This 25-day eco-conscious trip takes you through Japan and South Korea, covering over 1,200 miles from Tokyo's neon streets to Jeju Island's volcanic coast. You'll stay at sustainable hostels and Geumsunsa Temple, where a traditional Buddhist temple stay includes meditation with monks and vegetarian meals. Hike the Jeju Olle Trail along dramatic cliffs, cycle through Kyoto's backstreets to Zen temples, and trek Seoraksan National Park's mountain trails. Travel mainly by local trains and buses, including Japan's efficient shinkansen bullet train, keeping your carbon footprint low while visiting UNESCO sites like Kiyomizu-dera Temple and Seongsan Ilchulbong.
