Climb to the top of Spain! Mulhacén is the highest mountain in mainland Spain, towering 3,479 metres above sea level, so it’s not surprising that it offers amazing views. If the weather is clear, you can see right down to the Mediterranean Sea. The landscape is mainly rocky and barren, but many of the plants that do grow here are unique. You are also very likely to see ibex during your walk. This circular route also includes the crater lake Laguna de la Caldera and the Mulhacén river.
