor are both null, so the rain-safe judgment relies on the cave nature of the site rather than an explicit field.
