La Gomera mist, and as a result are covered in lush and diverse vegetation: they form the protected environment of Spain's Garajonay National Park, which was declared a UNESCO World Heritage Site in 1986. The slopes are criss-crossed by paths that present varying levels of difficulty to visitors, and stunning views to seasoned hikers. The central mountains catch the moisture from the trade wind clouds and yield a dense jungle climate in the cooler air, which contrasts with the warmer, sun-baked cliffs near sea level. Between these extremes one finds a fascinating gamut of microclimates; for centuries, the inhabitants of La Gomera
La Gomera the subsequent immigration, genetic footprints of the first settlers of the Canary Islands persist in the current inhabitants. Parallelling mtDNA findings (50.1% of U6 and 10.83% of L haplogroups), the largest average Northwest African contribution (42.50%) was found for the samples from La Gomera. According to Flores et al. (2003), genetic drift could be responsible for the contrasting difference in Northwest African ancestry detected with maternal (51% of Northwest African lineages) and paternal markers (0.3–10% of Northwest African lineages) in La Gomera. Alternatively, it could reflect the dramatic way the island was conquered, producing the strongest sexual asymmetry in the
