Some exercise occurred while in Costa Rica, as promised.
Hiking: My friend, Noelle, and I hiked in Manuel Antonio National Park, at the Pur Vida Gardens near Bijagual, and at Carara National Park. These were definitely more leisurely hikes - up to 3 miles each, but we did see a lot of wild things like leaf cutter ants, giant rats (Agouti), ardvarks (Coati), and a million plants and flowers.
Here is a picture from Carara National Park. I'm standing by a tree with a very large buttress. I'm glad I didn't get a big buttress while in Costa Rica, although I did drink a lot of water. HA! I slay me.
Swimming: As expected, the resort did not have a lap pool, but I tired to go on "underwater adventures" as much as possible. Yes, I brought my goggles and went swimming in the pool which curved around the back of the hotel under bridges, near little waterfalls. The other tourists probably wondered what the hell I was doing, but damnit, I got some laps in! I also swam a little bit at the Manuel Antonio beach, and at the Los Suenos beach, but was kind of afraid to go out too far. When you are the only one swimming, you start to wonder what kind of ocean creatures are out there!
