Umpherston Sinkhole is a gobsmacker! Nothing like it for size, grandeur and uniqueness. The story of this amazing attraction is posted for all to peruse. My grandkids LOVED the (very fat!) possums that emerge each night for a free feed. A local told us that they love bananas; and this was evidenced by the "theft" from a hand of a very large banana! A truly stunning natural feature well worth a visit.
