Treach-ar-Salus (Île-d'Houat)

Treach-ar-Salus is the south beach of Île-d’Houat and is described as having crystal-clear water with chop and small-to-medium waves. The beach is sandy, and conditions are influenced by tides (with tidal currents noted as potentially strong), so choosing the right tidal window is important. Water depth is reported as shallow near shore and deeper further out, with small shore break. Wind options cluster around southerly directions (S, SSW, SW, WSW). The spot is described as being sheltered from north winds (cliffs provide some shelter in northerly directions). Wind is most often characterized as a mixed/frontal Atlantic pattern, with occasional summer sea breezes that can reinforce the gradient wind; wind reliability is therefore described as moderate and dependent on weather systems or summer sea-breeze development. Typical kite conditions are commonly reported in the ~12–25 knots range. For kitesurfing, sources describe flat to freeride-friendly water with chop and small waves, favoring S–SW–W winds and a remote island feel. Skill expectations vary slightly by source, but the spot is commonly framed as intermediate-to-advanced due to isolation and currents. Kite sizing commonly cited is around 9–12 m². Windsurfing and wingfoiling are also described as possible, with freeride/foil styles, though island access makes transporting gear challenging (and intermediate skill is generally expected). Access is boat-only from Quiberon, followed by a walk from the ferry/port to the south beach, and summer conditions include specific swimmer-related restrictions. Hazards repeatedly mentioned include ships and tidal currents; rocks at the bay’s eastern and western ends are also noted, along with maritime traffic further out. Rescue availability is described as limited, with SNSM access via VHF Channel 16, and riders are advised to respect designated bathing/swimming areas in July–August.
