There is something magical about waking up under the clear skies of the Sierras de los Comechingones, putting on your boots, and heading out to find that trace of pure nature that only San Luis offers. If you are one of those who prefer the sound of the wind through the molle trees and breathtaking panoramic views over the urban hustle and bustle, Villa de Merlo has a treasure waiting for you.

At Solar de los Pájaros, we host guests looking for a real disconnect, and we always suggest they explore the trails of the Mogote Bayo Reserve. We know, from our own experience and from what our visitors tell us when they return feeling renewed, that walking through this protected area is the most authentic way to connect with the third microclimate in the world, surrounded by native flora and the majestic flight of condors.

In this guide, we detail everything you need to know to explore this natural paradise, from its most secret corners to the difficulty levels of each section. Keep reading and discover, at the end of this article, the perfect plan to get the rest you deserve and recover your energy after a day in the mountains.

Step 1: How to get there and prepare for the adventure

To begin your journey through the trails of the Mogote Bayo Reserve, the first thing you need to know is its strategic location. The reserve is located in the eastern foothills, about 5.8 km from the historic center of the Villa. It is accessed by going up Avenida de los Césares toward the Rincón del Este area.

Due to the distance and the slope, a vehicle (private car or taxi) is required to reach the entrance. Upon arrival, you will find the portal where visitor registration takes place. It is important to note that entry is free, as it is a Provincial Reserve that protects the mountain ecosystem.

Hours and logistics:

  • Opening days: Thursday to Sunday and holidays.
  • Entry hours: 09:30 AM to 03:00 PM (the entire premises close at 05:00 PM).
  • Local Tip: Come early. Being a protected area with hiking quotas, arriving during the first shift ensures a quieter experience and allows you enough time to complete the more difficult circuits before the trails close.

Step 2: The Low Difficulty Trail (Ideal for families and contemplation)

Once registered, the first section invites you to immerse yourself in the native forest. The low difficulty trail is perfect for family hiking, as the terrain is relatively easy to navigate and very well marked. This journey is a live botany class. You will walk among talas, molles, and espinillos, smelling the unmistakable scent of the flora growing along the path.

This interpretive trail is designed for you to stop and read the signage explaining the importance of the Merlo microclimate and how the local flora adapts to the altitude. It is an ideal route to take at a very relaxed pace that ends at natural viewpoints with spectacular views of the Conlara Valley.

  • Local Tip: If you are going with children, stay quiet. Sometimes you can see colorful lizards or even a small gray fox peeking out curiously from between the bushes.
  • Fun Fact: This sector is a favorite for nature photographers because of the light that filters through the treetops during the morning.

Step 3: The ascent through the Medium and High Difficulty Trails

If you have experience or simply want to push your lungs to the limit of mountain purity, you can opt for the medium and medium-high difficulty trails. Here the terrain changes: the slope becomes steeper and the ground is rockier, typical of mountain granite.

This ascent takes you toward the "Mogotes" area. As you climb, the vegetation becomes shorter and the famous Tabaquillos appear—trees with reddish bark that peels off like paper, unique to high-altitude areas. The goal of this section is to reach the highest observation points, from where Villa de Merlo looks tiny and the horizon disappears into the vastness of the valley.

  • Physical effort: The ascent can take between 1 and 2 hours depending on your pace and the chosen trail. Shoes with good grip are required (forget about sandals).
  • Safety: It is vital to always stay within the marked tracks. Going off-trail not only damages the soil and flora, but in the mountains, it is very easy to become disoriented if clouds move in.
  • Natural variation: If you are looking for greater challenges like the Salto del Tabaquillo (Tabaquillo Waterfall), remember that these strictly require a certified guide for safety. At Mogote Bayo, the trails are prepared for self-guided hiking as long as you respect the signs.

Step 4: Observation of Flora, Fauna, and the Flight of the Condor

The Mogote Bayo Reserve is a sanctuary. During your tour, especially in the higher sections, you must keep your eyes on the sky. It is very common to spot Andean Condors using thermal currents to glide. Seeing their shadow projected on the rocks while you walk is an unforgetable experience.

As for the flora, remember that Merlo protects its native species. Extracting plants or herbs is strictly prohibited. Caring for the environment is the number one rule: all waste you generate must return with you in your backpack.

  • Expert tip: Bring binoculars. Not only for the birds but to observe the geological formations of the mountain walls, where black-chested buzzard-eagles and falcons nest.
  • Preservation: The reserve functions as a water recharge zone. By walking on the marked trails, you are helping to ensure that this water cycle that supplies the city is not interrupted.

Step 5: The well-deserved rest after the mountain

After coming down from the trails, the body usually asks for a break. Many tourists choose to stay in nearby areas such as Rincón del Este or the Foothills to be just minutes away from this contact with nature.

It is the ideal time to look for a shaded space, hydrate well, and process the experience. The air with the "third microclimate in the world" feels purer after having conquered the height of the mountain.

  • Services: Remember that the reserve is a protected natural area; there are no commercial shops or fast food outlets inside. Always bring your supplies from the center.
  • Recommendation: Upon finishing, you can visit downtown Merlo to enjoy a handmade snack at the local tea houses, an excellent way to recover your energy.

Step 6: Seasons and technical recommendations

To get the most out of the trails of the Mogote Bayo Reserve, choosing the right date is key.
