A week ago yesterday we went whale watching.
Negotiated a taxi for the day... US$110
E-mailed Kim do do the tour with her, US$50 (x3)
$260 for three of us. We stopped off for food on the way back and had a great day. This was from Cabarete, you could probably get something similar from Sosua for not a huge amount more. Admittedly, we 'asked around' before we got that price for the taxi but even standard from Sosua I'd think you could get it for about $150. Kim's tour is very informative on a really good boat. I've posted some photos on...
