Most travellers reach Donsol through Legazpi, the main transport hub for this part of Bicol. Vans and buses connect Legazpi with Donsol, usually taking around 90 minutes depending on road and weather conditions.
The whale-shark boats leave from Dancalan, a short tricycle ride west of Donsol town centre. Stay near Dancalan if the boat trip is your main reason for coming, but carry enough cash: card use and ATMs are limited.
