Anyone traveling by air within the US is familiar with the low-cost budget airlines such as Southwest and AirTran or the very high quality, yet cheap, JetBlue. The Seattle Times informs its readers via a recent article about low-cost airlines in Latin America.
An interesting site is TrekNature, Learning about Nature through Photography. The site is less than a year old and is “dedicated to fostering a global community interested in nature photography from around the world. ” Photos are from all over the world but a large number are from South America. Included are wonderful close-up photos of plants and wildlife. For each photo are photographer notes, specifics about the camera and settings that was used, as well as critiques from other TrekNature members. The critiques share information about the best techniques for photographing nature, such as this photo of a transparent winged butterfly from Brazil. Incredible! I’m very excited about this site and will be spending a lot of time here. TrekNature is a great resource for photographers, nature lovers, and travelers to South America.
Long distance buses in Argentina are usually very comfortable. Just be sure to avoid the semi-cama buses if you want to get the most comfortable seats. Different bus lines will call the better class of bus service by different names, usually coche cama or ejecutivo. Strange as it sounds, I actually enjoy traveling 20 hours by bus in Argentina.
Here are some links to the Web sites for the most common bus companies. But, perhaps the best way to get tickets is just to go to the bus station in Retiro (just north of downtown Buenos Aires) two or three days before your trip. The station is arranged by destination. So, look for the color-coded signs to the region of Argentina where you want to travel and then browse among the desks of the bus companies going to that region.
