Peru is well known for its diversity, with the much-quoted triumvirate of Coast (Pacific), Mountains (Andes) and Jungle (Amazon) only providing a hint at the number of distinct eco-systems within her borders. To get an intense feel for this diversity, Peru North can recommend making the drive from Tarapoto in the department of San Martin, to Chiclayo in Lambayeque, on Peru's northern coast. And who better to have at the wheel for a journey as intensely spectacular as this, in the company of one's parents, than a driver called 'Elvis'. (This was not a nickname.)
