Standing before the southern slope of Pic du Midi d’Ossau in the Crete Frontiere area of the Aragonese Pyrenees, Spain, we immediately feel the wild beauty that characterizes this part of the mountain range.

Unlike the northern face, which is known for its iconic twin peaks on the French side, the southern slope offers a rugged, less‑visited setting. Dramatic limestone cliffs and green valleys stretch below us, inviting us to explore deeper into this natural frontier.

Best Time to Visit

The ideal season for visiting the southern slope is late spring through early autumn (May–October), when trails are clear and weather is stable. Outside of this season, snow and ice make hiking routes difficult without technical gear. Thunderstorms are more common in late summer afternoons, so it’s best to start early in the morning.

Getting There (Transportation & Fees)

Reaching the southern slopes requires crossing from Spain or France:

From Spain (Huesca or Zaragoza):

- By car: Drive to Jaca (~1.5 hours from Huesca), then follow local mountain roads toward Villanúa and onward to mountain trailheads. Renting a car typically costs $45–$80/day depending on the season and vehicle size.

- By bus: Regional buses run between Huesca and Jaca for about $12–$22 each way. From Jaca, local taxi or rideshare may be needed to reach trailheads (cost varies by distance).

From France:

- Crossing the Col du Pourtalet (a border pass road connecting France and Spain, ~1,794 m) is a scenic route and is generally open year‑round depending on snow conditions.

- There are no national park entry fees for viewing the slopes, but some trailhead parking areas near refuges may charge $6–$11 per day during high season.

Hiking and Climbing Routes

The southern slope provides options for both casual hiking and more challenging routes:

- Moderate Trail: From mountain refuges such as Refuge de Larribet, a marked trail climbs toward Crete Frontiere. A full day (5–7 hours) is typical for this hike.

- Advanced Routes: Serious climbers can follow harder ridges; professional guided climbs (dual summit routes) usually cost $195–$400 per person, including gear and insurance.

Always carry plenty of water, a detailed map or GPS, and sturdy footwear; the terrain can be rocky and steep.

Accommodation (With Approximate Prices)

We recommend basing ourselves in Villanúa or Jaca, towns with good food, lodging, and access to trails:

- Budget Inns & Guesthouses: $65–$110 per night.

- Mid‑Range Hotels: $110–$155 per night with breakfast.

- Mountain Refuges: Basic lodges like Refuge de Larribet typically offer dorm-style rooms from about $28–$38 per night, often including breakfast but no dinner. Advance booking is highly recommended in summer.

Dining Options & Prices

Dining around the Aragonese Pyrenees is hearty and satisfying:

- Local Restaurants in Jaca/Villanúa: Most serve regional mountain cuisine with typical meal prices of $17–$33 per person (main dish with drink).

- Picnic Supplies: A local grocery store in Jaca or Villanúa lets us stock snacks, sandwiches, and drinks for trail days, often more cost-effective than restaurant dining.

Breakfast is sometimes included in guesthouse stays, but for lunch on trails, plan to carry sandwiches, fruit, and water.

Practical Tips for Hikers

- Start Early: Summer storms can develop in the afternoon; hitting trails before 8:30 am gives cooler temperatures and better light for photos.

- Pack Smart: Essentials include sunscreen, hat, layered clothing, and a first-aid kit. Even in summer, high altitudes can be chilly.

- Trail Safety: Southern slopes get full sun exposure; hydration is key, as shaded areas are limited at higher elevations.
