After having a bit of fun going through the traffic of Tuxtla Gutierrez, I took the toll out across the isthmus. It is actually a pretty ride across a lake and with some neat mountains. It is a quick pace at 110km/hr. The only downside is that it is really windy, that gets tiring.
I was originally aiming to our Minatitlan, but there is nothing to that city. Almost no hotels and ugly to boot. So I went another 40 minutes down the road to Acayucan. A little town, but not bad. Better than Minatitlan.
