If you've always dreamt of diving down to 20,000 leagues under the sea, then news of Virgin's new "underwater plane" will be music to your ears, though perhaps not to your wallet.

The Necker Nymph, Virgin Limited Edition's DeepFlight three-person aero-submarine (what a mouthful...), is an open cockpit winged sub that will take tourists down to the ocean floor on an underwater flight to explore shipwrecks, swim side-by-side with dolphins, or cruise along with whales. Needless to say, it is the first of its kind on the market.

Capable of diving down to depths of 36,000 feet Necker Nymph has the flexibility to glide peacefully over reefs or up the excitement ante with 360 degree turns. The open cockpits afford near ideal 360 degree viewing for passengers, creating a uniquely open experience. Dives can last up to two hours.

Like all DeepFlight subs, Necker Nymph has near-zero environmental impact: it won't land on precious reefs and has low light and noise emissions to keep ocean ecosystems from being disturbed.

Necker Nymph is available either when chartering Necker Belle, Virgin's luxury 105 foot catamaran (weekly charter costs U.S. $88,000), or when staying on Richard Branson's Necker Island. When taking Necker Belle for 7-nights' exclusive hire, the sub is available at an additional weekly rate of US$ 25,000.

I've been racking my brain about how I can cobble together £6,285 by the 25th February 2010. You see, if I can do it I'll be climbing Morocco's Mount Toubkal with wild man Bear Grylls.

I might be biased as my girlfriends and I are slightly in love with Bear, but this mountain experience from bespoke travel agency Black Tomato really is worth shouting from the top of Toubkal about.

Starting at Tigmi, a luxury boutique hotel just outside Marrakesh at the base of the Atlas Mountains, you'll be whisked to Toubkal's base camp by helicopter, where Bear Grylls will meet you. During a four hour trek to the peak of Mount Toubkal (4,167 metres) Bear will wow you with his survival stories. You get to see the man vs. the wild first hand during the trek back to HQ as Bear demonstrates how to fend for yourself in the great outdoors. After all that excitement you head back to Tigmi to relax for the rest of the weekend.

You don't need to be a hardcore mountain climber to qualify just of reasonable fitness as, according to Black Tomato, the Toubkal summit is "an uphill trek rather than a ropes-and-pulleys vertical climb, so the only equipment you'll be using (apart from snow-proof clothing) will be crampons and your very own muscle power."

The icing on the cake is that you can travel with your other half without them having to come on the hike too; those who prefer a bit of pampering with their panoramic mountain views can tag along on a three-day spa package.

Right, I'm off to begin the hunt for spare change.
