Caribe Tours goes to Jarabacoa 3-4 times a day. It does stop in La Vega for about 10 minutes. 280 pesos last time we took it.
So it stops or we need to change buses, no biggy, but nice to know. Wouldn't be the first time I've stayed on a bus here while I watched the bus I should have been on drive off!
so the price went up a bit... and yes, it was only 10 minutes in la vega, but i did have to switch buses
