By Raquel Mustillo GEOTOURISM has become the domestic travel smash hit of the holiday season with record numbers of visitors descending on two of the Limestone Coast’s most spectacular natural sites. The Tantanoola and Naracoorte Caves are becoming fan favourites of intra and interstate tourists to the region, with tours quickly reaching capacity each day. National Parks and Wildlife Limestone Coast manager Nick McIntyre said preliminary figures indicated visitation was up 25pc at both sites compared to January 2019. Mr McIntryre said while the true figures would be confirmed at the end of the month, initial reports suggested a significant increase from last year, which he described as “a very, very good year”.
