What Travellers Say
Reviews Summary
Visitors find the Bastille caves to be a unique and worthwhile addition to their trip to the Bastille, appreciating the natural formations and historical aspect. However, the steep, slippery steps and limited natural light are common points of caution, making preparation with good shoes and a flashlight highly recommended.
"Worth a visit, best to visit in the morning while there is more light. Perhaps bring a torch. Steep steps down if you are mobility impaired. At the end you can double back to the Bastille on a footpath if you do t want to climb back up al those stairs!"
Boaz Kirschenbaum
"Visiting the cave was the best part of going up to the Bastille. It’s pretty small but still it’s a unique attraction which is not very common in other places. Nothing special inside but it’s nice to walk inside of the cave, it’s probably around 200 meters long and has some stair inside"
Alexey Subach
"Great cave you can complete in about 15 minutes to each end. A lot of loose rocks and dripping water so can be slippery especially the steep stairs. Some of the steps are uneven too."
