If someone goes missing:

  1. Stop the walk and wait for a short while to see if they turn up.
  2. If they do not turn up, send a couple of members back to search for about 15 minutes.
  3. If they are still not found, detail a search party with experienced members and report progress back to the leader.
  4. If still not found, call the police.
  5. The walk leader should continue with the rest of the party and arrange a rendezvous with the search party.
