You're getting hitched! Good for you and good luck to her, or him. Naturally , the end of bachelorhood must be celebrated with a guys trip unlike any other, and no cliché Vegas trip is going to cut it.

From helicopter pub crawling in Australia to white water rafting across the Colorado River, here are some unusual (but memorable) picks for an ultimate boys weekend.

Thank us later.

1. Skydiving in Honolulu

The sky's the limit, so why not cross off this bucket-list staple? For adrenaline junkies, free falling through Hawaii's skies with an amazing bird's eye view of the island is the perfect way to go all out before tying the knot. Book it: Groups of four to nine people can get a discount price of $140 per person with Skydive Hawaii. Whether you're an expert skydiver or looking to take the plunge for the first time, this is one experience on which you and your crew won't want to miss out.

2. Helicopter pub crawling in Sydney

Book it: Sydney Helicopters tours start at $995 per person,

Odds are you've experienced a few pub crawls, but we're betting you haven't experienced a heli-pub tour. Instead of stumbling from bar to bar, you and your mates can hop into a chopper for a full day of touring Aussie pubs and epic sightseeing. Top off the stag trip Down Under by stopping by Manly Beach, one of Australia's famous surfing beaches, to recuperate and catch a miraculous sunset view.

3. White water rafting on the Colorado River

Book it: A 6-hour full day rafting trip is $88 per person, group discounts available, at Colorado Whitewater Rafting

Go off the beaten path by spending an outdoorsy weekend white water rafting through the Colorado River. There's no better way to experience the real meaning of teamwork than to raft through the river's most powerful rapids with your closest friends. If you decide to go in winter, forget rafting and bring your skiis instead. And if your group is craving a night out on the town, head on over to the bars in Denver to get a party fix.

4. Scuba diving in Cancun

Book it: Scuba Diving Cancun starts at $85 per person (including bilingual guide, dive equipment and two reef dives).

Cancun's many adventures are often overlooked because of the locale's rep as a spring break party destination, but it's also home to several dive sites and reefs packed with marine life. For dive enthusiasts and thrill seekers, an underwater bachelor party is a must. Not certified? No worries. Several scuba sites in the area offer classes for beginners. Toss in some tequila and head out to Coco Bongo at night, and you've got yourself one hell of a man-bash.

5. Kayaking in the Galapagos

6. Golfing in Hilton Head Island

8. Paragliding in Rio de Janeiro

Book it: Rio Hang Gliding starts at $169 per person.

Step out of your comfort zone and reward yourself (and your guys) with an unforgettable hang gliding excursion. The panoramic views of the city's mountains, beaches and forest are a must-see. Rio is a great option if you're looking for both an adventure and a tropical getaway, offering prime parties into the wee hours. If paragliding isn't your thing, Rio offers a wide variety of other water sports, delicious food, beautiful architecture and museums worth checking out. A trip here isn't complete without a visit to Ipanema Beach, which is consistently ranked as one of the world's sexiest beaches .
