Patagonia,
Trek.

Overview

Today is mostly about getting into position. The bus from Punta Arenas takes about three hours, tracing the pampa where guanaco graze in loose herds and rhea sometimes bolt across the road. Once in town, Erratic Rock's 3pm talk is the real start of the trip logistically: it covers trail conditions, water sources and how refugio bookings actually work on the ground, which matters more here than any guidebook. The evening is unhurried, a walk along the Costanera as the Seno Ultima Esperanza flattens out at dusk, then a proper bed at Hotel Costaustralis before the trek begins.

Tips

Late August is still winter in this part of Patagonia, with days often no warmer than 5 to 8°C and a wind that cuts through anything less than a proper shell layer. Wear real hiking boots on the bus, not trainers, since gear checked as luggage sometimes goes missing between Punta Arenas and Natales. Bring layers you can add and strip through the day: base layer, fleece, windproof shell. Tomorrow's first stop is the bus to Pudeto, so pack your trek bag tonight rather than in the morning.

Getting around

Puerto Natales itself is small and entirely walkable. Erratic Rock is a few minutes from the centre, and it's a four minute walk from there to the Costanera, then another fourteen minutes along the waterfront to Hotel Costaustralis. No taxis needed today.

Local tips

Gear shops cluster around Erratic Rock and along Baquedano, so this is the place to rent a stove, sleeping bag or trekking poles if you didn't bring your own. Cash still matters here: some refugios and smaller shops don't take cards, and ATMs in town can run out on busy weekends. If you haven't locked in refugio or campsite bookings inside the park, do it tonight, availability tightens fast even in shoulder season.

Overview

Today is the out-and-back to Grey Glacier's viewpoint, the reason most people add an extra day at Torres del Paine. From Refugio Grey, where yesterday ended, it's a steep hour north over two swaying suspension bridges to Mirador Grey, with the ice face stretching out below Paso John Gardner. Lunch is back at the refugio dock, with an optional boat or kayak trip among the icebergs if the wind cooperates. Then comes the long walk south along the lake to Refugio Paine Grande, arriving just as the wind picks up on the exposed ridge above Lago Pehoé.

Tips

• Mornings on this stretch sit around 2 to 5°C, and the return leg's wind can knock the felt temperature down further, so keep a windproof layer handy rather than packed away.
• A buff or hood earns its keep on the last few kilometres into Paine Grande, where the wind comes in side-on.
• Trekking poles help both on the steep bridge section and on tired legs later.
• Fill water bottles at Refugio Grey before setting out. There are streams along the way but no proper refill point until Paine Grande.

Getting Around

Everything today is on foot, around 22 kilometres round trip with roughly 400 metres of climbing on the morning half. The trail to Mirador Grey is clear but narrow in stretches, and the suspension bridges take one person at a time. The return south follows yesterday's lakeside route, so the ground will feel familiar, just longer and windier by the afternoon.

Local Tips

Boat and kayak trips from the Refugio Grey dock run purely on wind conditions and are usually confirmed that same morning rather than booked in advance, so ask at the refugio desk early in the day. Tomorrow turns inland towards Campamento Italiano and the French Valley, a change of pace after two days spent along water and ice.
