Catch a taxi from where you are staying to the bus stop located near the Pali supermarket. Should be around 15 cords per person. Buses run at 9:30am, 1:30pm
Catch the Chicken bus marked for Rivas. 30 cords per person, 1.5 hours in a converted school bus. About 90km
From the bus stop in Rivas take a taxi to the ferry station should be about $1 per person if its shared. Confirm the price before you leave, we agreed on $1 per person then it changed halfway through our ride. This wasn’t the first time in Nicaragua when our price changed mod ride, if this happens just be firm and say no and repeat the prices stated earlier, good Spanish helps here.
We got on a 12pm ferry, but check the ferry schedule for up to date timing.
