Because of this due-east orientation, the sun sets directly behind the restaurant on the inland side. You will not experience a classic direct sunset view from your table at Kaio. The famous blazing red sunsets of Zanzibar belong exclusively to the western coastlines, such as Stone Town, Kendwa, or Nungwi.
What Kaio delivers instead during the evening hours is a highly unusual, soft, reflective back-lighting. As the sun drops behind the building, it throws an indirect, glowing illumination across the water in front of you, causing the entire lagoon to take on a luminous, painterly quality that landscape photographers prize.
