The Arch dive starts at The Arch - a large natural rock arch big enough for 5 divers to swim through together.

Divers continue to meet up with parts of Moon Island's southern wall and a series of caves - the first being the In/Out Cave - go in one side of a rock collapse and out the other, the next cave is hidden behind some large boulders (the Secret Cave). Divers then cross an area of kelp (look out for weedy seadragons) before reaching #3 Cave - the second biggest cave around Moon Island. After leaving #3 the Moon Island wall drops to just a rock platform; swim over this and find the fissure - drop into that and pass through the Squeezy (a narrow swim-through).
