Rano Raraku is the workshop where the island's mythology was made. The soft volcanic tuff of this single crater was the source of almost all the 900-plus moai found on Easter Island, and nearly 400 statues are still here — abandoned at every stage between rough block and finished figure. Some have made it onto temporary platforms partway down the slope, where they appear to be walking towards the coast; others lie in unfinished trenches on the flank of the volcano, with chisel marks still visible.
A path winds up the outer slope and over the rim into the crater, where a freshwater lake is ringed by yet more statues, including a kneeling moai unique on the island. The full circuit takes around two hours. Park rangers are strict about staying on the marked paths — the ground is fragile and the statues are slowly being eroded by visitor traffic.
