About this water

A compact limestone Arga tributary in easternmost Navarra's trout zone. The Areta drains from karst plateaux and flows through narrow alpine valleys with significant drop. Clear, alkaline freestone with pocket-water runs and short pools holding wild browns with good size distribution. Technical short-line nymphing and dry fly. Rapid limestone spate response moderated by karst storage. Access from Aoiz or Orbaieta.
