Golf is available. Many golf courses. Horseback riding is available in the little town and downtown and the little town is close to the hotel. Fishing is a must. You don't have to go far to fish and you can deep sea fishing or fish from the top. The marina is 1/8 mile away from the hotel. Also a mall close to hotel for shopping if you don't want to go downtown.
I'm not a big fan of golf or fishing. But when I was in Puerto Vallarta I really liked the snorkeling. There was also this really neat zipline park (I forget what it's called), but it's really fun and great for families. I also know that you can go whale watching in Puerto Vallarta, though when I was there it wasn't the season unfortunately. Next time!
