A small, landlocked nation of velvety green peaks, terraced farmland and Nile-fed grasslands, Rwanda is a place of tremendous beauty, yet unsurprisingly it’s a latecomer to the luxury travel circuit. Many people associate this East-Central African country with the 1994 genocide in which between 800,000 and a million Rwandans were killed over a 100-day span. Twenty-five years later, Kigali, the capital, is a fastidiously clean conference hub, and the Rwandan government makes maintaining the peace a priority.
