We flew Manila to Puerto Princesa, did the Underground River, then El Nido and Coron. Flew to Cebu for Kawasan canyoneering and a Bohol side trip, then ended in Siargao for the surf-town vibe.
Grouping by region kept the flights down and we never backtracked. Two weeks felt right — enough to slow down in each place. We booked the inter-island flights early; the day-tours we sorted on the ground.
