The star of tonight’s episode has to be five-year-old Isla.
From paddling with marine iguanas to swimming with sharks, the little girl with her fearless enthusiasm has truly had a summer like no other.
But before the Halls family head back to the UK, Monty has a life-long ambition to fulfil – looking for sharks on the islands of Darwin and Wolf.
At the northern tip of the Galapagos, they are a haven for 33 species, including the one Monty is desperate to see – the whale shark.
But even here the species is under threat; it’s estimated the number of hammerheads has dropped 95 per cent in the last 30 years.
It couldn’t be more important that this and the next generation do everything we can to protect them now.
