Crucial Safety Rules

  • Do not cross if water touches rocks: Turn back immediately.
  • Never attempt to swim the Sound: Extreme tidal races make water impassable.
  • Return walk: Allow 1.5 hours return journey from Outer Head.
  • Rapid tidal surge: Water levels rise vertically up to 2.5m per hour (4 cm/min).
