The hayedo Montejo beech forest is included within the limits of the the Sierra del Rincón Biosphere Reserve. This short video (in Spanish) shows some of the sceneries, lifestyle and places to visit.
Among the huge beech trees, with some over 20 meters high, you can also find oak, wild cherry, hazelnut, birch, holly, heather and rowan. Some of the iconic beech specimens have even been named such as la Primera (the first), el Trono (the throne), la Ancla the (the anchor) but perhaps the most admired is la Roca (the rock) which is aged at more than 250 years.
The forest is a haven for many insects, birds and other animals and nearly 100 species of butterfly have been recorded in the area.
