For the longest time I’ve wanted to visit Yalepa, a small village south of PV, and the easiest way is catching a water taxi from Los Muetos pier. The taxi takes about 45 minutes and costs about 125 pesos one way. There is a sign right at the pier and a guy who will sell you a ticket.
I believe the water taxi goes to Yalepa every hour or two but if you just missed one then have a seat at C&C’s, order a margarita and enjoy the scenery while you wait. When the taxi comes they will yell out for everyone to get into the boat. Now one thing to think about is you will probably get your feet wet because you’ll be wading up to the boat. Getting in and out of the boat is a bit cumbersome so if you aren’t that nimble then you may want to book a day cruise trip there instead.
