This is half a suggestion for a good ride in South America, but I don't know where it is exactly.
That's why I'm posting it up, hoping someone might recognise it and can tell me exactly.
About 10 years ago I saw an advert in a small hotel in Quito, for two Swiss ex-pats who gave guided off-road tours up into the mountains above Quito. So I had a go.
Just me and one of the Swiss.
A brilliant day, that I could not have done without his local knowledge.
We followed a disused railway for a while, which went over this bridge.
I took the photo and the Swiss guide is crossing the bridge. I then rode over after him. I'm quite pleased with the photo because it looks (to me) a whole lot more scary than it actually was. It was a good wooden surface between the rails, the whole bridge being quite wide, so you couldn't look down!
The only disappointment was my cheap compact camera wasn't working very well, my guide wasn't sure he'd be successful in taking a photo of me as I went over, so I took the photo of him going over.
The tunnel was shortly after the bridge. The mud is higher up the mountain somewhere.
Parts of the disused railway were well used by pedestrians. In places it had collapsed into mud holes which made it interesting!
I didn't take a detailed map with me, nor kept any notes.
So, does anyone recognise where this is and can pinpoint it? Sufficient for me to find it on a map or on GoogleEarth? From memory I think it's NE of Quito, not very far, maybe about 6 or 8 miles out or so. (Or that might all be completely wrong - memory's not too good these days!)
Thanks. Good riding.
