One of my favorite memories in Tenerife (tied with hiking Mt. Teide) was biking to a local beach. Europe is apparently very biker/walker friendly as there is a wide sidewalk that stretches for miles along not only local roads but the busy highway as well. Kelly, Leah, and I loaded our backpacks and biked about 6 1/2 miles along the highway to the beach. The ride was breathtaking--the cliffs of the mountain to our left and crystal blue ocean to our right.
