"Sulla Collina dei Morti" refers to a well-known cycling climb (Côte du Mort) that connects Jouy-en-Josas to Vélizy-Villacoublay. The name is not related to the elevation gain, but to the woods surrounding the road. It is a shaded and pleasant climb, with a gradient varying between 4% and 6%.

Difficult route if you are there to ride. I do not recommend it to cyclists other than touring cyclists.

A lovely walk reminiscent of the old route of the Bievres Valley. Luckily, we avoided the extension of the A10 to the ring road! A fun route, but watch out for pedestrians and cross streets...

Today we went on a beautiful hike near 🌞 in the Parisian forest. With an area of approximately 846 hectares in the west of the city, the Bois de Boulogne can be considered one of the two 'lungs' of Paris and the second largest green space in terms of area, after the Bois de Vincennes in the east. In October, many cyclamens bloom here along the hiking trail. A hike all the way around the lake with a visit to the island is a wonderful one. A free ferry ride is offered to get to the island. Highly recommended. We took a short break at LE CHALET DES ILES. Afterwards, we hiked a short distance on the island. Surprisingly, the heron was very friendly. I had the impression that it was expecting to be photographed 😄. It immediately struck a pose; I've never been so close to a heron before. There are always great photo opportunities along the hike, with small, babbling brooks in a very idyllic setting.

Bois de Boulogne Paris, France The two trees (240 cm) are a gift from Swedish industry to the Parisians and symbolize love and unity. This bronze statue was inaugurated in 1994. With this donation, the investor – a Swedish industrial holding company – and the Wallenberg family acknowledge the historical significance of relations between France and Sweden. At the tip of the small island in Lake Superior, this symbol of love has become a favorite place for Parisians to rest, row, and contemplate for bird lovers. There are great places to sit and relax. The sculpture is beautiful to behold and highly recommended 👍 to visit.

Another wonderful moment that simply takes you away 🥰. First, we took a break on a wonderful viewing bench and enjoyed the view of the Les Deux Arbes sculpture and the surrounding area 😍. It was hard for us to leave this place 😔. But the day is drawing to a close. This short hike in the Bois de Boulogne 💙 is absolutely spectacular and highly recommended.

The view from across the shore was spectacular, but to see it from here is incredible. To see so much romance in one statue is indescribably beautiful.
