We have an island family in Siargao who has a surfing school called Agudo surf, which we would recommend if you fancy some surfing. A lesson would cost P1,500 (£21-£22) per session for two hours which also includes your longboard rental (or a shortboard, if you're a pro!) plus a boat ride fee of P150 (£2-£3) per head to the surfing spot, if needed, depending on the tides. Let us know if you want yourselves booked in!
We're working on organizing a 24 person capacity pump boat for the islands tour, available n a first-come, first-serve basis, costing around P1,800 (£25) per person (including food). There are also smaller boats offering island tours, and you can arrange food at Daku island for P1,400 (£20) per person. If we don't have 24 people, we'll go with the smaller boat option.
