Hot springs through which mineral-bearing super-heated seawater finds its way to surface 750ft up on the mountainside above the town of Soufriere.
Tourist attraction where collecting specimens is definitely not the done thing and the only specimens on offer at the numerous roadside souvenir stalls were small bags of sulphur powder, presumably from the local pharmacy.
The rum is very good, though.
