Puerto Vallarta

If your idea of adventure involves flinging yourself off sturdy platforms deep in the Mexican jungle, hurtling above treetops at speeds intended more for migrating hawks than humans, then the Zip Line Adventure at Canopy River should rocket straight to the top of your shortlist. Nestled just a half-hour trek from Centro, this adrenaline-packed escapade lets you swoop over the dense, monkey-haunted foliage and jagged ravines of the Sierra Madre mountains, a region rugged enough to have once kept conquistadors nervously polishing their helmets at sea level. Go early-when the morning mist still hangs romantically between trees, offering prime lighting for your inevitable panicked selfies-and book a couple days in advance to dodge the tour-bus armies. Budget $60 to $85 USD per person, because safety harnesses and trained guides who don't laugh too loudly when you scream don't come cheap. Sunglasses, bug spray, closed-toe shoes, and a solid sense of humor are essentials; dignity, however, is entirely optional. Ultimately, even if you lose your composure (and possibly your dignity) during the initial leap, the sheer rush-and the bragging rights about careening Tarzan-style through jungle canopies-make this an affair well worth the existential panic.

Let's face it-there are precious few moments in life when huddling on a boat at the crack of dawn, clutching your camera in watery-eyed anticipation, seems rational. Whale watching in Banderas Bay, however, is emphatically one of those times. From December to March, these aquatic giants migrate thousands of miles to splash and serenade off the coast near Centro, transforming an ordinary Mexican morning into a Discovery Channel special with margaritas on standby. Book at least a couple of weeks ahead-no one likes being stuck on shore, mentally cursing the organized tourists who nabbed the last seat-and budget around $80 to $120 USD, depending on your tolerance for frills and your fondness for free drinks. Bring sunscreen, binoculars, and your most convincing impression of Captain Ahab, just in case the whales aren't cooperating. Above all, do it because there's something deliciously surreal about chasing thirty-ton mammals, creatures so majestic yet indifferent to humanity, that you'll gladly endure the inevitable cheesy whale puns from your tour guide-if only for the chance to look your jaded friends in the eye and casually say, "Oh, did I not mention the time I danced with humpbacks in Mexico?"
