Worth it if you've got a few hours and don't mind paying entry—the near-perfect rating from nearly 35,000 people suggests this limestone karst boat trip genuinely delivers. Go early morning to dodge the tour groups that flood in by midday, and book direct rather than through Viator's 874 options, which will likely just add markup to what's already a paid experience.
