Whale sharks is the reason people come to Donsol. The supposed whale shark spotting season is from December to May. Basically the times when it isn’t raining yet. I went in the middle of May and still saw whale sharks.
I stayed in the Vitton resort, but all the others looked alike.
Do go on the firelfy tours at night. You will see whorls of fireflies that you’ve never seen fireflies do before. You’ll also see the night fishermen with their old school basket and torches. Authentic cultures.
Don’t take the bus to Bicol. I highly recommend you just fly to Legaspi via Cebu Pacific. If you catch it on sale on the website, you can get it really cheap. Eventually there will be a train to Bicol, but it looks like this will still take some time.
In Legaspi, you will be able to see the fabled Mayon volcano with it’s perfect cone.
