Last summer I was travelling with a friend overland from Medan via Lake Toba and Nias to Bukittinggi and from there via Padang all the way to Bandar Lampung in the south. This took a lot of uncomfortable travelling in all sorts of vehicles trough all sorts of roads in various conditions, although a lot of them were very bad, specially those in the highlands in the south. This all took us three weeks.
Although I was carrying my own mosquito net, I mostly used some Baygon insect spray instead, when the use of klamboos in budged hotels was difficult.
More difficulties we had with the food, as it was hard sometimes to find something else than the old ‘masakan Padang’, wich we don’t like at all. It was too spicy for us and mostly far from fresh as it’s stands long times getting ancient behind glass show - cases. We were rather looking for a Chinese restaurant, but sometimes hard to find.
Although in Dutch, from next week Sunday I will post my travel experiences from that trip here on this forum.
