Inca Trail

I would like to express my deepest and most sincere gratitude to Sap Adventures for an amazing and unforgettable trek along the Inca Trail. From the first email before our trip until our departure from Cusco, everyone at SAP took excellent care of my mom, my aunt, and me, but I especially want to thank our guides: Braulio and Franklin. We literally would not have made it to Machu Picchu without them.
We knew going into the trek that we would be the slowest of the group, but we were unprepared for the altitude sickness and exhaustion. After the first half hour of hiking, we only saw the rest of the group and Braulio at a few rest stops, meals, and in the evenings. When we did see Braulio, he was a wonderful guide; very knowledgeable, outgoing, friendly, and concerned for our well being. At Machu Picchu especially, he demonstrated an extensive archaeological understanding, and my only regret is that we were not fast enough to spend more time with him and the rest of the group. Franclin stuck with us at the back for the entire trek, and I sincerely believe that it was only his patience, encouragement, and care that got us to Machu Picchu.
Beginning on the first day, my aunt unfortunately had a hard time and struggled with altitude sickness and exhaustion. As would become our trend, darkness fell before we reached camp, and we needed to stop every few feet to take a break. But Franclin, who had been with us all day, kept up his enthusiasm and encouragement. Braulio and several porters, despite having already reached camp and seen to the needs of the rest of the group, returned to us for the last part of the trek to light our path and help us for the rest of the way to camp. Once there, they administered oxygen to my aunt and made sure we were as comfortable as possible.
At the beginning of the second day we were amused to see that we had been assigned our own personal porter, Mario, who quietly shadowed us like a guardian angel for all of the second and third days just in case we needed more help. Despite having to take care of three rather slow hikers, Felipe and Mario never complained. I cannot possibly express my appreciation enough. Felipe treated my mom and aunt as if they were his own much-loved and respected mother and aunt, and helped keep my worry for them at bay by pointing out orchids, describing the Inca ruins, and trying to teach me Quechua.
In addition to Felipe, Braulio, and Mario, the other Sap Adventures porters, cooks, and coordinator all helped make the trip amazing.

Altitude Sickness

Altitude sickness is also an experience... don't ever panic! :

Get High...feel fine!
How to beat altitude sickness


No hurling. You can prevent or diminish altitude sickness -which typically occurs above 8000 feet- if you follow this advice:


Rest Up. Get at least two 8 hours nights of sleep, and make sure you are well hydrated before you start; you can also acclimatize by spending 3 days at high altitude.
Don't race, climb slower than your normal walking pace. If you need to rest after ascending only 20 yards, your are flirting with exhaustion and need to dial it back.


Dig deeper. When your legs turn to stone or you feel nauseous, we suggest presure breathing: 'Take a deep breath, then force air out through pursed lips like you're blowing out a candle. Do this 3 to 4 times a minute; vigorous respiration pushes more oxygen from the lungs into the bloodstream.


Hit the bottle. Some studies show that the herbal remedy COCA tea (inca leaf tea) helps increase red blood cells (drink it a lot)
Some drugs that contain acetazolamide (such a Diamox) can prevent or alliviate some forms of altitude sickness but be aware if side effects such as numbness and frequent urination. See a doctor for prescription and dosage information.
Treat early Altitude sickness typically starts with nausea, lethargy, headache, irritability. and/or loss of appetite.We suggest immediate action: slow your pace, hydrate, practice presure breathing - or just take a rest. If your condition doesn't improve, there's one simple, surefire solution-descend.


 Facts and advice: 

What is meant by high altitude? Some "formal" medical definitions:

  • High Altitude: 1500 - 3500 m (5000 - 11500 ft)
  • Very High Altitude: 3500 - 5500 m (11500 – 18000 ft)
  • Extreme Altitude: above 5500 m

Practically speaking, however, we generally don't worry much about elevations below 2500 m (8000 ft) since altitude illness rarely occurs lower than this. Acclimatization is the process of the body adjusting to the decreasing availability of oxygen- by increasing the amount of red bloods cells-. It is a slow process, taking place over a period of days or even weeks.

Physiologic changes due to altitude:

  • Changed breathing pattern at night 
  • Awakening frequently at night
  • Weird dreams
  • Hyperventilation (breathing fast)
  • Shortness of breath during exertion
  • Increased urination

Types Of Altitude Sickness

Acute Mountain Sickness (AMS) 
This is the most common of all types of altitude sickness. When acclimatization lags significantly behind ascent, various symptoms occur. Acute Mountain Sickness (AMS) represents the body's intolerance of the hypoxic (low oxygen) environment at one's current elevation. 

Who can get AMS? Anyone who goes to altitude. It is primarily related to rate of ascent. No way has been found to predict who is likely to get sick at altitude.

Mountain rule 1 
  • It is OK to get altitude illness. It is not OK to die from it.


Don't violate this rule! Anybody can get AMS , there is no prevalence based on age, gender, physical fitness, or previous altitude experience. If you know what to do you should be able to avoid the severe, life-threatening forms.

Mountain rule 2
  • Any illness at altitude is altitude illness until proven otherwise .


 Recognizing AMS . I n the context of a recent ascent, a headache , with any one or more of the following s ymptoms above 2500 meters (8000 feet) qualifies you for the diagnosis of AMS:

  • Loss of appetite, nausea, or vomiting
  • Fatigue or weakness
  • Dizziness or light-headedness 
  • Ear ringing
  • Difficulty sleeping, insomnia
  • Confusion, hallucinations
  • Staggering gait

It is remarkable how many people mistakenly believe that a headache at altitude is "normal" when it is actually AMS. Be willing to admit that you have altitude illness . 

How to Avoid AMS 
The key to avoiding AMS is a rational ascent that gives your body time to acclimatize. People acclimatize at different rates, so no absolute statements are possible, but in general, the following recommendations will keep most people from getting AMS: 

At altitudes above 3000 meters (10,000 feet), your sleeping elevation should not increase more than 500 meters (1500 feet) per night, and every 1000 meters (3000 feet) you should spend a second night at the same elevation.

SAP Adventures strongly recommends you spending 3 to 4 nights at a high elevation city above 3000 meters in order to minimize the possible effects of theAMS specially before undertaking the Inca Trail to Machu Picchu or any other Andean trek in/around Cusco.

What To Do If You Have AMS

Mountain rule 3
  • Never ascend with symptoms of AMS. 
  • It is always OK to descend, you will get better faster.


Severe Types of Altitude Sickness

High Altitude Cerebral Edema (HACE) 

AMS is a spectrum of illness, from mild to life-threatening. At the "severely ill" end of this spectrum is High Altitude Cerebral Edema; this is when the brain swells and ceases to function properly. Obviously, this is a Bad Thing to have happen to you. 

HACE, once present, can progress rapidly, and can be fatal in a matter of a few hours. Persons with this illness are often confused, and may not recognize that they are ill. 

The main symptom of HACE is a change in the ability to think. There may be confusion, hallucinations, changes in behavior, or lethargy. However, it is probably easier to recognize a characteristic loss of coordination that is called ataxia . This is a staggering walk that is identical to the way a person walks when very intoxicated on alcohol. 

To test for this abnormal walk, have the sick person do a straight line walk (in medical speak this is called the "tandem gait test"). Be fair: do this on level ground, take off their backpack, and don't have them try it in big heavy boots. Draw a straight line on the ground, or have them follow a crack in the teahouse floor. Have them walk along the line, placing one foot immediately in front of the other, so that the heel of the forward foot is right in front of the toes behind. Try this yourself. You should be able to do it without difficulty. If they struggle to stay on the line (the high-wire balancing act), can't stay on it, or fall down, they fail the test and should be presumed to have HACE . 

The treatment is immediate descent . This is of the utmost urgency, and cannot wait until morning (unfortunately, HACE often strikes at night). Delay may be fatal. The moment this is recognized is the moment to start organizing flashlights, helpers, porters, whatever is necessary to get this person down. How far down? At least to the last elevation at which they woke up in the morning with no symptoms of AMS. Bearing in mind that the vast majority of cases of HACE occur in persons who ascend with symptoms of AMS, this is likely to be the elevation the person slept at two nights previous. If you are uncertain, 500-1000 meters descent is a good starting point. 

People with HACE usually survive if they descend soon enough and far enough, and usually recover completely. The staggering gait may persist for days after descent. If recovery has been complete, and there are no symptoms, cautious re-ascent is acceptable. 

High Altitude Pulmonary Edema (HAPE) 

Another form of severe altitude illness is High Altitude Pulmonary Edema, or fluid in the lungs. Though it often occurs with AMS, it is not felt to be related and the classic signs of AMS may be absent. Symptoms of HAPE include any of the following:

  • Extreme fatigue
  • Breathlessness at rest
  • Dizziness or light-headedness 
  • Cough, possibly productive of frothy or pink sputum  
  • Gurgling or rattling breaths
  • Chest tightness, fullness, or congestion 
  • Blue or gray lips or fingernails

The treatment for HAPE is the same as for HACE: immediate descent . As with HACE, it is of the utmost urgency; delay may be fatal . The same rules apply for how far as well: to the last elevation where the victim felt well upon awakening. 

Whereas HACE descent is complicated by confusion and staggering on the part of the victim, HAPE descent is complicated by extreme fatigue and possibly also due to confusion (due to inability to get enough oxygen to the brain). HAPE frequently occurs at night, and may worsen with exertion. 

HAPE resolves rapidly with descent, and one or two days of rest at a lower elevation may be adequate for complete recovery. As with AMS, once the symptoms have fully resolved, cautious re-ascent is acceptable. 

It is common for persons with severe HAPE to then also develop HACE due to the extremely low levels of oxygen in their blood (equivalent to a continued rapid ascent).

Mountain rule 4
  • If you are getting worse, go down at once.


Do Not Wait Until Morning. Descend at least to the elevation where you last felt well when you woke up.

Mountain rule 5
  • Never leave someone with AMS alone.


People sick with AMS can get worse, and may need help descending, or may not recognize that they are getting sicker. 

Things to Avoid 

Respiratory depression (the slowing down of breathing) can be caused by various medications, and may be a problem at altitude. The following medications can do this, and should never be used by someone who has symptoms of altitude illness (these may be safe in non-ill persons, although this remains controversial):

  • Alcohol
  • Sleeping pills (acetazolamide is the sleeping tablet of choice at altitude) 
  • Narcotic pain medications in more than modest doses   

How to recognize high altitude headaches: 

Trekkers always wonder about how to tell if a headache is due to altitude. Altitude headaches are usually nasty, persistent, and frequently there are other symptoms of AMS; they tend to be frontal (but may be anywhere), and may worsen with bending over. However, there are other causes of headaches, and you can try a simple diagnostic/therapeutic test. Dehydration is a common cause of headache at altitude. Drink one liter of fluid, and take some acetaminophen or one of the other analgesics listed above. If the headache TOTALLY resolves (and you have no other symptoms of AMS) it is very unlikely to have been due to AMS. 

The main treatment of AMS is rest, fluids, and mild analgesics: acetaminophen (paracetamol), aspirin, or ibuprofen. These medications will not cover up worsening symptoms. Descent is always an option, and recovery will be quite rapid...

Other recommendations to help your body acclimatize are:

  • Avoid over-exerting yourself when you first arrive (however, some gentle activity during the day is better than sleeping)
  • Eat lots of carbohydrates 
  • Drink lots of fluids (water no beer)   
  • Avoid cigarettes and alcohol
  • Avoid taking sleeping pills 
  • Drink coca (ancient traditional leaf) tea
  • Take Diamox (consult your Dr first).
