After the wasted journey to the cinema and to check out the embassies we went back to the hostel but took a wrong turn because we were so distracted by a bridge that we crossed it even though we had no idea where it actually led. It didn't lead anywhere we wanted to be, in fact the opposite, it took us on a long route to the middle of nowhere, into what looked like the slums of La Paz. It didn't feel unsafe in any way but just had really run down shacks, roads and paths and the altogether appearance wasn't that great. At least it was high up in the valley and we had an amazing panoramic view of the city.
We wondered a while and still couldn't get our bearings, just went round in circles, went back to the main road and then realised exactly where we were and how we were going to get back to the hostel. The walk we had done was pretty much end to end of the city, from the widest points, it took most of the afternoon but I managed to see most of the city, even parts I would never feel the need to venture to.
