My husband has a business trip planned in PR coming up in two weeks. I'm trying to see if I can take some time off and join him. I would fly in on Wednesday afternoon, be in Ponce while he works until Friday, then we'd spend Friday afternoon/evening and all day Saturday together in San Juan. So what I worry about is being "on my own" in Ponce exploring and being a tourist by myself for a day and a half in Ponce. I'm not a stay at the beach all day with a book type of person. I want to explore, hike, have an adventure. I was looking into the Caja de Muertos day trip (seems safe enough if I'd be with a bunch of other tourists) but they don't run on Thursdays when I would want to go. Any suggestions for "safe adventures" or warnings for a single gal at it by herself in Ponce?
