For our summer holiday we went back to Asia, but this time with a specific purpose: visit the largest cave system in the world in Phong Nha Ke Bang, Vietnam. The caves were an incredible adventure! We combined this trekking with a trip through the North and Center of the country, absorbing the culture, the cooking, and the scorching sun. Rice terrasses could also not be missing from our trip, and a trekking in Pu Long including homestays went above and beyond our wildest dreams.
