I think the ultimate adventure would be to travel to Space. I would love that to see the earth from the outside surrounded by the darkness of space. But seeing as I'm unlikely to ever have enough money to take off my earthly goals will have to do.
Not a huge climber but I would like to climb a mountain (Mt Kosciusko doesn't really count in my book).

Definately sail around the world but that will have to wait until I move to somewhere remotely close to the coast to learn how to sail.

Walk the Kakoda Track

Go to the Antarctica

Travel around the world without flying.

Cross the Sahara on a camel

There are more and they change regularly

And if ever a discount space airline sets its self up then I'm there.

Man, you guys are giving me so many ideas... this is a TERRIBLE thread to read just before having to slouch off to my 2 pm lecture... sigh.

Someday!

I already have part of my ultimate adventure planned! Instead of RTW, I want to do an overland RTA (Round the Asia!). Or a Bisect The Asia. Not sure what you'd call it.

I'd start in Beijing, take the choo-choo train to Mongolia, cross in the West to Kazakhstan then down to Kyrgyzstan, then into China and take the Western Route into Tibet. From there, overland through Nepal and down into India. I figure to end up on a beach in Goa four to five months after starting.

Spring 2011 ... if anyone is game ...

To ride my bike around the world. I'll be taking off in June to ride from Alaska to Argentina with my husband and kids - so we'll do half of the journey there. If all goes well, we will seriously consider continuing on - flying to South Africa and cycling back north. That way we would go around the world north to south and back north again. Not the direction most people think of cycling around the world, but what the hey!

Mine is kind of boring compared to all the ones that are on here. I'm afraid of heights, so the whole climbing Mt Everest thing is out...although i can't imagine how amazing that would be to stand on top of that mountain...feeling you conqured the world!

I honestly would buy a nice sailboat...and just sail around the caribbean for a few months - listening to Bob Marley and Jimmy Buffett...kind of boring, i know...

Sailing is still an adventure, one I would dearly love to do sometime.

I've got a new one:

Hike the American Discovery Trail end to end. Delaware to California.

I start cycling around South America 2 Mondays from now.

(i use around loosely.. through and around really)

Oneday id like to get into adventure racing, and..

Hopefully sailing sometime once i return home.

The ULTIMATE adventure?

1. I wanna drive all around my country Australia. And stand at the very tip where the sign says, "You are standing on the northern most point of the Australian mainland."
2. Camel riding along the beach at Broome
3. Backpack through Asia
4. Walk along the Great Wall of China
6. See Machu Picchu
5. Learn to ski
7. Climb the Matterhorn
8. Go to Marrakech and go on a camel safari
9. Go to the top of the Empire State Building
10. Visit every country in the world

Since I'm in New Zealand for a year and I love hiking/camping/scenery/etc, I've set a goal for myself to complete all nine Great Walks by the time I go home to Canada.
