'''Sustainable Jeju Travel'''

Jeju Island is establishing itself as a sustainable tourism destination where visitors can enjoy nature while protecting it through <i>oreum</i> trekking, the Jeju Olle Trail, and eco-friendly travel programs.

Jeju is home to approximately 360 parasitic cones (<i>oreum</i>) surrounding Hallasan Mountain. Among them, Geomunoreum is the central cone of the Geomunoreum Lava Tube System, which forms part of the UNESCO World Natural Heritage Site “Jeju Volcanic Island and Lava Tubes.” Standing at 456 meters above sea level with a circumference of 4,551 meters, Geomunoreum is a volcano that formed a lava tube system and holds exceptional geological value. Visits operate on a reservation basis, with options including the summit course (approximately 1 hour), crater course (approximately 2.5 hours), and full course (approximately 3.5 hours). Reservations can be made online on a first-come, first-served basis starting from the first day of the month prior to the desired visit date, and same-day reservations are not possible. Besides Geomunoreum, various parasitic cones such as Yongnunioreum, Abuoreum, and Baegyagioreum are available, each offering unique characteristics and difficulty levels suitable for different fitness levels.

Launched in 2007, the Jeju Olle Trail is a circuit trail that connects the entire island along Jeju’s coasts and villages through a total length of 437 kilometers across 27 courses (comprising 21 main island courses, plus offshore island and alpha courses). “Olle” is a Jeju dialect word meaning a small alley leading from the main road to one’s home, embodying the hope that this trail would connect Jeju with the world. Each course takes an average of 4 to 6 hours and consists of diverse paths including village roads, coastal roads, and forest trails, providing encounters with Jeju’s everyday beauty away from commercial tourist attractions. For walking the Jeju Olle Trail, it is advisable to prepare sneakers or trekking shoes, sufficient water, a hat, and sunglasses. By purchasing an Olle Passport (20,000 won), visitors can collect stamps installed at the starting point, midpoint, and ending point of each course to record their journey. The Olle Passport can be purchased at Jeju International Airport, the Jeju Olle Travel Center, Jeju Olle official information centers, or as a mobile passport through the “Olle Pass” app. Those who complete all 27 courses receive a completion certificate and medal.

Alongside this walking travel culture, Jeju Island is expanding environmental protection throughout tourism through the “2040 Plastic-Free Jeju” policy. The Blue Cup Service provides reusable cups to tourists visiting Jeju. Visitors can borrow cups for 7 days by paying a deposit on the first floor of Jeju International Airport, and the deposit is refunded upon return. Anyone—individuals, groups, residents, or travelers—can use the service throughout Jeju, and some cafes offer beverage discounts when using Blue Cups. “E-RUN Trip” (short for Eco-Run) is an eco-themed travel program combining sports and environmental missions, including activities such as plogging and visiting eco-friendly zero-waste shops.
