    Guided Walking Week April 2016

    Dates: April 30th-May 7th 2016

    Location: Abdet, Costa Blanca

    A week of guided walking in the mountains around Abdet. Highlights include the climbing of Valencia's highest summit (Sierra de Aitana), traveling completely around the impressive Puig Campana, and several explorations in the Sierra de Aitana. Ancient trails lead through spectacular canyons(峡谷) to abandoned settlements situated high in the mountains. You will discover the snow trader routes which lead from the incredible snow holes high in the mountains down to the villages and towns on the coast. These years, golden eagles have made a return to this area, and you may also see other animals—wild goats, foxes, wild pigs and red squirrels.

    As part of the week you are invited to help clear some local walking paths. This involves clearing collapsed (坍塌的) walls and rocks, cutting back fallen trees. This is of course optional and is just for half a day, it's actually great fun!
