Skill Level

  • Who it's for: Expert
  • Why: Fast, hollow barrel over a shifting sandbar, requires tube-riding skill and the ability to read a complex, tidal-dependent break.

Hazards

  • Shifting sandbars, the bank changes constantly
  • River outflow can create unexpected currents
  • Cold Bay of Biscay water
  • Highly competitive local crew

Local Tips

  • The swell, wind, tide, and river outflow all need to align, check local surf reports obsessively.
  • The estuary town of Mundaka is a UNESCO Biosphere Reserve; the surrounding scenery is spectacular.
