How many parks to visit: Three to five parks is the right number for a backpacker on a trip of three to four weeks, and two to three if you have under two weeks. Argentina’s distances punish anything more. Each extra park means another long bus day, another entry fee, and less time on the trail, which is the whole point. A big trekking park deserves three days, and a quick viewpoint park one. Collecting ticks is poor value, so spend your days in fewer places.
Choosing between kinds of parks: The southern mountain and glacier parks give the most dramatic hiking but cost the most in money and planning.

Argentina’s distances punish anything more. Each extra park means another long bus day, another entry fee, and less time on the trail, which is the whole point. A big trekking park deserves three days, and a quick viewpoint park one. Collecting ticks is poor value, so spend your days in fewer places.
Choosing between kinds of parks: The southern mountain and glacier parks give the most dramatic hiking but cost the most in money and planning. Wind, crowds, and booking rules cost you time and comfort, though the trail networks are the best in the country, with clear signs and reliable bus access. If you have strong hiking appetite, put these first and accept the price. The northwest and high desert parks cost a third as much, come with sparse services and slower transport, and suit travelers who like improvising and altitude. The northeast subtropical parks suit short, humid visits of one to two days, and are easy on the wallet but poor for long hikes. The pampas and eastern lowland parks are the weakest value for most visitors: flat, buggy, and thin on infrastructure, they only make sense if you love birdwatching. Skip them on a short trip.
What it costs: Entry fees for foreigners at the big southern parks run roughly US$20 to 45 per visit, sometimes valid for several days, while northern and central parks typically charge US$3 to 12. Fees can be paid in pesos, and prices are revised often because of inflation, so check current rates before you go. Budget per day on the Patagonian trekking circuit at US$50 to 90 if you camp and cook, more if you use refugios (beds often US$25 to 60, meals extra, and some require full board). Camping inside parks is typically US$5 to 25 a night. In the north, US$30 to 55 a day covers hostel dorms, buses, and entry. Guides are not required on most popular trails but are mandatory for some glacier walks and restricted areas. Expect US$60 to 200 for guided glacier hikes or boat trips. Buses to park gateways run roughly US$5 to 15 per hour of travel, and shuttle transfers to trailheads add US$5 to 20.
The cheapest way to save money is to carry your own food from a supermarket in the gateway town, because prices inside the parks and at remote refugios are two to three times higher. Paying for a guided day when a self-guided trail exists is rarely good value. The one splurge worth the money is a single well-chosen boat or glacier excursion, which gives access that walking cannot.
Safety: The biggest risks are weather and underestimation. Patagonian wind gusts can exceed 100 km/h and conditions change within an hour, so carry a windproof shell, warm layers, and a map even on marked trails. Rivers swell after rain, and water crossings can turn dangerous. In the northwest, altitude of 3,000 to 4,500 meters causes headaches and nausea, so ascend gradually and drink plenty. Sun at high elevation and in the south, where the ozone layer thins in spring, burns quickly, so bring a hat and SPF 50. Register with rangers where required, and tell your hostel your route. Mountain rescue is limited and can be costly, so travel insurance that covers trekking is worth buying. Tap water is usually safe in the south, but treat stream water in the north.
Cultural and practical considerations: Argentines tend to eat late and move slowly, and rangers and bus staff may be informal about schedules, so confirm departures in person. Fire bans are strict, especially in Patagonia where wildfires have devastated forests, and open fires are often illegal outside designated spots. Pack out all trash, because many parks have no bins on the trail. Where indigenous communities such as the Mapuche or Kolla live near or within park areas, ask before photographing people or entering community land. Cash in small pesos is useful for fees, campsites, and rural shops, since card terminals fail often.
