You have to go to the old bus station to get a bus to Chapala lake. We chose to go to Ajijic and the direct bus took just over an hour. On the way back we took the bus via Chapala and it took nearly 2 hours.
the town of Ajijic is very beautiful, colourful houses, many flowers and trees, nice vibe and glorious setting with the huge lake and the mountains behind.
We spent hours by the lake just wandering along the very nicely laid out Malecon (lakeside walk) or sitting by the lake itself and enjoying a magnificent sunset. My wife and 13 year old also loved it.
We ate very well at a place by the 'beach', I don't remember the name, but it's near the pier...if you're behind the pier and facing the lake it's the second(last) one on the left hand side.
It would be a nice place to stay, not just to visit in a day.
