Located on a hill in the north, the Bastille affords some of the best views of Grenoble and is an ideal place to watch the sun rise and set over the city. Though the entrances through the parks at the Bastille’s base are locked and inaccessible outside of business hours (rendering them unusable for hikes up to see sunrise and sunset), there are several routes and trails up the hill to the Bastille. You just have to know where to look.
Should you plan on doing a sunset or sunrise hike, bring a light, since there are few lights along the Bastille trails. Second, bring water. The Bastille hill isn’t that tall but some of the trails up can be steep, and the only source of water I saw were fountains at the top where the “bubble” gondolas depart. Third, bring a windproof jacket. Even when the air in the city below is still, it whips and chills at the top of the Bastille walls.
If you’re coming from the part of the city just south of the Isere River, the easiest route up to the Bastille is at the southwest end of Rue Saint Laurent. Look for the Fontaine du Lion, a massive fountain depicting a lion battling a snake; there are stairs just south or a bit north of this fountain that will take you to a trail that leads up to the Bastille.
I’ll try to get an actual trail route up here later, but for now the best instructions I can give are to stay to the left to avoid the road, and keep looking for stairs or switchback trails leading up. After 10-20 minutes you should reach the first Bastille walls with stairs leading up into the ruins. Walk up the stairs and continue climbing, but any tree-free outlook after this point should provide a good view of the city.
At the top of the Bastille you’ll find a lookout point and the “bubble” gondola that can take you back down to the city (11 AM – 6 PM). Enjoy the views, and then climb or take the gondola back into town.
