It’s at Lotofaga, not Lalomanu
The Samoa Observer for Wednesday 03 February 2016 under the title Tourism –Pages 18-21 had this heading –The Best of Samoa- listing the To Sua Pool at Lalomanu-Upolu Samoa.
For the sake of records - the Toa Sua Pool is at Lotofaga and not Lalomanu.
May be its best for Mr. David Johnston of the CNN to check his information by asking the right people! Fa’afetai.
