• most people love a great view and this is a major component of why hiking at high altitude is popular
• many also love the challenge of the usually strenuous hikes which involve a lot of ascent and descent
• the very high altitude treks above 3000m such as Annapurna and Mt Kilimanjaro also add the issue of need to acclimatise and risk of high altitude sickness

• most of these are at a fairly “modest” 1200m elevation
• the highest in Australia is the Mount Kosciuszko summit walk in NSW at 2228m
• these can be deceptively more dangerous than ultra high altitude tourist hikes (eg. Annapurna) as:
  • you generally do not have a guide
    • you have to be self-sufficient with navigation tools (including map and compass don't rely solely on your phone!), emergency SOS capability
  • you will not have someone to carry your gear
  • you tend to be frequently below the tree-line and easier to get profoundly lost
    • the hiking paths can be overgrown and hard to follow and very easy to get lost amongst the forested parts below the tree-line
  • there are no tea houses (although some do have huts)
    • you have to BYO tent
    • you have to BYO food, cooking gear and water
    • for multi-day hikes, may need to place secured food drops yourself along the way via car or other means
    • you will need to BYO a method of managing toileting waste (eg. shovel or plastic bags or tubes to bring it back home with you)
    • you will need to BYO hand cleaning method for after toileting
    • you will need to bring water sterilisation option and enough fuel for your cooking needs
  • it often rains and blizzards can happen unpredictably any time of year
    • hiking in cold wet conditions requires a very different approach to hiking in dry snow conditions
    • if you get wet, you will die from hypothermia quickly once you stop moving unless you can get yourself dry quickly and getting wet can be from your own perspiration or your shelter being compromised - there are no tea houses to dry off in!
    • you should bring a strong hiking umbrella and a method of lighting an emergency wood fire
  • many of these are very remote from civilisation or other hikers and help may take many hours even if you have a SOS beacon
    • if you are silly enough not to have a reliable method with which to call for help, or, you fall and cannot call for help, it may take many days or weeks before anyone finds you
    • you can be in major trouble if you injure your ankle or step on a snake and get bitten (because you are not wearing boots and thick gaiters)
  • in Winter, most alpine roads are closed to vehicles
  • all this means a much heavier back pack you have to carry

• risk of high altitude sickness caused by rapid exposure to low amounts of oxygen at elevations above 2000m but more commonly above 2700m (due to falling air pressures) without adequate acclimatisation
  • may cause headaches, vomiting, tiredness, confusion, trouble sleeping, and dizziness usually with 10 hours of the ascent
  • being physically fit does not decrease the risk
  • prevention:
    • gradually increasing elevation by no more than 300 metres per day when above 2000m
    • avoid strenuous activity such as skiing, hiking, etc. in the first 24 hours at high altitude
    • avoid alcohol or sedatives as they slow down the acclimatization process
    • drink adequate fluids as dehydration also can cause headaches and increase risks of HAR
  • occurs in 20% of people after rapidly going to 2,500 metres and in 40% of people after going to 3,000 metres
  • mild cases may be helped by ibuprofen, acetazolamide, or dexamethasone
  • severe cases require immediate descent as they may progress to life threatening or disabling conditions:
    • high-altitude pulmonary oedema (HAPE)
    • high-altitude cerebral oedema (HACE)
    • high-altitude retinopathy (HAR) causing blindness which can last weeks although can be asymptomatic - usually when over 3600m but can occur lower if dehydrated or have high altitude polycythemia
  • long term exposure may cause chronic mountain sickness
