My family (2 young kids, 2 adults) will be visiting Misiones in March, and want to visit Iguazu (falls and jungle), San Ignacio and maybe Trinidad (ruins), and Esteros del Ibera (wildlife). I was looking at flying from BA to Ciudad del Este, simply because it's the least expensive option.
My question is if I should then rent a car to get around, or take buses? I was thinking we'd go:
* Ciudad del Este to San Ignacio
* San Ignacio to Galarza (in the wetlands)
* Galarza back up to Iguazu
* Iguazu to Ciudad del Este
Having a car would certainly be more convenient, especially since we have pre-school age kids. But is it safe, both in terms of road condition and other risks? Is it economical? Is it easy to take buses (or taxis) between each of these places?
Thanks for any help!
