My most-repeated day trip. Doable solo, doable in flip-flops (though I wouldn't), and it ends with the best meal you'll have all week.
The garden alone is worth the trip, but Kandy town at night is where things actually get good.
Skip the sit-down places and follow whichever stall near the Clock Tower has the longest line.
The route I actually followed — adjust the pace to however much rain you're willing to walk through.
