The retreat schedule, full as it is, includes substantial breaks during the day—two hours after the breakfasts and three hours after lunch on Sunday. Doing nothing or lying about reading could be a very good options during these times.
However if you like, we have made some maps for a pair of walks that could each be covered in somewhere between one hour and an hour or a half.
Alternately you could walk in to Gembrook which is about six kilometers away: in which case you could arrange to be picked up.
