On the lookout for lynx
The Iberian lynx is so rare that few people ever spot one, but a new tour run by Nature Trek (naturetrek.co.uk) hopes to let you see this magnificent beast. The lynx's last refuges are the remote corners of Coto Donana and the rugged regions of the Sierra Morena. Even if you don't glimpse a lynx, you should see other mammals, including otters, wild boar, and red deer.
A six-day tour to the lynx's habitat with Nature Trek costs £795 per person, based on two sharing, including return flights, accommodation, food and guides.
