Senda Costera (Coastal Trail), Tierra del Fuego National Park: Hiking Guide

Is the Senda Costera worth it?

Yes. If you only do one hike in the park, make it this one. It is the only trail that keeps you on the Beagle Channel shoreline for most of the way. You get pocket beaches, lenga and guindo forest, and views of Isla Redonda and Chile’s mountains, without a summit climb. It is not a big-mountain hike like those in El Chaltén or Torres del Paine. One AllTrails reviewer put it well: “The views aren’t as spectacular as some of the other places in Patagonia… but it’s a completely different ecosystem.” Come for the place where forest meets sea; the peaks stay in the background.

Our verdict: it gives you the most coast and forest for the effort of any hike in the park. For normally active people it is a moderate walk, mostly because of the mud and the constant small ups and downs. You can shorten it easily.

Senda Costera distance and difficulty explained

How long is the coastal trail in Ushuaia’s national park? Officially 8 km one way. Most people take 3–4 hours of walking, plus breaks.

Why the numbers differ between sources:

• Distance: APN says 8,000 m. Recorded Wikiloc tracks run from about 8.2 km (5.07 mi) to about 9.3 km (5.78 mi). The longer ones include the walk along Ruta 3 to Alakush or Lapataia. Some tour operators call it “almost 7 km” because their groups finish at a vehicle pickup.
• Elevation: APN’s 70 m is the figure for net change. Cumulative gain from GPS is roughly 120–185 m (397–607 ft on Wikiloc). Andeshandbook gives 273 m. AllTrails shows 1,843 ft (about 560 m), but that is for its 10.2-mile out-and-back version, so ignore it if you are walking one way.
• Difficulty: APN and the Fin del Mundo tourism board (InFuETur) rate it “media”. Andeshandbook and many Wikiloc users rate it easy. AllTrails tags the out-and-back as hard. In practice it is easy to moderate in dry weather and moderate when muddy.

Senda Costera map and GPX

• Official map: the APN and Ushuaia Tourism park map, 2025 edition (a PDF titled “MAPA-PNTDF-ES-2025” on turismoushuaia.com). The older 2022 APN edition is also online. You get a paper map when you pay at the entrance.
• Offline tracks: download a Wikiloc or AllTrails track before you leave Ushuaia, because there is no signal. Maps.me and Organic Maps also show the trail.

Senda Costera route description, section by section

The km and time markers below are approximate. They come from published GPS tracks and walker reports, not official APN waypoints, and assume the Ensenada to Alakush direction at an average pace.

1. Ensenada Zaratiegui trailhead (km 0, 0:00) Start at the information sign by the Ensenada car park and pier. The End of the World post office (Correo del Fin del Mundo) stands here, though it is often closed, so plan to see it from outside. Look south across the bay to Isla Redonda and the smaller Isla Estorbo, with the snowy mountains of Chile’s Isla Hoste and Navarino beyond. The toilets here are basic; APN plans to replace the chemical toilets with new biodigester units.

2. Forest and first coves (km 0–2, 0:00–0:40) The path heads west into lenga, guindo and canelo forest and keeps dropping back to small shingle coves. Look for concheros: grassy mounds and hollows made of mussel and limpet shells left by the Yámana canoe people. They are protected archaeological sites, so don’t dig or remove anything. Expect your first muddy patches and root steps.

3. Headlands and pocket beaches (km 2–4.5, 0:40–1:45) This is the heart of the trail. Short climbs over wooded headlands alternate with descents to quiet beaches facing the Beagle Channel, and this stretch has the best picnic spots. Kelp geese, steamer ducks and cormorants are common on the rocks. Some walkers call a beach roughly halfway along “Playa Verde”, but treat that name as informal.

4. Turning into Bahía Lapataia (km 4.5–7, 1:45–3:00) The trail curves northwest around the base of Cerro Bellavista and starts to follow Lapataia Bay, the only fjord on the Argentine side of the island. Views open up toward the mountains on the Chilean border. You may meet the park’s semi-wild horses here; watch for droppings and give them space. This is usually the muddiest stretch after rain.

5. Final climb and exit to Ruta 3 (km 7–8, 3:00–3:30+) The only noticeable sustained rise comes near the end. You then come out at the second trailhead sign on Ruta 3, at the junction with the road to Lago Roca (Acigami).

6. On to Alakush or Lapataia (optional, +1 km or 15–20 minutes to Alakush) Turn onto Ruta 3 to reach the Alakush Visitor Centre, about 1 km away, for toilets, food and the minibus stop. Or keep going to Lago Acigami or the short Lapataia trails.

How to hike the Senda Costera, step by step

1. Check the season and status. The trail is open November to April only. Confirm with APN or at the park entrance on the day, especially in November and April.
2. Buy your park ticket. Foreigners pay ARS 40,000 (APN Resolución 132/2026, in force since 1 June 2026); our entrance fee guide explains how to pay. Carry your physical passport, because tickets are issued in your name.
3. Download an offline map or GPX track (Wikiloc, AllTrails or Maps.me). There is no phone signal.
4. Get to Ensenada Zaratiegui. Take the park minibus from Av. Maipú and Juana Fadul and ask to get off at “Ensenada”, or arrange a taxi or a tour. Start by 10:00–11:00 if you can.
5. Hike west along the coast for 8 km, following the signs. Allow 3–4 hours plus breaks.
6. Exit at Ruta 3 and walk about 1 km to Alakush, or carry on to Lapataia.
7. Catch your return transport. Be at your minibus stop well before the last return; walkers report the last one at around 19:00 in summer. Or meet your taxi or tour.

Getting to the trailhead and back

Because the trail is one way, getting to the start and home from the end is the main problem. Your options:

Our tip: hike from Ensenada to Alakush, not the other way round. You finish next to food, toilets and the busiest minibus stop, and if you are running late, the Alakush and Lapataia stops are your safety net.

Visiting in October or early November?

In October 2026 the Senda Costera is closed. APN’s season is “November to April”, and it has not announced a fixed 2026 opening date, so early-November walkers should check on the day. Here is what you can do instead:

• Year-round short trails at Lapataia: La Baliza (1.2 km, 30 min), Mirador Lapataia (980 m, 30 min), Paseo de la Isla (1.3 km, 30 min), Senda del Turbal (1.35 km, 40 min) and Castorera (200 m, 20 min). Laguna Negra is officially open, but its boardwalk is listed as under repair. Linked together, they make a pleasant 2–3 hour walking day.
• The End of the World Train plus a park visit: see our national park train tours guide.
• Laguna Esmeralda (outside the park): 9 km return, 4–5 hours, about 220 m of gain (Ushuaia Tourism). It is often snowy or very muddy in spring. On Viator, the Emerald Lagoon Trekking from Ushuaia, Small Group costs from $95 with a guide and lunch, rated 4.7/5 from 92 reviews.
• Guided park tours: some operators run all year. The Tierra del Fuego National Park Tour, Train Optional costs from $52 and is rated 4.8/5 from 509 reviews; ask what route the guides walk while the Costera is closed.

Wildlife and nature on the coastal trail

• Birds: kelp goose (caranca), upland goose (cauquén), Fuegian steamer duck (pato vapor), crested duck, cormorants and Magellanic oystercatcher. Black-browed albatross can be seen offshore. In the forest, listen for the “tac-tac” of the Magellanic woodpecker (carpintero gigante). You may also see austral parakeets and austral thrushes.
• Mammals: the native Fuegian red fox (zorro colorado) is often seen near trails and car parks. Don’t feed it. Beaver damage is everywhere: Argentina’s Ministerio de Marina released 20 Canadian beavers in November 1946, and Minuto Fueguino (21 September 2026), citing official estimates, reports they have colonised around 95% of Tierra del Fuego’s river basins. A CADIC-CONICET survey counted 206,203 dams, with beavers present in every basin of the national park. The semi-wild horses are introduced too.
• Trees and plants: lenga, ñire, guindo, canelo and notro, plus peat bogs (turbales) inland. In autumn (April) the lenga turns red and gold. It is the best month for colour, with fewer people, though the days are shorter and colder than in summer.

Best time to hike the Senda Costera

• Best months: December to March for the warmest weather and longest days. Late March to April for autumn colour. November for spring birds, once you have checked that the trail is open.
• Best time of day: start between 9:00 and 11:00. You avoid racing the last minibus, and coach tours cluster at Lapataia, away from the trail.
• Weather: expect “four seasons in one day”: wind, drizzle, sun and sometimes sleet, even in summer. After rain the trail gets very muddy; an AllTrails reviewer on 15 April 2026 described it as “quite muddy”.

What to pack (checklist)

• Waterproof hiking boots. This is the most important item; trail runners get soaked.
• Waterproof jacket and a warm mid-layer (fleece or down), plus a hat and gloves, even in January
• Trekking poles (useful on muddy descents)
• 1–1.5 litres of water per person. Treat any stream water: a 2020 Universidad de Chile (GEF Castor) study found Giardia and Cryptosporidium in beaver droppings at Karukinka, on the Chilean side of Tierra del Fuego
• A packed lunch and snacks for a picnic on a beach
• An offline map or GPX track, a charged phone and a power bank
• Sunscreen and sunglasses (UV is strong here)
• Your passport (for the named park ticket), the park ticket and cash
• A rubbish bag (carry everything out) and toilet paper
• A small first-aid kit

Food and toilets: the Alakush Visitor Centre reopened in September 2026 after renovation, with a café, a new menu and toilets in excellent condition (El Diario del Fin del Mundo, 15 September 2026). APN lists its hours as 9:00–18:00 daily, while the café’s own past hours were 10:00–17:30, so confirm before you count on it for lunch. Ensenada has only basic toilets.

Safety on the Senda Costera

• No phone signal. Tell someone your plan and when you expect to be back.
• Hypothermia is a real risk even in summer: wet clothes, wind and cold water add up. Carry dry layers.
• Slippery roots, boardwalks and clay cause most injuries. Take descents slowly; poles help.
• Stay on the marked trail. Don’t scramble around headlands at the waterline or climb on the cliffs.
• Don’t drink untreated water.
• Wildlife: keep your distance from horses and foxes, and never feed animals.
• Emergencies: in Tierra del Fuego province, call 107 for medical emergencies and 911 for police and general emergencies; Defensa Civil is 103. The park office (Intendencia, San Martín 1395, Ushuaia) is on +54 2901 577931 / 577993. Rangers are stationed at the entrance and around Lapataia and Alakush.
• Timing: there is no official latest start time for the Costera. In practice, start by about 14:00 at the latest so you make the last minibus. The park is open 8:00–21:00 from December to February and 8:00–20:00 in March, October and November.

Variants and combinations

• Reverse direction (Alakush to Ensenada): works fine. You finish at the post office, but there are fewer services and minibus options there.
• Half-trail out and back from Ensenada: walk to the first beaches and headlands (1.5–2 hours return). This suits families and anyone short on time.
• Big day, Costera plus Hito XXIV: after the Costera, go to the Lago Acigami car park and add Hito XXIV, which runs to the Chilean border (3.5 km one way, about 3 hours return, flat). That makes a 7–8 hour day.
• Costera plus the Lapataia short trails: finish with Mirador Lapataia, Paseo de la Isla and La Baliza for the “end of Ruta 3” sign.
• Pampa Alta plus Costera: Pampa Alta (4.7 km, about 2 hours, 252 m of gain) runs from Río Pipo to Ensenada through forest, with a Beagle Channel viewpoint. Link it with the Costera for a full traverse of the park.
• Camping: the free camping areas (Ensenada, Río Pipo, Laguna Verde/Cauquenes) are basic and seasonal. Access tickets are valid for 48 hours with a camping permit from the rangers. The status of each campsite is under review for 2026–27, so confirm with APN.

Is the Senda Costera suitable for kids and families?

Yes, for active children of about 8 and over who are used to walking 3–4 hours. Younger children are better off on the first 1–2 km from Ensenada as an out-and-back, or on the Lapataia boardwalk trails. The trail does not suit strollers or wheelchairs. The park’s accessible options are the 150 m adapted section of the Castorera and the Lapataia boardwalks; our park with kids page has more.

Senda Costera vs other Ushuaia hikes

Our take: for a single day, do the Costera if you love coast and forest. Do Laguna Esmeralda if you want the classic Patagonian lake view, and Cerro Guanaco if you want to earn a view from a summit.

Prefer a guide? Trekking and canoe tours

If you would rather not juggle minibuses, a trekking and canoe day combines the Senda Costera with a guided paddle. A guide explains the Yámana middens, the birds and the forest, and transport is handled. These are the listings we checked:

• On GetYourGuide: the Tierra del Fuego National Park Trekking & Canoeing costs from $184 for an 8-hour day, rated 4.7/5 from 78 reviews. The Trekking and Canoeing in Tierra del Fuego National Park costs from $168 and walks 7 km of the coastal path; it is rated 5.0/5, but from only 10 reviews.
• On Viator: the Tierra del Fuego National Park Trekking and Canoeing in Lapataia Bay costs from $184, rated 4.8/5 from 101 reviews, and the Exclusive Tierra del Fuego National Park Hike and Canoe Tour costs from $178, rated 4.8/5 from 88 reviews.

Book the GetYourGuide day if you want the most reviewed hike-and-canoe listing on our site, or the cheaper $168 option if the coastal path itself matters more to you and you accept a short review record. Park entry is usually extra. Before you pay, check the pickup time, whether lunch is included, the canoe route and what the guides walk in October and early November while the Costera is closed. Every option is compared on our hiking tours page.
