Ilha Grande

If your idea of travel bliss involves scrambling uphill at dawn, dodging slippery roots, and privately cursing whoever invented the phrase "almost there," then hiking Pico do Papagaio on Ilha Grande is your ticket to nirvana-or at least an amusingly strenuous hell. Rising dramatically above the lush rainforests of Abraao, this natural landmark-aptly dubbed "Parrot Peak" thanks to its uncanny resemblance to a slightly smug tropical bird-offers a payoff worth all the perspiration: a dramatic panoramic vista of emerald islands floating in turquoise seas. Set your alarm for an ungodly hour (think 3 AM) to beat the oppressive midday heat and catch an absurdly pretty sunrise. Pack a sturdy flashlight, insect repellent strong enough to deter Jurassic-era bugs, and plenty of water to keep existential dread at bay. Budget-wise, setting aside $15-20 for a local guide isn't just encouraged, it's practically mandatory-unless you're fond of spending your vacation wandering lost in dense jungle foliage. Sure, your knees will hate you, and yes, you'll discover muscles you didn't even realize existed. But trust me, when you're back down sipping a cold cerveja and boasting to fellow travelers about conquering that jagged beak-shaped peak, you'll know exactly why it was worth every slippery, sweaty step.

Sea turtle watching at Lagoa Verde is a bit like stumbling into a marine-themed speakeasy-quiet, enchanting, and frequented by shelled guests who glide in and out with enviable nonchalance. These ancient reptiles have been cruising Earth's oceans since before T-Rex scribbled extinction into its planner, and seeing their sleepy-eyed majesty drifting serenely through clear turquoise waters feels genuinely humbling (and a touch surreal, especially if you're nursing last night's caipirinhas). Dawn or late afternoon offers prime viewing-the turtles prefer cocktail hours-and planning a day or two ahead is sufficient to avoid the buzz-killing crowds. Budget about 40 to 60 reais for snorkel rental and a friendly local guide whose salty tales alone make the price worthwhile. Bring sunscreen, patience, modest swimwear (lest you scandalize the turtles), and perhaps a waterproof camera-Instagram needs more turtle selfies. Even if wildlife isn't typically your scene, Lagoa Verde turtle spotting is worth the price of admission just so you can casually mention over dinner back home how you spent your vacation casually swimming alongside creatures older than civilization itself.

Snorkeling in Lagoa Azul's absurdly clear waters is one of those outings that'll make you question your life choices-specifically why you ever willingly spent afternoons wedged between sweaty tourists in dusty museums, when all along you could've been hovering serenely above psychedelic fish, sparkling reefs, and underwater landscapes that look suspiciously Photoshopped in real life. Historically, the Blue Lagoon has drawn everyone from Portuguese explorers seeking paradise (and conveniently forgetting their maps) to globetrotting nomads chasing postcard-perfect selfies. Go early-I'm talking first-cup-of-coffee early-because by midday, the once-pristine lagoon threatens to become a crowded fish tank of flailing fins and neon pool noodles. Booking a couple of days in advance will save you from frantic last-minute haggling; and for around $50-$70 USD per head, you'll score your snorkel gear plus the dubious bragging rights of wearing a soggy life jacket worn before by who knows how many excited travelers. Bring sunscreen, obviously, but also pack a dash of skepticism toward your guide's assurances that those gentle swirls beneath you are "definitely turtles, not sharks." Even if snorkeling isn't your usual cup of caipirinha, do it anyway-because bobbing contemplatively in Brazil's warm, blue embrace is exactly the sort of memory you'll smugly trot out at dinner parties until your friends quietly resent you.

Pitching a tent beneath the stars in Aracatiba feels like stumbling onto Ilha Grande's best-kept secret-if secrets involved mosquito bites and questionable decisions about comfort. But squatting in the sand and feeling deliciously insignificant under a cosmic swirl sends you back to the raw, minimalistic appeal of travel before Instagram and Wi-Fi ruined it all. Located on the island's quieter northern coast, Aracatiba is the laid-back cousin your parents warned you about, a tucked-away haven once frequented by pirates hiding from Portuguese patrols and now home to backpackers escaping Rio's glitz and gentrification. Show up mid-afternoon for prime campsite real estate, packing essentials like insect repellent strong enough to dissolve plastic, a headlamp that'll prevent unfortunate midnight stumbles, and, naturally, a flask of your favorite Brazilian cachaca for courage and fire-starting assistance. Budget-wise, camping here is refreshingly affordable; depositing around $10 to $20 a night for a patch of paradise won't break even the most precariously-balanced backpacking budget. And while Aracatiba might not offer five-star amenities, rest assured the friendly locals and epic, star-spangled skies make up for the occasional midnight critter encounter. Because years later, long after you've scratched that mysterious bite and sand still mysteriously trickles out of your bag, you'll tell friends that yes, you spent a night under the Brazilian stars-and you'll mean it, even if you conveniently forget the parts involving bugs and regret.
