The collapse, despite its few meters, a mix of hiking and carrying that raises the heart rate of even the most experienced, always offers one of the most picturesque views of the Madrid region near the capital: the confluence of the Manzanares and Jarama rivers, the Presa del Rey, a privileged panoramic view over parts of Rivas and Arganda, facing the mountains where much of the Battle of Jarama took place, and of course the cliffs. Having passed by there many times, it never leaves me indifferent.

An immense collapse of the Rivas cliffs has created a wonderful viewpoint at the confluence of the Manzanares and Jarama rivers. It is worth having to push the bike in this section, since it is impossible to ignore the panorama.

The plant cover that adorns the steep earthy slopes of the Jarama Valley is an exhibition of ingenious botanical adaptations to survive in the gypsum aljezares characteristic of the fertile plains of southeastern Madrid. The esparto grass forms large clumps of long, smooth leaves with a very dense and closed stump that retains moisture inside. The austere jabuna has a woody bearing, the stems are very fine and it does not exhibit bright colors that require high energy consumption, except in the flowering period. Another common plant of the cuts is the ontina or mugwort, used in popular medicine as an antidiabetic, vermifuge and invigorating, it develops thorns and discreet colors to avoid excessive perspiration. One of the most striking plants is the reseda, which has long, twisted stems. There are also thyme, scaly rosemary and harmaga, which defend themselves from the xerophytic environment with a reduced foliar surface and scaly leaves.
