Bauduen Observatory

The Observatoire Astronomique de Bauduen, on the southern end of the Lac de Ste. Croix, offers observation of the distant stars and our own nearby sun as well as discovery classes in geology, botany, photography and spelunking.

The location is beautiful and handy. At the extreme southern end of the Lac de Ste. Croix, the observatory is just across a small inlet from the village of Bauduen, on the D17 road. It's from over here that you'll find the most picturesque view of the village.

The lake itself is a great vacation place, and there is a camping site on the D17 just across the road from the observatory. The northern end of the lake is next to two beautiful and famous visiting spots for this part of France: the Grand Canyon du Verdon and, 7 km to the north, the village of Moustiers-Ste-Marie.

Night Viewing

  • A three-hour night of astronomy begins at 21:30 during the summer. Winter viewing is on Saturday night at 21:00, dependant on the weather.
  • An all-night "stage" (course) in astronomy is also offered, and the price for 1995 was only 150 francs. [Yes, it's been awhile; probably around 30 euros now.]
