Teza Tea Plantation is a hidden gem nestled in the lush valleys of Burundi's mountains, Established in 1931 during Belgian occupation, this charming estate sits at an altitude of 4500-7000ft above sea level and boasts breathtaking views of rolling hills and thermal springs. Visitors can embark on a short tour to witness the tea harvesting process firsthand. There is a guide from the area that will show you around. They would not let us go inside the factory. You need to arrange your own transport here as it is far off the main road.
The guide had a list of prices for tours, but they were extremely high given other prices in Burundi. We negotiated with him something fair for the short tour. Expect to pay around $10-$40 depending on what you negotiate.
