We arrived back in Singapore after our winter break in Florida with a week before school started again. We used the opportunity to explore our home a little more and took a ferry out to the Southern Islands. It takes about 45 minutes to get to St. John's and the ferry ticket (round trip) was $15 SGD.
Typically, there are basic summer camp style vacation rentals on St. John's but they are closed for now due to COVID. St. John's used to serve as a quarantine island for cholera and then leprosy, then a penal colony, and even had a drub rehab center in the 1950's. It still has a detention center for illegal immigrants as well. Some local legends even say it's haunted and with such a storied history, it wouldn't be a surprise!
We arrived at the dock at St. John's and had a picnic lunch on the largest beach on St. John's. There were plenty of tables and lots of shade, a precious commodity in Singapore. There are no services on either island except restrooms with showers. We quite liked this as it added to the laid back nature of the place. All of the other beaches in Singapore we've been to have bars, restaurants, bike rentals, etc and can get really busy on the weekends.
