Hallasan

Hallasan is the highest mountain in South Korea and one of the country’s most famous National Parks.

The mountain (technically a dormant volcano) sits right in the center of the island and there’s several hiking routes around it, from short trails to much more challenging hikes that take you to the summit. If you’re not sure about hiking on your own, this is a great guided tour on Mount Hallasan.

Jeju Stone Park

This cultural park and museum is one place I recommend to everyone visiting Jeju, as long as you’re interested in local culture and history.

Entry is just 5,000₩ (free for children), and includes access to the park, the traditional village, and the museum. You can easily spend an entire half day or full day here and it’s a great way to learn more about the island.

Jeju’s Waterfalls

Jeju is home to many beautiful waterfalls, specifically around the southern coast near Seogwipo. They’re typically right on the coast, and are surrounded by lush foliage, adding to the “Hawaii of Korea” nickname. Two of the most popular are :

Jeongbang Waterfall is one of the few waterfalls in Korea where the water falls directly into the ocean.

Cheonjiyeon Waterfalls is another popular stop, with a walking path that leads you to 3 different waterfalls.

Visit a Tangerine Farm

Jeju is famous for its tangerines, and you’ll see citrus farms (and cute merchandise) all over the island.

Depending on which season you’re visiting, in the fall/early winter you can visit farms where you can pick your own fruit or buy fresh tangerines and other citrus products (peak harvesting season on Jeju is from November to December).

Explore the Manjanggul Lava Tube Area

Like I mentioned above, Mount Hallasan is actually a dormant volcano – and is the reason the island looks the way it does. Not only are there black lava beaches and plenty of unique rock formations, but there’s also lava tubes on Jeju Island.

Manjanggul Lava Tube is one of the most popular to visit, but you’ll want to check current operating status before visiting, lately it’s been closed on and off due to conditions of the caves.
