Acro'Liane is an eco-adventure treetop park set in the heart of the Bois Farjon, just three minutes from the centre of Boulogne-sur-Mer in northern France. The park offers four aerial courses for adventurers aged 6 and over, plus a dedicated children's trail and two orienteering courses, all woven through a coastal woodland atmosphere evoking the sea with nets, barrels, and inflatable buoys as décor. Highlights of the courses include zip lines, monkey bridges, Tibetan bridges, a suspended bike, a suspended surfboard, and an exhilarating 11-metre leap into the void. Sessions are run in three daily time slots, and a continuous harness system ensures safety throughout. Admission is priced separately for adults and under-16s, with group discounts available. Acro'Liane is an inviting outdoor adventure venue for families, school groups, and thrill-seekers visiting the Opal Coast.
