Canoeing on Lake Duluti. Canoe trips are a fun and relaxing way to see nature from a different angle: from the water! You will use a boat to get to Lake Duluti, a small crater lake close to Arusha town. In the hour-and-a-half that you glide over the calm water of this beautiful little lake, you can see eagles, kingfishers, and darters. The lake is surrounded by trees.
