Colossa

Colossa, also known as The Island of the Cyclops, was one of the primary settings for the 1958 mythological fantasy movie The Seventh Voyage of Sinbad.

Geography
Of possibly volcanic origins, Colossa was a large island located somewhere in or near the Persian Gulf which featured high range of mountains towards its centre. Its countryside featured many rocky outcrops and canyons, but was still sprinkled with lush fields, forested ranges and several long sandy shores.

Sokurah's Lair
The evil sorcerer Sokurah kept a sanctuary in a cavern at the bottom of a deep ravine close to one of Colossa's many beaches, where he practiced his dark arts. To keep his possessions safe when not in residence, Sokurah kept the dragon Taro chained in the entrance tunnel ready to attack any who were foolish enough to try to breach his privacy.

Red River
Sinbad's thirsty crew at one point came across a river which ran red, and Sokurah told them it would be death to drink from it. Later the crew did indeed drink from the river, finding its water to taste like wine, and celebrated their discovery by bathing there. However, those who slaked their thirst were soon killed by the Cyclops, suggesting that the water was itself not poisonous, but that it was instead a mystical property of the liquid which brought on their demise.

Eyries
At the peaks of the mountains in the centre of Colossa rested the eyries of the Rocs. Sinbad and his crew discovered a hatchling in one of these nests and killed it, cooking and eating the carcass before the mother Roc descended to kill all of the men bar Sinbad, whom she dropped into another, higher, eyrie. Sinbad was able to climb from the nest however, and effect an escape.

Valley of the Cyclops
There was a lengthy valley running through part of Colossa which was the primary habitation of the giant humanoids known as the Cyclops, which gave the island its moniker. At least one Cyclops is known to have made its lair there, and when Sinbad's men caught its attention, captured and attempted to roast and eat them. It kept a stone "cave" there, within which it kept the valuables left over from those unfortunate humans who had previously become its dinner.
