It's worth it, but if you're not Argentine, be prepared to spend triple the amount! - Arriving at the place is strange, as it is a restaurant that offers the tour. There is no tariff, and at the time of purchase you discover what we consider to be abuse. For foreigners the price is different. 3x more than for Argentines. Children pay half, foreigners pay US$22.50. The cost for visiting was US$45 for foreign adults, while US$15 for Argentines. As in some large metropolises, there are incentives for local residents to visit (e.g. Christ and Pão de Açúcar in RJ, there is the Rio passport, a discount for city residents), however, charging foreigners 3x more was a certain amount of abuse . You drove 70 km on dirt roads, so since you're there, you won't miss the experience, unless it's going to be too tight on your budget, especially if you're with family, children, etc. The tour is cool, there are many penguins, and it is possible to get closer as many are on the edge of the trail, however, 1:30 in total is not enough, as you could enjoy the place more, appreciate the landscape. The price is abusive, considering that you yourself drove your car from the restaurant, a few more km, to the safari bus pick-up point. The cost of this tour is the equivalent of going out to see whales, something that actually involves a high investment, vessel, crew, fuel, logistics to place/remove the vessel from the sea.
