From Jeju City, you can take local buses or a taxi to one of the main trail entrances such as Seongpanak or Gwaneumsa. The bus ride takes approximately 30–40 minutes. If you’re coming from Jeju International Airport, it’s about a 40-minute drive to the park's entrance.

From Seogwipo City, it takes about 45 minutes to an hour to reach Hallasan depending on traffic. Renting a car is a popular option for tourists who want flexibility in their itinerary.

Weather

Hallasan experiences diverse weather due to its elevation. Lower areas may be mild, while higher elevations can be significantly colder, especially in winter.

• Spring (March–May): Mild and ideal for hiking. Cherry blossoms bloom at lower altitudes.
• Summer (June–August): Warm and humid. The mountain provides a cool escape, but rain is common.
• Autumn (September–November): Cool and dry, with brilliant foliage. This is one of the best times to visit.
• Winter (December–February): Cold and snowy at the summit. Hallasan looks magical under a blanket of snow, though hiking conditions can be tough.

Timing

Hallasan National Park is open year-round, but trail access is strictly regulated for safety reasons.

Hiking trails have specific cutoff times. For example, the Seongpanak Trail entrance is usually open from around 5:00 AM to 2:00 PM depending on the season. You must reach the summit before 1:00 PM in most cases.

Always check the official Hallasan National Park website or visitor center for current trail conditions and opening times before visiting.

Why Famous for Hallasan National Park, Jeju?

Hallasan National Park is famous for several reasons. First and foremost, it is home to Mount Hallasan, the tallest mountain in South Korea and a dormant shield volcano that last erupted thousands of years ago. The mountain is also surrounded by volcanic cones called “oreum,” giving the park a unique topography.

It is a haven for biodiversity, with over 1,800 species of plants and 4,000 species of animals. Many of them are rare or endangered, making it an important ecological site.

The park is also known for its spiritual significance in Korean culture and mythology. Locals regard Hallasan as a sacred mountain, and it features prominently in Jeju Island’s legends and history.

Entry and Visit Details

Entry to Hallasan National Park is free of charge. However, you must register before starting your hike on certain trails, especially the summit trails such as Seongpanak and Gwaneumsa.

There are several trails in the park:

• Seongpanak Trail (9.6 km one-way): The most popular and relatively easier path to the summit.
• Gwaneumsa Trail (8.7 km one-way): Steeper and more challenging, but offers better views.
• Eorimok, Yeongsil, and Donnaeko Trails: These do not go to the summit but offer beautiful scenery and shorter hikes.

Restrooms, parking lots, and visitor centers are available near the trailheads. Guided hiking tours can also be arranged.

History and Natural Features

Hallasan was formed by volcanic activity and has shaped Jeju Island’s geological landscape. The crater at the top of Hallasan is known as Baengnokdam, meaning "White Deer Lake." It’s a shallow crater lake surrounded by steep cliffs, and it's a breathtaking sight.

Historically, the mountain was a place of worship and still holds cultural significance. The park became designated as a national park in 1970 and was later named a UNESCO Biosphere Reserve due to its ecological importance.

Although not a place with traditional architecture, the natural “architecture” of lava formations, volcanic rock walls, and diverse ecosystems forms the park’s real structure.

Things to Do

The main activity at Hallasan National Park is hiking. Trails range from easy walks to full-day summit climbs.

• Hike to Baengnokdam Crater Lake for stunning views.
• Enjoy wildflowers and unique plants in spring and summer.
• See the colorful foliage in autumn or snow-covered trails in winter.
• Take photos at scenic spots and rest areas along the trails.
• Visit the Eoseungsaengak Trail for a short and rewarding hike near the visitor center.

Facts and Tips

• Mount Hallasan is a shield volcano, which means it has gentle slopes formed by fluid lava flows.
• The summit area can be much colder than the base — bring layers even in summer.
• There are no food stalls on the mountain — bring your own water, snacks, and supplies.
• Download an offline map or use a hiking app — signs are good, but cell service may be spotty.
• Start early in the day to ensure you have enough time to complete the hike and descend before the cutoff time.
• Wear proper hiking boots and be prepared for changing weather conditions.
