Ethiopia’s largest lake is a place of great natural beauty, as well as great cultural and historical significance. Of its 37 islands, roughly 20 encompass ancient churches and monasteries dating back as far as the 14th century and containing exquisite frescoes and antique treasures. Lake Tana is also an excellent bird-watching site, with many migratory and endemic species inhabiting the area’s wetlands, woodlands and rocky outcrops.
