The blanket of cloud is an amazing natural effect created by the trade winds as they push the clouds up against the mountains on the north of the Island, producing what looks like a soft fluffy blanket when seen from above. This horizontal mass of stratocumulus forms naturally at altitudes of 500 to 1,500 m (1,640 to 4,920 ft).
It makes for a breathtaking sight which visitors can see in 3D. This means that when starting their climb, visitors see the blanket from below; next, they journey through it on their way up; and finally they see it from the above, with the sun shining down on it, concealing the lower parts of the Island. On days when this natural phenomena does not occur, visitors will be rewarded with a bird's-eye-view of the Island, which is also a wonderful way of discovering Tenerife's scenery.
