Madeira has a vaste network of irrigation canals,
called levadas, that run for 2150 km over the island. Most levadas have
paths or wide rock walls that follow alongside, making the mouintainous
island much more accessible for hikers and walkers. You really should
make time for some walking or hiking on Madeira's levadas! Many guide
books describe the most popular walks in detail. Note that although the
trails along the levadas are well-marked, the terrain is often
precipitous!
