Hidden Gems: Ruta 40 (Patagonia Section)

Why it's hidden: Its remote location and the largely unpaved road conditions deter most travelers who stick to easier access points on Ruta 40. The border crossing itself is also very quiet, meaning fewer international visitors.

How to find it: From Gobernador Gregores on Ruta 40, head west on RP 25 to Perito Moreno, then south on RP 41 (Corredor del Lago) which is unpaved but generally well-maintained gravel. The loop can be done from Los Antiguos (RN 40) via RP 43 to Lago Posadas and then continuing on RP 41 to Paso Roballos, then back north on RP 40, or vice versa. The section of RP 41 from Lago Posadas to Paso Roballos is particularly scenic but rugged in places. Parking is available at various scenic viewpoints along the route. Road conditions vary, expect gravel, washboards, and occasional potholes. A high-clearance 4x4 is recommended, especially after rain or in early/late season.

Best time: Late spring (November) to early autumn (April) for best weather and road conditions. Strong winds are common.

Why it's hidden: These viewpoints are not officially marked or publicized by the main site. They require local knowledge or diligent exploration off the main access road, which can be rough.

How to find it: From Ruta 40, take RP 97 towards the official Cueva de las Manos site (well-signed). Before reaching the main site's parking area, pay close attention to unmarked dirt tracks branching off RP 97 to your left (if coming from Ruta 40). Some lead to precarious but rewarding spots overlooking the canyon. Consult a good offline map (like Maps.me or Gaia GPS) for potential tracks. Parking is informal pull-offs. The main road (RP 97) is gravel, usually passable for 2WD, but these side tracks can be very rough and require a 4x4.

Best time: Morning or late afternoon for best light on the canyon. Avoid midday crowds at the main site if visiting both. Spring and autumn offer pleasant temperatures.

Why it's hidden: While Estancia La Leona is somewhat known, the specific route via RP 29/33 and the associated petrified forest are not part of standard itineraries, overshadowed by the larger Sarmiento Petrified Forest.

How to find it: Estancia La Leona is directly on Ruta 40, about halfway between El Calafate and El Chaltén. To reach the petrified forest, from the estancia, head north on Ruta 40 for a short distance, then take RP 29 east. Follow RP 29 for about 30km, then turn north onto RP 33. This gravel road leads to a less-visited section of petrified wood. Enquire at Estancia La Leona for the most precise directions and current road conditions, as access points can be informal. Parking is informal at the estancia and along the RP 33. Both RP 29 and RP 33 are unpaved, challenging gravel roads, best tackled with a 4x4.

Best time: Any time of year the roads are clear of snow (typically October to May). Wind can be very strong, so clear, calm days are best for exploration.

Why it's hidden: Its extreme remoteness and difficult access via long stretches of unpaved road mean only the most intrepid travelers reach its borders. It requires significant commitment and preparation.

How to find it: From Gobernador Gregores on Ruta 40, head west on RP 25 for about 90km, then turn south onto RP 37. This road is entirely gravel, can be very rough, and requires careful driving. It's approximately 100km from RP 25 to the park entrance. There are basic campsites and a refugio inside the park. Parking is available at the ranger station and designated trailheads. A high-clearance 4x4 is essential, and check road conditions with park rangers beforehand as some sections can become impassable.

Best time: Summer (December-March) offers the best chance of clear roads and hiking weather, but be prepared for Patagonian winds and sudden weather changes.

Why it's hidden: This area is far from the typical Patagonian circuit of mountains and glaciers, often skipped by those focused purely on natural wonders. It requires a significant detour from the main Ruta 40 in Chubut.

How to find it: From Ruta 40 near Esquel, head east on RN 25 towards Trelew and Rawson. Gaiman and Dolavon are located along this route, easily accessible from Trelew. Gaiman is about 38km west of Trelew, and Dolavon is further west. The roads are paved and well-maintained. Parking is readily available in both towns. This is an easy and pleasant drive on paved roads.

Best time: Year-round, though spring and autumn offer milder weather. Summer is pleasant but can be busy with Argentinian tourists. Check for local festivals or eisteddfods (Welsh cultural festivals).

Why it's hidden: Located just off a section of Ruta 40 that many travelers rush through between El Calafate and El Chaltén, its unassuming turn-off means it's frequently overlooked.

How to find it: Lagunas Azules are located roughly 50km north of Tres Lagos on Ruta 40. Look for a well-marked but unpaved turn-off to the east. The gravel track leads for about 5km to the lakes. Parking is informal at the edge of the lakes. The gravel road to the lakes is generally passable for 2WD vehicles in dry conditions, but can be rough and requires careful driving.

Best time: Late spring to early autumn for clear access and optimal light conditions on the lakes. Avoid strong winds if possible.

Why it's hidden: It's a significant detour from the main Ruta 40, located further north in Mendoza province but accessible when traversing the northern Patagonian sections. Access is restricted and requires a guided tour with specific permits.

How to find it: From Ruta 40, the closest major town is Malargüe (Mendoza province). Access to La Payunia is strictly controlled; you must enter with an authorized guide and a 4x4 vehicle. Tours typically depart from Malargüe. You cannot self-drive into the reserve without a guide. Parking is available at tour operator offices in Malargüe. Roads within the reserve are rugged 4x4 tracks.

Best time: Spring (October-November) and Autumn (March-April) offer the most pleasant temperatures. Summer can be extremely hot.

Why it's hidden: This section of RP 41 is known for its challenging road conditions, extreme remoteness, and lack of services. It's often only traversed by locals or very adventurous travelers seeking solitude.

How to find it: From Lago Posadas, continue north on RP 41. The road skirts Lago Pueyrredón and then heads north towards Lago Ghio and eventually connects with RP 37 (the access road for Perito Moreno National Park). The entire stretch is unpaved, gravel, and can be very rough, with steep sections and river crossings (seasonal). It requires significant driving skill, a high-clearance 4x4, and self-sufficiency. There are no services for hundreds of kilometers. Parking is informal pull-offs along the road. Check local conditions diligently before attempting.

Best time: Summer (January-March) provides the highest chance of passable roads, but always be prepared for rapid weather changes and potential road closures.
