I have a connection with a guy on the beach there that offers : snorkeling trips, fishing trips, banana boat rides, para sailing. Let me know if you have interest. Going to get quotes on here soon! Also they have beach volleyball, some daily activities, Kayaks, paddle boards, kids play areas:)
Feel free to leave the resort if you want for excursions. I dont have any direct companies but have done them before and they are great
Downtown Puerto Vallarta is approximately a 10 minute cab ride. Have been told it is safe and they will pick you up right out front of the hotel . Approx 10 $ I believe US dollars.
