The easiest plan is the observatory. Walk across the glass section only if comfortable with heights; add a ride only after checking that product's separate rules.
Seasonal hours and admission
The operator lists summer hours as 09:00–18:00, with on-site ticketing ending at 17:00. Winter hours are 09:00–17:00, with ticketing ending at 16:00. Adult admission is KRW 4,000; youth and children KRW 3,000; visitors aged 65 or older KRW 3,000; preschool children enter free. Group rates apply from 20 people. Check the operator's hours and access rules and ticket table for current terms.
Shuttle and conditions
Visitors reach the observatory by shuttle bus; allow time for the ride and any queue. Heavy rain, snow or fog that blocks visibility may restrict viewing. The operating page does not define calendar dates for its summer and winter schedules, so confirm which timetable applies before travel.
The glass-floor walk is optional. Zipwire, alpine coaster, slide and monorail are separate products with their own rules and opening times. Choose the observatory alone if the group wants the view without another activity, and do not assume one ticket covers the rides.
