In the hollow of the valley, a small stream meanders, feeding many ponds and a waterfall. Perfect for recharging your batteries. This arboretum is sumptuous. You will find incredible tree species, sequoias, eucalyptus, magnolias, giant bamboos and an alley planted with absolutely remarkable tree ferns. On the water, a beautiful diversity of birds, cormorants, herons, egrets, ducks, and kingfishers among others. Good walk a stone's throw from the beach and the marina of the marina.

In the heart of the Vallon du Stang-Alar, the Botanical Conservatory garden is nestled in a former quarry. The 30-hectare site was chosen for its mild climate, steep slopes and the presence of water, which make it an exceptional place where plants from all over the world can be grown. The site is crossed by wide and narrow, stabilized paths, as well as forest trails. Opening hours Conservative garden: open every day from 9:00 a.m. to 6:00 p.m., until 8:00 p.m. in summer.

Moulin Blanc beach is the only fine sand beach in the city of Brest. It was developed over the last century to offer Brest residents a vacation spot close to the city.

Nestled in the breathtaking landscape of Brest, it towers majestically above the Élorn - the Pont de l'Iroise. Its impressive silhouette, spanning the river between Le Relecq-Kerhuon and Plougastel-Daoulas, offers both locals and visitors an impressive perspective of the region. As you cycle across the bridge, you are accompanied by a magical panorama: If you look inland, the scenery opens up to a picturesque interplay of land and water. If you look to the other side, your eye will be rewarded with an unforgettable sea view. The bridge is a gift for cyclists. Here, in the flatter part of Brest, cycling is particularly pleasant. There is also a wonderful view of the city from here. The technical specifications of the Iroise Bridge are also remarkable. Located on the RN165, which connects Brest and Quimper, it is one of the most impressive cable-stayed bridges in France. It ranks in the list of main spans just behind the famous Pont de Normandie and the Pont de Saint-Nazaire, but ahead of the imposing Viaduc de Millau. But it's not just their size that makes them a highlight in the region. Photographers particularly appreciate the smaller bridge, which is closed to cars. From here you can capture the imposing Pont de l'Iroise in all its splendor.
