Planning to hike Hallasan in Jeju Island? Learn everything you need to know about Hallasan National Park, including the best hiking trails, difficulty levels, what to pack, the best time to visit, and essential travel tips.

Standing at 1,947 meters (6,388 feet), Hallasan is the highest mountain in South Korea and the centerpiece of Jeju Island. Located within Hallasan National Park, this dormant shield volcano is recognized as a UNESCO World Natural Heritage Site and attracts thousands of hikers every year.

Whether you're an experienced trekker aiming for the summit or a casual traveler looking for scenic forest walks, Hallasan offers unforgettable hiking experiences surrounded by volcanic landscapes, alpine vegetation, and breathtaking panoramic views.

Why Hike Hallasan?

Hallasan is more than just South Korea's tallest mountain. The park is home to diverse ecosystems that change dramatically with the seasons, from colorful wildflowers in spring to vibrant autumn foliage and snow-covered trails in winter.

Reaching the summit rewards hikers with Baengnokdam Crater Lake, a volcanic crater that remains one of Jeju Island's most iconic natural landmarks.

Even if you don't hike all the way to the top, the surrounding forests and scenic trails provide plenty of opportunities to experience Jeju's unique volcanic landscape.

Choosing the Right Trail

Hallasan offers several hiking routes, but Seongpanak Trail and Gwaneumsa Trail are the only two that lead to the summit.

Seongpanak Trail is the most popular option for first-time visitors. The route is longer but has a more gradual incline, making it the preferred choice for most hikers.

Gwaneumsa Trail is shorter but significantly steeper, making it better suited for experienced hikers looking for a more challenging ascent.

For travelers who prefer an easier walk, trails such as Eoseungsaengak and Yeongsil provide beautiful scenery without requiring a full-day hike.

How Difficult Is the Hike?

A complete summit hike usually takes between seven and ten hours, depending on the chosen route, weather conditions, and hiking pace.

Although no technical climbing skills are required, hikers should have a reasonable level of fitness, as the trails involve long distances and continuous elevation gain.

Proper preparation is essential, especially during colder months when temperatures near the summit can be much lower than at sea level.

What to Bring

Comfortable hiking shoes with good grip are highly recommended, as some sections can become slippery after rain.

Layered clothing is important because temperatures change throughout the hike. Carrying water, energy snacks, sunscreen, and a lightweight rain jacket will also help ensure a comfortable experience.

A fully charged phone or camera is worth bringing, as the summit and surrounding landscapes provide incredible photography opportunities.

Best Time to Hike Hallasan

Spring and autumn are generally considered the best seasons for hiking Hallasan. Spring offers blooming wildflowers and mild temperatures, while autumn transforms the mountain into a spectacular display of red, orange, and golden foliage.

Summer brings lush greenery but also higher humidity and occasional rain.

Winter offers a completely different experience, with snow-covered trails creating one of the most beautiful landscapes in South Korea. However, hikers should always check weather conditions before setting out.

Important Hiking Tips

The summit trail operates with entry cutoff times that vary depending on the season. Visitors planning to reach Baengnokdam Crater Lake should begin their hike early to avoid missing these deadlines.

Weather conditions can change rapidly on the mountain, so checking the forecast before departure is highly recommended.

It's also important to stay on designated trails to help protect Hallasan's fragile ecosystem and preserve its natural beauty for future visitors.

Final Thoughts

Hiking Hallasan is one of the most rewarding outdoor experiences in South Korea. From peaceful forest paths and volcanic landscapes to breathtaking summit views overlooking Jeju Island, every step offers something memorable.

Whether you're chasing sunrise above the clouds or simply enjoying the tranquility of Hallasan National Park, this iconic mountain deserves a place on every Jeju itinerary.
