A Member-First System You Have to Use as a Non-Member
Club Andino Bariloche (CAB) owns and operates most of the refugios in Nahuel Huapi National Park. It is a non-profit mountain club, founded in 1931, structurally modeled on the German and Austrian alpine clubs. Its members pay dues, vote on leadership, and get substantial discounts on hut stays.
The booking system, registration workflows, and payment methods are all optimized for those members. Foreigners are not excluded — they're just second-class users of infrastructure that assumes you're local, speak Spanish, own an 8-digit Argentine DNI, and know the social rules.
This is not malice. It's parochialism. And it's the single most important thing to understand before you try to book a refugio stay.
Mental model: When you evaluate any trekking system, ask "who built this, and for whom?" If the answer is a local non-profit (CAB, the German Alpine Club, Nepal's TAAN), expect the workflow to assume knowledge and credentials the foreigner lacks.
The huts you need to know
| Refugio | Elevation | Beds | Operator | Location |
|---|---|---|---|---|
| Frey (Emilio Frey) | ~1,700m | 40 | CAB | Below Cerro Catedral's granite amphitheater |
| San Martín (Jakob) | ~1,600m | 80 | CAB | Laguna Jakob |
| Italia / Manfredo Segre (Laguna Negra) | ~1,650m | 60 | CAB | Laguna Negra basin |
| López | ~1,620m | ~40 | CAB | Below Cerro López |
| Otto Meiling | ~2,000m | 80 | CAB | Tronador / Pampa Linda |
| Agostino Rocca | ~2,000m | 60 | CAB | Tronador |

The 7-day rolling reservation window
This is the most important rule and almost no travel guide mentions it:
Refugio Frey accepts reservations no more than 7 days in advance for groups of 1-7. Groups of 8+ can book up to 20 days out.
Source: Refugio Frey — Reservations (official).
What this means practically
- You cannot lock in a Frey bed for a trip you're planning 3 months ahead. The system won't let you.
- You start refreshing the reservation page exactly 7 days before your target date. Peak season beds can disappear within hours.
- If you're coming on a fixed international itinerary and Frey is full when you try, you have three options: (1) walk up and hope, (2) sleep at the nearby Piedritas camping, (3) skip that leg of the traverse.
- Groups of 8+ have a massive advantage because they can book 20 days out. Solo travelers and couples are at the back of the line.
This inverts every "book refugios months in advance" piece of advice you'll see online. Those guides were either written for TMB huts in Europe or by people who didn't actually book Frey.
Why this rule exists
CAB's system is designed so that members (locals who can be flexible) get priority and tourists (who want to lock in months ahead) have to compete on short notice. It's not a conspiracy — it's a member-first policy applied uniformly.
The DNI requirement
Several CAB and Nahuel Huapi workflows request an Argentine DNI (Documento Nacional de Identidad) — an 8-digit national ID number that foreigners don't have.
Examples where this surfaces:
- Some CAB online payment forms
- The park's Registro de Trekking form (though this one accepts passport numbers with care — see the bureaucracy checklist)
- Member discount eligibility flows (which you can ignore, since you're not a member)
Workarounds
- For payment forms: most refugios accept payment at the hut itself, in cash, on arrival. If an online form demands a DNI you don't have, skip the online payment and pay on arrival.
- For the Registro form: enter your passport number in the ID field. Some foreigners report the form rejects it; others report success. This is an open question tracked in the research.
- When in doubt, email the refugiero directly — most have WhatsApp and will confirm your booking in broken English if you write in clear short sentences.

Cash only at the huts
There is no internet at the refugios. Which means:
- Food and drink at refugio kiosks: Argentine pesos only, cash only
- Extra nights if you decide to stay longer: cash only
- Any on-the-spot purchase: cash only
You can pay your pre-booked stay via transfer/online methods. But everything else at the hut — dinner, breakfast, a beer, a bar of chocolate, an extra blanket rental — is cash.
How much cash to bring
For a 3-day traverse eating at the refugio kiosks (not just relying on pre-booked dinners), budget:
| Item | Per day | 3 days |
|---|---|---|
| Dinner at refugio (if not included in "full board") | ~ARS 17,500 (~$12) | $36 |
| Breakfast at refugio | ~ARS 5,000 (~$3) | $9 |
| Snacks / coffee / drinks | ~ARS 5,000-10,000 (~$3-7) | $15-21 |
| Per-person minimum for food only | ~$18-22/day | ~$60/person |
Add ~$30-50 for emergency cash reserve. Total: ~$100-150 USD per person in cash for a 3-day traverse — most of it in Argentine pesos, exchanged in town before you start walking.

Who runs each hut
CAB owns the buildings. The day-to-day operation is contracted to refugieros — private hut keepers who pay CAB for operating rights and retain the meal/drink revenue.
This explains a lot:
- Cash-only food economy: it's the refugiero's own money, not CAB's. They want cash.
- Variable service quality: different refugieros run their huts differently. Frey and Jakob are known for stricter operators; smaller huts can be more flexible.
- Personal relationships matter: a WhatsApp message to the right refugiero can hold you a bed. Nothing about this is in an English-language booking interface.

The member discount (why there's a two-tier price)
CAB members with more than 6 months of tenure receive:
- 80% discount on bed (pernocte) costs
- 30% discount on food at refugios
- Access to a limited number of free refugio nights per month
Source: Club Andino Bariloche — Beneficios socios CAB.
This creates a large effective price wedge between locals and tourists. It's not a formal "tourist price" like some national parks impose — it's a member benefit that happens to make foreigners pay the full rate.
Can foreigners join CAB? Technically yes. Whether it's economically worthwhile depends on how many refugio nights you plan over the next several years. For a single 7-day trip, it's not worth it. For someone planning multiple Argentine trekking trips over 5+ years, it might be. CAB membership dues for non-Argentine residents are poorly documented in English — an open question in the research.
How to actually book a Frey-Jakob-Laguna Negra traverse
Here's the concrete sequence, stripped of guidebook assumptions:
- ~30 days before your trip: Decide your exact traverse dates. You cannot lock refugios yet.
- ~20 days before: If you have a group of 8+, now is when Refugio Frey opens its extended reservation window for you. Solo/small groups: still waiting.
- ~7 days before your first night at Frey: Refresh refugiofreybariloche.com/reservations obsessively. Book Night 1 as soon as it opens.
- Simultaneously: Book Jakob (Refugio San Martín) and Laguna Negra (Refugio Italia) via the Club Andino Bariloche booking portal. These huts are larger and have more availability.
- ~48 hours before departure: Complete the mandatory Registro de Trekking. This is free but enforceable — see the bureaucracy article.
- Day of departure: Pick up any pre-trek gear rentals from a Bariloche outfitter, withdraw cash from an ATM (limits apply — do this across multiple withdrawals if needed), and take a taxi to the Villa Catedral base.
- Before stepping on the trail: Verify the weather forecast, especially wind and visibility for the Paso Schmoll / Brecha Negra sections. If the forecast is bad, delay — the traverse is not safe in high wind.
Bottom line
The CAB system works beautifully if you understand the rules. It's free or near-free as a cooperative mountain club, the huts are well-run, the refugieros are often welcoming, and the mountains are spectacular. The problem is that none of the rules are published in English, the booking UI doesn't explain itself, and every travel blog tells you to "book months ahead" — which is the one thing you cannot do.
Plan like a local, pay like a foreigner, and the system works. Plan like an Inca Trail tourist and you'll be sleeping at the trailhead.
