(A Gringa's Perspective)
Based on the 6 weeks I spent traversing Argentina and Peru last year, I thought I'd share a few bits of advice that I wished I had known prior to embarking. Sometimes it's fun to learn by experience, other times it's expensive and stressful and you just wish someone would have told you. Hopefully this list will find its way to curious Googlers trying to prepare for their trip to South America. By no means do I claim to be an expert on these matters, this is just a bit of wisdom drawn from my experiences traveling from Buenos Aires to El Bolsón, through Bolivia, to Cusco and the Sacred Valley, and finally to Lima and home.
2. If you're the kind of person who enjoys using toilet paper when relieving yourself, always carry some with you when you're out and about. You cannot expect the public bathrooms to have any. I cannot stress this enough. It is possible there will be a woman standing outside the bathroom, selling toilet paper, but she will have already divided it up into amounts she deems sufficient, and it will never be enough. Not ever. So for God's sake, bring your own.
3. When in Argentina, if someone offers you a maté, you take it. Don't worry about the fact that you'll be drinking from the same mug and the same straw as everyone else in the general vicinity. You'll be fine. Drink until the mug is empty (regardless of how unbearably strong it tastes), and pass it back to the person with the thermos. You must drink two separate mug-fulls before you can decline another mug. Do not say "gracias," unless you have already had these two mug-fulls. Saying "gracias" indicates you don't want more. If you haven't yet had your second mug, and you're returning an empty mug, say something to the effect of, "Qué rico", "Me gusta", or just don't say anything at all. Also, if you're at someone's house and they ask you how you take your maté, it doesn't actually matter what you want; tell them you'll take it however they're having it. This is serious stuff, y'all. Don't mess this one up.
4. Before you arrive at any airport or major bus station, do some research to find out what an appropriate price is for a taxi from the airport to wherever you're going. Almost without fail, if you don't know what the going rate is, you will pay twice the amount you should. Act confident (even if you're not), and refuse to pay a rate more than what you know to be fair. If you don't know very much Spanish, at least learn how to have this conversation with a potential driver. Unless of course you enjoy being swindled. (I'm speaking from experience as a person who was swindled out of $80 USD from a taxi driver in Buenos Aires. Live and learn).
5. Unless you're in a major city, don't expect the pharmacy to have anything you need. You think tampons are a basic item? Think again. Out of contact solution? Hope you brought glasses. Have an actual health problem that requires medication? Cross your fingers it's not life-threatening. Fortunately there is often more than one pharmacy in a town, so you may get lucky. Just be prepared to go without.
7. Always carry a decent amount of cash (both US dollars and local currency). This is especially helpful for airport travel, as there will usually be a unexpected baggage fee, exit tax, entry tax, toilet paper fee, fee for speaking broken Spanish, etc. And it will all be cash only. Also, you may have to purchase an unexpected visa for a layover in Bolivia, and they'll only accept US dollars. You don't want to find yourself at the customs counter in Bolivia, without a visa or cash, crying and pleading in broken Spanish to the security guards to let you go to the ATM. Please, learn from my mistakes. Also, be aware of exchange rates, otherwise you might make careless ATM withdrawals and later have a heart attack when you check the status of your bank account.
8. If you're in Peru, I'm assuming you'll be visiting Machu Picchu (as you should). It's best to arrive early in the morning, when the crowds will be more at the Six Flag level and not yet to the Disney World level. When I say early, I mean you'll be waking up at 3:30am (unless you're staying in Aguas Calientes, the town of Machu Picchu. If you're staying in Cusco, it will take you about 4 hours to get there, via taxi, train, and bus). Make sure you bring plenty of water, hearty snacks, and a rain jacket. They sell water and food there, but it's extremely overpriced. Like, the same you would pay for food and water in the States. Outrageous, I say. Also, if you want to climb Huayna Picchu (the steep mountain featured in all the pictures of Machu Picchu), just know you have to make a reservation in advance.
9. If you'll be touring the Sacred Valley in Peru, I highly recommend the town of Pisaq. Go on a Sunday, as there's a huge market with fresh produce, handicrafts, etc. There are ruins up in the hills overlooking the town, and they're definitely worth it to see. You can hike up, but we took a taxi. It was a reasonable price, and the driver will take you up to the ruins and make plans to meet you 2 hours later at the end of the trail. Really convenient. I enjoyed the ruins of Pisaq almost as much as I did Machu Picchu, and what was great was the lack of tourists. It was almost empty! Gorgeous views of the Sacred Valley, great scenic hiking, and lots of various sites to see, including an Inkan cemetery.
10. In the town of Ollantaytambo, there is a restaurant called Hearts Café (Café Corazones), and I highly recommend it. Besides the fact that 100% of its proceeds go to an NGO that teaches life skills to Andean children, the food is out of this world delicious. Lots of vegetarian options, natural food, international cuisines, and it seems almost everything is homemade. The bun for my veggie burger was definitely freshly made, and there were pieces of real tomato in my ketchup. They also serve High Tea, complete with tea, scones, clotted cream, and jam. A real treat to find in a small village in Peru..
11. You'll probably catch on to this one pretty quickly, but when meeting people (friends, host families, etc.), expect to hug and exchange cheek kisses. It's rude if you don't. Even if you're from America and hugging a stranger is a lot to ask, get over it, and kiss the person in front of you. Even if you're a dude, and he's a dude. It's standard procedure and will continue to be every time you see or depart from this person henceforth.
12. If you're staying in Cusco and planning on taking day trips to outlying towns in the Sacred Valley, do not even worry about finding transportation. It's the easiest thing on earth. Let's say you're trying to get to Pisaq. Find out from your hostel or hotel staff where the appropriate combi leaves from, go to this general vicinity, and then stand there for a second looking confused. Almost without fail, a man will yell out to you, "Pisaq?!" and then you nod, and he will lead you to a large, white van. Don't be alarmed; this is a combi. Find your seat. (Mom, I never did this. But if I did....well, nevermind.) Later in the day, when you're in Pisaq and trying to get back to Cusco, it will be even easier. You don't even really have to go to one particular area. Just look vaguely like you might be a tourist, and someone will find you and offer you a ride to Cusco. Buses, combis, taxis -- your options are pretty much endless. Just remember to always agree on the price before agreeing on the ride.
So there you have it. Hopefully this list has been helpful or at least a bit insightful for anyone planning on taking a trip to either of these countries. If you're on the fence about whether or not to go, please go. You will not regret it. Sure there are dishonest taxi drivers, inaccurate bus schedules, and poorly stocked pharmacies. But the incredible experiences you will have will completely trump all the insignificant unpleasant ones. Go, stay as long as you can, and see as much as you can. If your trip is anything like mine, it will always be one of your favorite memories.
