A guided trip costs different prices depending on where u go a 1 night trip costs $400 without the travel costs
If you go by yourself you will have to rent a car and your travel prices so it depends on where you fly out of and if you take different flights or a direct one
Most of all of the streams in argentina will have some sort of fish ,but their is a lot of the the major streams to choose from
The flys and or are bait all depend on the type of year and the type of flies that are hatching
In my opinion it is a good place to go and fish because they have some world class fishing waters
Depending on where you decide to go depends on how easy or hard to get to most of the streams and rivers i found are easy to get to in sections ,but some of them or parts are hard to get too
Certain streams hold different types of fish their are some parts of the streams that have certain fish that 30 miles down don’t have
