We run this route through the dry season, and the same conversations come up at the trailhead every time.
So here they are in advance. Nine things worth knowing before you stand at 4,300 metres looking at a fortress built into a pair of stone horns.
1. Give Cusco two days first
This is the one that matters most, and it is the easiest to get wrong.
Waqrapukara is sold as a day tour. A day tour sounds like something you slot in on arrival. Altitude has no interest in what the itinerary is called.
Cusco sits at 3,400 metres. The site sits at 4,300. Two full days in the city before you come, and three if your trip allows it. If you have already done a high day trip and felt fine, that is the best signal you will get.
2. Pace decides your day, not fitness
The travellers who struggle here are rarely the unfit ones. They are the ones trying to keep up with somebody stronger in the group.
Walk at a speed that lets you talk. Take short steps on the rises. Stop before you need to rather than after.
Going slowly at 4,300 metres is not falling behind. It is the correct way to walk up there, and our guides set the pace by whoever is finding it hardest.
3. Eat properly at the low stop
Breakfast happens well below the trailhead, and it is a buffet for a reason.
Food taken at a comfortable altitude does more for you than anything you can manage higher up. Appetite drops as you climb, so the meal you eat at the bottom is the one your body actually uses.
Lunch comes after the walk, not during it. Plan for that.
4. Three climates in one day, so bring layers
Cold at dawn. Strong sun by mid morning. Wind on the exposed ground near the top.
A breathable base layer, something warm over it, and a windproof shell will cover all three. You will use every one of them and you will change at least twice.
Sunglasses, sun cream and a hat are not optional at this height. The sun at 4,300 metres burns in a way that catches people out on cloudy days too.
5. Grip matters more than boots
You do not need mountaineering boots. You do need soles that hold on loose ground.
The descent is where footwear earns its place. Trail shoes with real tread beat stiff boots you bought last week and have never worn.
Whatever you bring, it should already be broken in. The trail to Waqrapukara is not where you test new footwear.
6. Take the poles
They come with our trips and they sit unused in a lot of hands.
Use them. On the way up they give your arms something to do and take load off your legs. On the way down they save your knees on the loose sections. They are the single cheapest improvement to how you feel at the end of the day.
7. Bring cash, even though there is no entrance fee
Waqrapukara currently has no entrance ticket, which surprises people who have priced up Rainbow Mountain or the Sacred Valley.
You still want small notes in soles. Drinks, toilets in the villages, tips for your guide and driver. Nothing on this route takes a card, and there is no machine once you leave the main road.
Forty soles covers a comfortable day.
8. Stay off the walls and back from the edges
Waqrapukara was declared National Cultural Heritage by Peru’s Ministry of Culture in 2017. It is an archaeological landscape in Acos, Acomayo province, not a viewpoint with a fence.
Stay on the paths that exist. Do not climb the structures or move stones. The terraces below the horns are original and they are fragile.
The drop beside the site is real and the wind up there is stronger than it looks from the path. Keep your distance from the edge, particularly if you are lining up a photograph.
9. Weather can change the plan, and that is fine
Rain turns the last stretch of road slow and the trail slick. Cloud can sit on the horns for hours and take the view with it.
If conditions look poor we will tell you honestly, and we would rather move your date than send you up for nothing. Postponing is not a failed trip. It is how a route like this gets run properly.
The short version
Two days of acclimatisation, a slow pace, layers, grip and cash. Everything else is detail.
Waqrapukara asks for a reasonable level of fitness and no technical skill whatsoever. Come with the altitude respected and it is one of the best days out of Cusco. Come the morning after your flight lands and it will not be.
Curious about the site rather than the walk? We ask whether it was ever a fortress in this piece on its history.
