We've been wanting to visit the Southern Islands of Singapore, and finally made it 2 weekends ago.
Away from the usual weekend crowds, St John's Island and Kushu Island give you a chance to see Singapore from a different angle. Attracted by the rare sea creatures of the former Island and the clean water and sand in the latter, we ended up spending most of the time near the shore instead of exploring the islands.
We were not geared for swimming, but the fun thing was the spontaneity of it all - from being allowed to wade in the water to swimming naked (only SW). This was so the kids did not dirty their clothes. Fortunately, we brought food for picnic as there were no food stalls around. If it wasn't because we were all starving, we would have stayed longer, because the ferry tickets were not cheap - S$15 per adult and S$12 per child!
