My girlfriend and I went to Carnaza Island on the 1st week of May and we really had a blast. the place is stunning!

and we also got the chance to see Lamanok island too. all these trips and travels cost us only 1,499 pesos. From bus fares to boat fares and accommodations. I hope this can be help for you guys if you are planning on traveling to Carnaza Island.
