Due to a landslide on the past weekend, in a position about 1 km down from the Pico Ruívo mountain hut, the Pico do Areeiro-Pico Ruívo mountain trail (PR1) - the most important of the island - is closed to hikers.
And since the landslide happened in a position already near the end of the trail (if you are arriving from Pico do Areeiro) and well after the tunnel that divides the route into two, this, now, makes the trail totality impassable.
Hopefully, the government responsible persons are aware of the problem and already adopting an active attitude (the sooner, the better) towards the resolution of the situation.
After all, this is only the most important mountain trail in a island with nature tourism as its most important asset.
