Want a nature day near Seoul without committing to a summit climb? Uiryeong Pass is a cross-park trail with two entrances, but winter weather, entry cutoffs and the Korea National Park Service’s route-specific reservation rules can change your plan. Check the park’s latest notice and forecast before you travel, and again before setting out. If the trail is closed or conditions exceed your experience or equipment, choose an indoor day instead.

1. Check the exact trail and reserve if required

Open the official Uiryeong route information. The park lists Uiryeong (우이령) as a route between U-i and Gyohyeon visitor support centres. Its posted operating arrangement says weekends and public holidays require a reservation, while weekdays do not, under the current notice; verify whether that arrangement still applies to your date. A reservation is not a guarantee against a weather closure.

When a reservation is required, select 북한산 우이령 on the official trail reservation page. We have not checked availability or completed a booking for any specific date.

As checked on 9 November 2026, the park lists hours of 09:00–16:00 and an entry cutoff of 15:00 from December to February. Check the current date-specific rule before traveling. If booking or notices are unclear, contact the relevant support centre shown on the route page.

2. Check weather and closure separately

  • Check the Korea Meteorological Administration’s severe-weather status for the relevant area, as well as the local forecast. An absence of a warning does not mean the route is ice-free.
  • Open Bukhansan’s national-park page and select the real-time control information; check the exact trail section, not just the park name.
  • If a route notice is unclear, call the park using the number on the official route page. Follow all posted closures and staff directions. Weather warnings or other conditions may trigger restrictions; do not assume every warning closes every route.

3. Choose a safe day and a practical return

The official route page lists an approximately 3.5 km point-to-point route between the support centres. U-i is at 서울 강북구 삼양로 181길 349; Gyohyeon is at 경기 양주시 장흥면 석굴암길 93. Find U-i in Naver Map or Gyohyeon in Naver Map, then check the destination against the park's address. Before leaving, choose your entry point and work out how you will return from the other end. The park lists public-transport directions for both sides and states that there is no parking at the route; verify the current service with the operator before travel. Do not treat the listed walking time as a guarantee in snow or ice.

For a winter walk, bring warm layers, gloves, a charged phone, water and footwear suitable for the conditions; seek the park’s advice about additional traction equipment. Tell someone your route and expected return. If ice, visibility, cold or fatigue makes the route unsafe for your group, turn back before committing further. Respect the entry cutoff and give yourself daylight and a margin for unexpected delays. The government’s heavy-snow safety guidance advises limiting outings during heavy snow and taking care when walking on slippery surfaces.

If you cannot go

Postpone rather than entering a closed trail. If you reserved, check the official cancellation rules on the route page and cancel as appropriate. For an indoor Seoul day, use the rainy-day Seoul guide, confirming each venue’s opening status independently. The backup is an editorial suggestion, not a guarantee that every venue will be open.

Emergency: If someone is in immediate danger or needs rescue, call 119 and describe your location; use the trail or support-centre name when possible. Korea Tourism Organization hiking safety.
