Go to the little rocky cove, and go in when the tide goes down. Nereus will appear.
Heracles was assigned to fetch the apples of Hesperides as the eleventh labor by King Eurystheus. The apples were Hera's favorite.
Atlas will go up to Olympus and get apples for you.
The apples were sweet and scented just like other fruits, but they were the fairest ever seen. He traveled to the garden of Hesperides, where he met the river nymphs.
Heracles went to the little cove and hid until the tide went down. When the tide went down, he saw white seagulls creating a huge wave coming from the sea.
The wave created a green wall, where an old man named Nereus popped out of. When he woke up from a deep sleep, Nereus told Heracles to find Atlas, and he would grab the apples for him.
Heracles went to go find Atlas, so he could go to Olympus to get the apples for him.
Atlas and Heracles had a deal. If Heracles held up the sky for Atlas, he would go grab the apples. Atlas came back with the apples and offered to take them back for him. Heracles faked willingness and took the apples back himself.
