* The Pitons: These iconic twin volcanic peaks are a UNESCO World Heritage Site and a popular tourist attraction. However, you cannot drive through them.
* Sulphur Springs: This area is known for its geothermal activity and the presence of mud baths and hot springs. You can drive to this location, but you won't be driving through a volcano.
* Qualibou Crater: This extinct volcano is a crater lake, accessible by hiking trails. While you can drive to the trailhead, you cannot drive through the crater itself.
Perhaps you're thinking of a drive-through volcano in another location?
