If a drop from 200-plus feet at speeds exceeding 84 miles (135 kilometers) per hour doesn't make you ridiculously nervous, perhaps you'd like to raise the bar. The Kingda Ka roller coaster at Six Flags Great Adventure in New Jersey might be more your style.

This giga coaster -- a super-high coaster characterized by heights above 302 feet (92 meters) and speeds above 93 miles (150 kilometers) per hour -- is both the tallest and fastest steel coaster in the world, and it also has the highest drop [Intamin]. The ride may only last 50 seconds, but those seconds are pretty intense [source: Ultimate].

Set in motion with a powerful hydraulic launch, Kingda Ka starts out horizontally as it shoots from zero to 128 miles (206 kilometers) per hour in 3.5 seconds. It then rockets 45 stories high, or 456 feet (139 meters), before dropping 418 feet (127 meters) in a 270-degree spiral twist at more than 100 miles (161 kilometers) per hour. It wraps up with a 129-foot (39-meter) hill that provides riders ample airtime [source: Ultimate].

Another giga coaster, Millennium Force, broke 10 world records when it was introduced in the year 2000. Although it no longer holds the records for tallest and fastest full-circuit coaster, polls still consistently rank it as one of the top steel roller coasters in the world.

Located at Cedar Point in Ohio, Millennium Force starts out by climbing a 310-foot (94-meter) hill right next to Lake Erie. The 6,595-foot (2,010-meter) long coaster includes several hills approaching 200 feet (61 meters), two dark tunnels, three overbanked turns and an impressive 300-foot (91-meter) drop at a near vertical 80 degrees. The coaster has a top speed of 92 miles (150 kilometers) per hour and so far has provided 2 minutes and 20 seconds worth of excitement to more than 12 million riders [source: Ultimate, Cedar Fair].

Both Kingda Ka and Millennium Force were built by Intamin, the same company responsible for popularizing the term mega coaster. Intamin also makes a mega-lite coaster, which is like a miniature version of the mega coasters with a first drop of 98 feet (30 meters) at 56 miles (90 kilometers) per hour [source: Intamin]. Mega-lites, with their many high-speed turns at or near ground level, followed by twisting up and downs and ending with a series of hills affectionately called "camel backs" and "bunny hops," are not as high or as fast as the megas and gigas, but they still have their share of thrills.

Wherever you may live, you're bound to have a mega or giga coaster near you. These towering instruments of entertainment (or torture, depending on your point of view) can be found anywhere from Jackson, N.J., to Germany and Japan.
