I realize that I keep getting requests for information from friends -- so why not just share my trip with the tripadvisor community, rather than typing over and over again! Thus this is a long overdue trip report for my post-bar trip to Peru. This was the second half of my trip - I actually started in Equador and went to the Galapagos first. (you can check that forum for my trip report also).
This is about my stay in Cusco and hiking the Inca Trail.
Adjusting to Cusco: I really liked Cusco - it's very charming! You might need to plan for a few days beforehand though, to adjust to the altitude. I didn't find it necessary to take altitude sickness pills, but one of my friends started taking it before we got there and she thought it helped her. Another one of my friends got sick while there (she was throwing up) but there are plenty of pills you can buy while there (she got the ones called Soroachi).
Altitude sickness is like having a hangover, I think - headaches, with some dizziness. Drinking coca tea definitely helped me. I advise dumping a lot of sugar in it though, unless you really like drinking leafy-tasting beverages.
Places to Stay in Cusco: We stayed at the Hotel Rumi Punku while there. It is located in a really good area very close to the square. You can find cheaper lodgings, but I'd advise you to be careful about what part of the city it's in. Ours was very safe, and they posted a guard outside at night. Also, the door had a buzzer and lock on it at all times. It was also very clean and there was a very good complimentary breakfast. So we chose that for those reasons.
I personally am not that paranoid about my personal safety when I travel (probably dumb) but if you are, Rumi Punku is a good bet. It ran $105/night for 3 people when I stayed there this past September. This would be on the pricey side of things... I think. We'd actually booked at a cheaper hotel for when we returned from the hike, but we fell in love with the Rumi Punku so decided to switch and stay with them!
Things to Eat in Cusco: I loved the restaurant inside the Precolombino museum - it's called the MAP Cafe, and it is this tiny restaurant encased in a glass box inside the courtyard of the museum. We went there twice and loved it both times. Their pork belly was really good, the desserts were delicious, and they have very good wines. It's pricey for Peru, but I think it's well worth the price given the value. I think it'll come out to about $20-30 per person...? Not positive. We also went to the very fancy restaurant, Restaurante Illary, (where I tried alpaca for the first time) which was nice, especially for ambience, but I liked the food at MAP better.
For more casual fare, you should eat pizza in Cusco because they use really good brick ovens to make a crispy chewy crust. I ate at Chez Maggy (they have multiple locations throughout the city) and I thought it was quite good. Also, if you or your travel mates are adventurous, you should consider trying alpaca, guinea pig (called "cuy" - a delicacy there), and chicharron - fried pork.
Sightseeing in and around Cusco: You absolutely have to do the Sacred Valley loop. There're some ruins right outside Cusco - of these, I think Sacsayhuaman is a must-see. I loved that site a lot. I think it was my favorite. I think key sites to see in the Sacred Valley are Ollantaytambo and Chinchero, with Pisac, Tipon, Moray and Maras being optional but highly recommended.
IMHO, you should get a private driver (we asked our hotel to recommend one), because the buses are extremely commercial and they end up driving you to markets and restaurants instead of the actual sites. The ruins are also quite spread apart, so if you go on your own you avoid crowds and you see a lot more.
Other than that, just talk a walk around the city square and some of the small narrow streets. The foundations - the roads - are amazing!! The twelve sided stone is huuuge. It's hard to believe that this stuff has been put together without any mortar or cement. You can also really tell the difference between the original and the later structures. I also went to the Temple of Q'oricancha, but actually didn't find it that impressive.
Hiking the Inca Trail: this was really fun, although for some people it seemed more arduous and painful than fun or relaxing! It can be a hard climb, especially the second day (it is called the Dead Woman's pass for a reason...j/k. All the tour guides say that it is called this because of the shape of the mountain - but most hikers will tell you it is because you climb endless, endless steps - only to descend them all again) and especially if you have altitude sickness.
Speaking of that - most tour groups will require you to pay the remaining balance on your trip in person at their office at least two days before your trip departure. This is their way of ensuring that you are there long enough to acclimate to the altitude. So figure that into your planning!
I really recommend going with a reputable tour agency. They provide better tour guides who speak English (I guess this isn't a concern if you speak Spanish) and they treat their porters well. After arduous research I went with Llama Path, but I also looked into United Mice, Pachamama Explorers, and Andean Adventures. Obviously I can't speak for the others, but I really have nothing but praise and rave reviews for Llama Path. They were clean, orderly, had brand new tents, good food. The porters were amazing, and outfitted and equipped well. (They made us a cake our last night!!) Our tour guide was really great - taught us so much not only about the history and symbolism of the sites, but also about nature. He collected mint leaves on our way, and we had fresh brewed mint tea in our tents after dinner. Delicious!
We got to the actual Machu Picchu site pretty late on our hike, so there was no time to hike Huayna Picchu, which was too bad because we'd heard about just how amazing the view is from up there. If you have the chance, you should probably hike up there!
Finally, hikes of the Inca are permit only (limited to 500 per day) so I think you're best off booking early, especially if you're going during peak season (which I think is June through Sept. The trail is closed in Feb). But i've heard that other hikes, like the Lares, are really pretty too.
