The Cochamó Valley trek is a roughly 12 km (7.5 mile) hike from the trailhead to La Junta basecamp, taking 4–6 hours each way through dense Valdivian rainforest with constant mud and several river crossings. You need a mandatory reservation through reservasvallecochamo.cl to enter the La Junta sector, you must check in at the trailhead before it closes at 3:00 p.m., and most trekkers hire local packhorses (*arrieros*) to carry heavy gear. The best season is December through March. Below is exactly how to plan it.
Cochamó is often called the "Yosemite of South America" for its sheer granite domes rising above old-growth forest — but unlike Yosemite, there are no roads, no shops, and no rescue services once you're in the valley. It rewards self-sufficient trekkers and climbers, and it's one of the few world-class destinations in Patagonia that still feels genuinely wild.

Getting to Cochamó is really two separate stages, and most travelers underestimate the second one. Stage one is reaching the town of Cochamó. Stage two — the part that trips people up — is getting another ~10 km up a gravel road into the valley to reach the actual trailhead. Arriving in Cochamó town is only half the job.
Almost everyone starts from Puerto Montt (El Tepual airport, PMC) or Puerto Varas, in Chile's Lake District. There are several daily LATAM flights from Santiago to Puerto Montt (about 1h45–2h). From there it's roughly 111 km (69 miles) south to the town of Cochamó.
The route by road: from Puerto Varas, take Route 225 along Lake Llanquihue to Ensenada, then the turnoff toward Ralún and Cochamó (Route V-69). From Cochamó town, it's then about 10 km of gravel road up the river valley to the trailhead — drivable in a normal car in dry conditions, but a 4x4 is safer after rain, and there's no public transport that runs reliably on this final stretch.
Here are your main options for the final leg:
| Option | Time | Approx. cost (2026) | Notes | | Public bus (Puerto Montt → Cochamó) | 2–2.5 h | ~CLP 5,000–7,000 ($6–8 USD) | Buses Río Puelo from Puerto Montt terminal (booth 42), ~3–4 daily | | Bus straight to trailhead (high season) | 2.5–3.5 h | ~CLP 6,500 ($7.5 USD) pp | Not all buses go all the way up — confirm when buying | | Private transfer (airport/Puerto Varas → trailhead) | ~1.5 h | ~CLP 50,000 ($55–60 USD) | Best split among 4–5 people; door-to-door with gear | | Parking at trailhead | — | ~CLP 2,000 ($2.3 USD)/night | At Camping Los Pozones if you self-drive |
The single most important logistical detail: the trailhead access closes at 3:00 p.m. If you arrive later, you cannot enter until the next morning. Several buses leave Puerto Montt too late to make this cutoff, so plan to be at the trailhead by early afternoon at the latest.
This two-stage transport — city to town, then town to trailhead before the 3 p.m. cutoff — is exactly the part that goes wrong for independent travelers. It's also the piece we've built out: door-to-door logistics from your Puerto Varas or Puerto Montt accommodation all the way to the trailhead, timed around the access window and coordinated with your reservation and packhorses, so you don't lose a day standing at a closed gate.
The main trail runs about 12 km (7.5 miles) one way from the trailhead to the La Junta basecamp, following the historic Paso El León cattle route. Most hikers take 4–6 hours, depending on conditions and pack weight. It's rated medium difficulty in distance but harder in conditions.
What to expect on the ground:
A blunt warning the local organization itself gives: if this is your first-ever multi-day trek, Cochamó is probably not the place to start. There are no rangers stationed to rescue you and no medical services in the valley.
La Junta is the basecamp — a wide meadow where the Cochamó and La Junta rivers meet, ringed by granite walls. From here, more than 40 km of trails and 100+ climbing routes fan out. Plan to spend at least 2 nights so you actually have time to explore.
The three classic day hikes from La Junta are El Anfiteatro, Cerro Trinidad, and Cerro La Paloma:
| Day hike | Round trip | Difficulty | What it's for | | El Anfiteatro | Half–full day | Hard, technical | Amphitheatre of granite; climber approach | | Cerro Trinidad | Full day | Hard, technical | The icon — views of the big granite walls | | Cerro La Paloma | Full day | Hard, technical, long | Panoramic; the longest of the three | | Los Toboganes | Short | Easy walk, high risk | Natural granite water slides |
These high-valley hikes require a guide. The terrain is technical, the trails are long, and there have been serious accidents — these are not casual day walks despite the name. A local guide handles the route-finding, the exposure and the timing so you get back before dark.
One route to cross off your list: Arco Iris is currently closed due to rockfall and is not accessible. Don't plan around it, regardless of what older blogs say.
A serious safety note on Los Toboganes: these natural rock slides are beautiful and tempting, but the local organization is explicit that this is where most of the valley's serious accidents happen. Look, don't slide.
For climbers: Cochamó is a full alpine big-wall environment with 100+ routes. Topos are no longer kept at the Refugio — download everything from the cochamo.com climbing folder to your phone before you arrive, since there's no reliable signal in the valley.
Yes. Entering the La Junta sector in high season requires an advance reservation through reservasvallecochamo.cl. There is no national-park-style ticket gate — instead, access is capped at the capacity of the authorized campsites, and your reservation is what lets you in. With 15,000+ visitors between December and March, spots fill early.
How it works:
1. Book your campsite online before you travel. The authorized camps are La Junta, Trawen, Vista Hermosa, and Los Manzanos (plus the Refugio Cochamó lodge). Your reservation includes a conservation contribution that funds trail maintenance and infrastructure. 2. Reserve months ahead for December–February. One season opened with 60% of capacity already booked early on. November and late March/April are easier. 3. Check in and out at the Visitor Center at the trailhead. You must present your reservation and register on the way in *and* the way out — this is the search-and-rescue record if something goes wrong. 4. Respect the entry window. Check-in runs roughly 7:00 a.m.–3:00 p.m. in Dec–Feb (about 8:00 a.m.–2:00 p.m. in March–April), and the trailhead closes at 3:00 p.m.
If you want packhorses, you arrange those separately and directly with the Asociación de Arrieros de Cochamó. A horse costs roughly $50 USD per leg and carries up to 60 kg (132 lb) of gear — so a single horse easily covers two trekkers' heavy bags for the haul in or out. Book ahead, as the arrieros are in high demand in peak season. (When you book a guided trip with us, the packhorses, reservation and campsite are all arranged for you.)
| Period | Conditions | Crowds | Verdict | | Dec–Mar | Driest, most stable; warmest | High (Jan–Feb peak) | Best overall window | | November | Wetter, variable, cooler | Low | Solitude, but muddier and colder | | April | Wetter, shorter days | Low | Quiet shoulder; weather a gamble | | Winter (May–Sep) | Cold, very wet, technical | Almost none | Not recommended for most |
Two season-specific things to know. First, **January brings clouds of *tábanos*** (large horseflies) — avoid dark clothing, which attracts them. Second, "best season" still means rain: this is one of the wettest corners of Chile, so pack as if it will rain regardless of the month.
Our local tip: late February and March tend to be the sweet spot — the worst of the horseflies has passed, the weather is still reasonably stable, and the valley is quieter than the January peak.
The non-negotiables, learned the hard way:
If you're camping and self-catering, buy all food and white gas (*bencina blanca*) in Puerto Varas or Puerto Montt — there are no real stores past Cochamó town. (For a full breakdown, see our Patagonia packing list.)
The main trail to La Junta is doable without a guide if you're an experienced trekker comfortable with mud, navigation and self-rescue. But a guide becomes essential — not just nice to have — when:
A typical guided trip handles the whole chain for you: door-to-door transport to the trailhead before the access cutoff, your campsite reservation, packhorses for the heavy gear, camp setup and meals, and a certified guide for the technical high-valley hikes. You arrive and just walk. Our guided Cochamó trips start from $____ per person — request a quote for your dates and group size.
| Length | Best for | Outline | | 2 days / 1 night | Tight schedules | Hike in, one night at La Junta, hike out next day. Rushed but possible. | | 4 days / 3 nights | The classic | Day 1 hike in. Days 2–3 day hikes (Trinidad, Anfiteatro). Day 4 hike out. | | 7 days / 6 nights | Full exploration / climbers | Add La Paloma, rest/weather days, and climbing or fishing. |
For most first-time visitors, the 4-day version is the sweet spot: enough time to actually see the valley without burning your whole trip on the in-and-out hike.
The most comfortable way to do it: base yourself in Puerto Varas for a few days and go up into Cochamó for just 2–3 nights. You still discover the valley properly, but you bookend the rough camping with a real bed, hot showers, restaurants and lakeside comfort in town — and Puerto Varas is the natural launchpad for the rest of the Lake District anyway (Volcán Osorno, Petrohué, Chiloé). See our Puerto Varas guide for how to build the trip around it.

Yes. A reservation through reservasvallecochamo.cl is mandatory to enter the La Junta sector in high season, and capacity is limited to the authorized campsites. With over 15,000 visitors between December and March, you should book months ahead for the December–February peak.
The main trail to La Junta is about 12 km (7.5 miles) one way and takes 4–6 hours. It's moderate in distance but challenging in conditions — expect deep mud, roots and river crossings in every season. It's not recommended as a first-ever multi-day trek.
You can hike the main trail to La Junta without a guide if you're an experienced trekker. But the high-valley day hikes — Anfiteatro, Trinidad and La Paloma — require a guide: they're technical, long, and have had serious accidents. A guide is also strongly advised for climbers and first-time visitors, since there are no rescue services in the valley.
December to March offers the most stable weather and the driest (though still muddy) trails. November and April are quieter but wetter and colder. January brings large horseflies (tábanos), so avoid dark clothing.
The trailhead access closes at 3:00 p.m. After that you cannot enter until the next morning. Plan transport so you reach the trailhead by early afternoon — some buses from Puerto Montt leave too late to make the cutoff.
Technically yes, but it's rushed and not worth it. The 4–6 hour hike each way leaves almost no time at La Junta. Most visitors stay at least 2 nights to actually explore the granite walls and side valleys.
Packhorses (arrieros) cost roughly $50 USD per horse per leg and carry up to 60 kg (132 lb), arranged directly with the Asociación de Arrieros de Cochamó. One horse comfortably covers the heavy bags for two trekkers on the way in or out, which is why most people use them rather than carrying everything themselves.
No. Arco Iris is currently closed due to rockfall and is not accessible, despite still appearing in older guides. The open high-valley hikes from La Junta are El Anfiteatro, Cerro Trinidad and Cerro La Paloma — all technical and best done with a guide.
