Extraordinary activities to do while on vacation....

My top three activities that I have yet to do on a vacation is swimming with dolphins, parasailing, and snorkeling. I'm most excited to swim with dolphins. I think that is soooo becoming one with nature! I'm most scared to parasail but would definitely want to try. I seen a video of a couple parasailing and the attachment to the boat broke sending them falling into the ocean. Talk about a HEART ATTACK! Even with a little fear, I will conquer parasailing. My last but not least activity on my list to do is snorkeling. I don't want to just snorkel anywhere.... I will leave this adventure for my trip to Australia's Great Barrier Reef. Snorkeling at it's ultimate BEST!! What are your wildest activities to do on vacation?
