If you've got some time before or after taking a bath (if you're staying the night, for instance), you might like to sample some of Poring Hot Springs' other attractions. The butterfly farm above the baths is nice, with lots of flowers and several species of butterflies, including the Raja Brooke's birdwing. First, you enter a display area, which has displays of the butterflies and other insects mounted under glass. You walk through this and then enter the butterfly enclosure.
Take your time in the enclosure as new butterflies constantly materialize before your eyes.
