Odda municipality was very mountainous and the settlements were all located in valleys. Because of the many mountains, there were many large waterfalls including Låtefossen, Espelandsfossen, and Tyssestrengene. There are also many large lakes such as Sandvinvatnet, Votna, Valldalsvatnet, Røldalsvatnet, Ringedalsvatnet, Langavatnet, and parts of Ståvatn. On top of the high mountains in western Odda is the vast Folgefonna glacier, including the Buarbreen glacier near the town of Odda. Part of Folgefonna National Park is in Odda. The western part of the municipality sits on top of the southern part of the Hardangervidda plateau, which also includes part of the Hardangervidda National Park. The mountains Kistenuten and Sandfloegga are located on the plateau.
