Yes, the alternative route. To get to La Paz, we had to take a minvan back the way we'd come (yes back across into Peru), cross the border, jump in another mini van to another border crossing back into Bolivia, queue for about an hour to get another exit stamp from Peru, and once in Bolivia, jump in a bus to La Paz, stopping once at an army check point to have our passports inspected. The total journey time: 6.5 hours.
But we got to La Paz safely, and checked into a hostel. I'd been carrying around a cold for a few days, but arriving in La Paz seemed to make it worse. I also started to get a few stomach problems to go with it. In fact, by the second day, I needed to be within 10 metres of a toilet at all times. Kim & Eric weren't too happy with the hostel we were in, so they moved to another while I stayed put. After a couple of days of doing very little, I decided it was time for some antibiotics, which – fortunately in Bolivia – are over the counter, and very cheap. That sorted me out pretty quickly, and since I'd lingered in La Paz for 5 nights, I decided it was time to move on. Kim & Eric were heading north to the jungle, but I wanted to go south, so I said my goodbyes (via email) and jumped on a bus.
I passed through Cochabamba and Surce, two very nice cities (the towns in Bolivia seem to be much nicer than those in Peru for some reason), but where I did very little of interest. My main aim was to get to Potosi, the worlds highest town (at 4060m), famous for it's mining industry. Arriving in Potosi, I jumped off the bus and into the usual taxi to get to the hostel. The driver was pulling away when another guy stopped him and jumped in the back with me. It was a little odd, but sometimes they pool taxis to make it cheaper.
Then the driver told me it was going to be 10 Bolivianos (more than I expected) and demanded I pay now. Hmm, also odd, I thought, but handed over the cash. Just as we were pulling away again, yet another guy sporting a very fake looking “Tourist Police” badge jumped in the front seat and started talking to the driver. As we took off, I thought this was far too suspicious (have heard far too many dodgy taxi stories). “Por favor, pare!” (please stop) I announced, and – maybe as we were in a fairly busy area – the driver complied. The “police man” tried to convince me to stay, but I was having none of it, and jumped out. It cost me 10 Bolivianos (less than £1), but it earned me a good story.
The main attraction in Potosi for travellers is to do a tour of the mines, unique in the world because it's a live mine – i.e. there are people working there while you're inside. Also, it's a Health & Safety officer's wet dream. Before entering the mines, we visited the miner's market where we bought gifts for the miners – cigarettes, coca leaves, dynamite, and – most popular of all – large bottles of Coke. The dynamite, by the way, can be bought freely, including by kids. That's probably because of lot of the miners are actually kids – they start as young as 13.
We left the mines, and the guide wanted to light some dynamite for us. I guess we were running a bit late, so he prepared and lit the dynamite in a huge rush, threw it to a “safe” location (again, where was Health & Safety?), and had us run far enough away to see (and feel) it go off. We jumped into the bus, headed back to the hostel (most of the tour group was from the same hostel), and made a bee line to the showers. By that stage, it was definitely necessary for all of us.
