Spots still open for Nov, Dec guided walks
Guided walks at Sisters' Islands are conducted twice a month from August to December, except for October due to unfavourable tidal conditions.
Spaces for August and September have been filled, but places are available for the walks on Nov 23 and 24 and Dec 22 and 23.
Registration for the walks in each month opens on the first day of the previous month.
The walks this year are free and each session is open to a maximum of 45 people.
