Grande Rota do Oeste is Terceira's long cross-island route, tracing the whole western end of the island from one forest reserve to another. Along the way the landscape shifts constantly: managed recreation areas, patches of semi-natural forest, open coastal cliff tops and stretches of high mountain ground, each with its own character.

The route runs from the Forest Reserve and Recreation Park of Lagoa das Patas to the Forest Reserve and Recreation Park of Mata da Serreta, and it is officially split into two stages of about 21.9 km and 9.3 km. Walking it in one go or breaking it across two days both work; pick whichever matches how much daylight you have.

This is rated a hard route and covers roughly 31 km with an official walking time of about ten hours and roughly 1,400 m of climbing and 1,700 m of descent along the way, so most people treat it as a two-day outing rather than a single push. The distance and the exposed, varied terrain are what make it demanding, not any one obstacle.

Wild camping isn't allowed on Terceira, so anyone splitting the route overnight should book one of the local lodging or rural tourism places on the west side of the island ahead of time. Carry enough food, water and extra layers for a full day out, since there's a long stretch between any kind of shelter.

What to know

Start & finish
Lagoa das Patas to Mata da Serreta
Safety
This is a long, demanding route that can take most of a day even for fit walkers, so start early and don't underestimate it. The coastal cliff edges and the exposed mountain stretches turn genuinely hazardous in fog, wind or rain, so check conditions before setting out and be ready to turn back.
When to go
The trail is walkable all year, but the open coastal and mountain sections are most comfortable in the drier months, while wet weather makes the forest stretches muddy underfoot.
