Lekafossar, also known as Tungnaárgljúfurfossar or Tungnaárfossar, are waterfalls in the Sigöldugljufur valley. Due to their placement in the landscape, I consider them among the most charismatic waterfalls in Iceland.

The waterfalls are located in the interior of Iceland, near road F208 in the Sigöldugljufur valley. For precise navigation to the site, refer to the Sigöldugljufur canyon page.
