El Retamar is a high mountain pass at an elevation of 2.100m (6,889ft) above the sea level, located on Tenerife in the Canary Islands, Spain. It's one of the highest roads of the country.
The road to the summit is called TF-21. It’s asphalted but includes some really steep sections (up to 11.9%). Heavy snowfalls can occur anytime, being extremely dangerous due to frequent patches of ice.
