Denver, Colorado, known as the “Mile High City” for its elevation exactly 5,280 feet above sea level, offers far more than a mountain backdrop.

While the nearby Rocky Mountains are visible from almost anywhere in the city, places like City Park and Washington Park offer wide green spaces right in town.

Punakha sits in one of Bhutan’s most fertile valleys, cradled where the Mo Chhu and Pho Chhu rivers meet. For centuries it served as the kingdom’s capital and remains a place rich with stories woven through its fields, temples, and riverbanks.
