If you use one of the taxis at the resort it will be around 80-100 dollars, you would be better off getting up to the main road and taking the publico into Puerto plata then catch another publico to Sosua, then one to Rio Sanjuan and get off as you pass Las Canas in Gaspar Hernandez. The taxis at the resorts and the airports are all ripoffs. If you dont want to use publicos get into Puerto plata and take a taxi from Puerto plata it will save you lots of $$$$
