## Lake Seine: Parisians' private cold jade, rowing into the parallel universe of the Jurassic
**Is it worth going? ** If you are tired of the flood of tourists, this is the respirator of Normandy! The Lake Seine (Lac de la Seine), 1.5 hours' drive from Paris, is actually the **Canal Saint-Martin Reservoir** - but don't be fooled by the name, it is the illegitimate child of geological miracles and French pastoral, so beautiful that the locals keep their mouths shut.
### Hardcore highlight: Inception under the chalk cliff
* **Rowing through the Cretaceous: ** Rent an electric boat (€20/hour) to break into the center of the lake, **30-meter-high snow-white cliffs** suddenly rise from the ground. Touching the cold rock formations with your fingertips, it is a history book pressed by the bones of marine microorganisms 75 million years ago, and the gullies washed out by rainwater are like the ribs of giant beasts - **Parisians are actually having a holiday picnic in the dinosaur cemetery! **
* **Ghost Dance at the Sunken Church:** The **Saint-Vigo Church**, which was submerged in the 19th century, lies quietly at the bottom of the lake. When the water level drops in midsummer, the spire of the bell tower pierces the lake surface. When paddling close, the oars will startle a flock of bronze waterfowl, as if the dead are flapping their wings.
* **Rainbow Mast Forest:** At the **Gailard Castle Pier** on the south bank of the lake, the masts of hundreds of sailboats pull out golden lines in the sunset. Sit in the old tavern next to the sluice and watch the boat owners use the pulley system to "hang" the yacht over the dam - **This is the magical operation of the living fossil of the Industrial Revolution**.
* **Dark Night Starlight Bathing Beach:** Avoid patrolmen (shh!) late at night and jump into the shallow waters of the bay. The chalk rocks reflect the moonlight, and the water body flashes with blue phosphorescence - the **natural fluorescent party** of algae and minerals is more magical than Mont Saint-Michel.
### The cool tricks that only locals know:
* **Picnic Assassin Equipment:**
- Buy **Apple Cider Sausage** at the bakery in Les Trois Lacs
- Spread the tablecloth and choose **Elephant Trunk Hill Grotto** on the north shore (Google "Grotte d'Eawy"), where the echo of the rock wall amplifies the sound of champagne bottle opening
* **The ultimate Easter egg for anglers:** Rent a fishing rod (€5) and wait downstream of the sluice, **2-meter-long European catfish** tumble in the turbine vortex, biting the hook with the force of a small sea monster.
* **Ruins exploration code:**
- Abandoned **Freine Steam Station** (Chemin des Écluses), rusty valves engraved with 1887 worker graffiti
- **German bunkers** on the west side of the reservoir, wild roses growing in the bullet holes in the wall
### Fatal warning:
Dry season (August-September) the lake surface shrinks by 30%, and the white cliffs are exposed like the corpse of a giant whale; in the flood season (April-May), be careful of underwater broken trees when rowing - last year three canoes performed "Titanic" here.
When you bite off sour bread with Normandy cheese in the chalk cliff cave and watch the sailboat slide past the reflection of the church spire, you will suddenly realize: Parisians use the Jurassic cliffs as their backyard
