The world is my oyster. Or at least, a little slice of the Cordillera Blanca is. I’m very pleased with my photocopied and laminated 1:100 000 topo – it covers all the quebradas within striking range of Huaraz. Overnight bikepacking galore.

Heading up, up and up towards Quebrada Ishinca.

Traffic: plump sheep tailback.

After a hefty climb, our dirt road dead-ends at a windswept football pitch, from where the trail narrows down in width.

Dreamy riding conditions, give or take the odd push.

Our picnic spot. A perfect spot for contemplating the ills of the world, and how they might be alleviated by the simple act of pedalling.

Case in point: popcorn, apples, bananas and sweet bread keep our legs turning.

Before long, the trail wends its way through a thicket of Quenoal Forest – a tree found only in the high Andes, between 3500-5000m.

It’s a tree known for its gnarled, contorted branches, as well as its distinctive texture. Hence the Latin name. Polylepis: poly – many – letis – layers. It’s this layering effect that helps protect it from low temperatures.

Yum. The delicate, paper-thin bark reminds me of mille-feuille pastry found in French patisseries.

Further up, the trail is a little less rideable – especially given the increasing elevation. But spirits are buoyed: it has all the ingredients of a rip-roaring descent…

I pitch my tent up on the pampas at 4350m, bidding farewell to Ben, who soaks up the view, before turning round and heading for home.

More lung friendly, clean air, as evident by all the lichen splatters on the rocks.

And my less than healthy dinner – instant noodles, mixed with instant soup…

Who says denatured alcohol doesn’t work at altitude? Ok, so it’s a little slow, but it gets the job done.

Quick message to mum and dad. I’m alive!

As the first beams of sunshine reach me, feeding warmth into my body, I creep out of my Tarptent.

My camping neighbours are three Sheffielders – Ben, Neil and Owen – here to bag some peaks. I join them on the hike up to Laguna Ishinku, lying en route to Ranrapalcu, which Ben and Owen intend to climb.

There she be: Ranrapalca, 6162.

It’s a beautiful trail – easier for me, as I’m only carrying a light pack, rather than trudging round with ropes/ice axes/crampons /heavy boots and all the other mountaineering paraphernalia.

I haven’t seen these fellows, Club Mosses, since the high paramos of Ecuador.

Worth an aerial view.

As does this little mountain flower, also found at 4750m. Typically, high altitude flowers are especially colourful, as pollination isn’t always easy to come by.

A strange flowering cacti – note its fruit in the far left corner.

Onwards and upwards: Ishinca peak, 5530m.

Laguna Ishinca lies at the foot of Ranrapalca. Here, you can see the channel that helps regulate the water level of the lake – built to avoid a catastrophe like that of Yungay. In 1970,  18,000 people died in a mudslide dislodged by an earthquake.

Looking down on Laguna Ishinca, 4950m. Standing at over 5000m,  this is the highest I’ve been on the journey.

A glacier tongue – the lowest point of the glacier.

You can just about make out three black dots in the lower, middle part of the picture – climbers descending from Ishinca, the neighbouring peak to Ranrapalca.

The intrepid climbers prepare to set off for their basecamp, on the other side of the lake. Neil and I bid them farewell – we’ve arranged to meet up for chocolate mousse at fancy Christoff’s restaurant on their return.

The hike back: Tocllaraju views all the way.

Back to our camp spot. To the left rises Tocllaraju (6032m), etched with seracs – overhanging ice and snow. In the foreground, the massive moraine bank has spilled out all its innards. A bit like a gargantuan, chocolate liqueur.

Time to begin the descent. Over 10kms of singletrack…

… and fun boulderyness like this. More photos here.

Another climbing group heads for the pampas.

Finally, I’m on dirt again, plummeting down towards the valley floor. Then, it’s just a short stint on pavement until I’m back in Huaraz.
