clear water, bright routes
island hopping in thailand in the southern region is built around short distances, structured loops, and islands that sit close enough to visit in one day
the south gives you real movement because everything is only a few minutes apart
how the routes work
short distances, fixed loops, predictable timing
most southern trips follow a simple pattern

visit 3 to 5 islands
spend 30 to 60 minutes at each stop
return around 3 pm
