Take advantage of your time in Trás-os-Montes to get your adrenalin pumping. There’s no need to bring equipment - there are plenty of places you can rent from. All you need is determination.
In the middle of Serra do Alvão, make a canyoning descent of the river, blending the best of abseiling, swimming and walking.
Go sliding and climbing, or take the easier option of an off-road jeep tour of these wonderful surroundings.
Meanwhile, if you’re the type who prefers activities to be more peaceful, go hang-gliding. Soar through the skies far above the hills with the greenery and the dark schist and granite below.
