Can you easily visit the Peradeniya Gardens on a day trip from Colombo?

Visiting the Peradeniya Gardens on a day trip from Colombo is absolutely doable and also pretty common, with around 2.5 to 3.5 hours of travel time in each direction, depending on traffic and stops.

The easiest and most comfortable option is booking a seat on the early morning intercity express train from Colombo Fort straight to Peradeniya Junction station. As another choice, you can hire a private taxi through the Central Expressway, then reach the gardens by late morning, spend about three hours wandering around, and head back to the capital with plenty of daylight left before dinner.
