How do you find the Gemini constellation?

The first and easiest way to find Gemini is to use Orion as a guide to Castor and Pollux. 1. Locate Orion by its 3 bright stars making up Orion's Belt. 2. Track Northwest from Orion until you find the two bright stars pointing downward at a southeastern angle, these are the heads of the twins (Castor and Pollux). 3. Continue Southeast from Castor and Pollux and trace out the rest of the constellation.
