I climbed Manquehue two years ago, when my back was still fragile after surgery. That time, we'd climbed from La Piramide via a route that goes most of the way to the top of Cerro Carbón. Today, with a friend who often visits Chile and loves getting out into the hills, I tried the route via Via Roja.
The route via Carbón had taken us about 4 hours in total to get to the top at a very relaxed pace. Starting from Via Roja was supposed to take less than 2 hours. I arranged to meet my friend at 11am, and I thought I would cycle to the start of the climb. I set off at about 10.30, and by 11am I was on Via Roja, a mile and a half from where we were meeting. But what I hadn't checked was how high the end of Via Roja actually was. It's just over 1000m above sea level, so I had a 400m ascent to do. It was a great climb, but tough going with an average gradient of 7.5%. By the time I reached the end of the road, my friend and her friends had got bored of waiting and set off.
So I set off on my own. It was an amazingly steep climb, much tougher than the route via Carbón, but also much quicker, and after an hour and a half I got to the top, not too far behind my friends.
Going down was much tougher on the loose and slippery ground. We somehow ended up a little way from the route we'd taken on the way up, on a much steeper and more precarious path. So it took pretty much exactly the same time to get down as it had to go up. The cycling was a different story. It took me about a quarter of the time to go back down Via Roja as it had to go up it, and I carried the momentum all the way home. In total it took me 5.5 hours to get from my house to the top of the mountain and back.
