biggest six flags roller coaster
Six Flags open world's tallest, steepest and fastest wooden roller coaster. Daredevils will be flocking to Gurnee in Illinois this summer for the chance to take on Goliath - the world's tallest, steepest, fastest roller coaster. The latest attraction which opened at Six Flags Great America on Thursday is a wooden roller coaster that breaks three world records. Those brave enough to take a ride on it will be plunged down a 180ft near-vertical drop, as the roller coaster twists and turns at speeds of up to 72mph.
