Actually, he may not have gone to Limasawa island at all, but to Mazaua, at that time a well-known trading town - almost certainly on the coastline at what is now Butuan City. For nearly a century after Magellan, Spanish fleets were still creeping up the coast of Mindanao from the Indies, seeking the fabled city of Mazaua, and all of them failed to get there.  

Just suppose - if after 400 years of colonisation by the Spanish, your country was taken over by the Americans, as spoils after a squabble with the Spanish. They immediately put down a growing independence movement, massacred half a million Filipinos during various 'insurrections', then 40 years later, abandoned the country after just 3 days of Japanese invasion in 1941. Sure, 'General' McArthur came back, fought well, and took over Manila after reducing it and its people to rubble from a distance, and you were 'liberated'. 

Just 92 years after Magellan 'found' the Philippines, a 17th century Dutch mapmaker - (Jadocus Hondius - Amsterdam 1613) managed to map out the whole East Indies. He didn't get it quite right (especially the Philippines), but he did well enough:

Compare this map with the modern one - a bit different. You can see the main islands - Cebu, Negros, Mindanao; Saburan' was Leyte. Just right (4 o'clock) of Cebu is Bohol, and just right (4 o'clock again) are some islands. Maybe one of these is Siargao.

Note the 'Pasaje de S. Clara' - it shows a massive reef. The Spanish were coming from Mexico; when they hit the Philippines (perhaps after stopping in Guam, shown in the old map just a tiny bit east of Mindanao) they had to cast about a bit before 'entering' the islands. Dinagat Sound is reef-fringed. Leyte Gulf (where Magellan happily passed through) is fairly safe. The sailors, reporting back from their voyages, could only describe what they'd seen. They could (just about) tell their latitude (North/South) but it would take another 200 years to get their longitude (East/West) right. Which is why, on the old map, Guam is shown just a spitting distance from the Philippines.

But also note, on the old 1613 map 'SURICA' (position not indicated too well), must have been what is now Surigao City. Maybe 'Malaqua' is now Mabua, a small village just north of Surigao.

' B. de Malcga' may be Llianga Bay, 'G de Refurrei' a prominent gulf on Mindanao's east side, 'C. de Bicay' something similar, but a cape. 'Dapito' must be Dapitan, 'Cavangao' is Camiguin, *indanao is now Maguindanao, 'Bicaia' now Davao City, etc. 'Sarangan' is a very small island (Sarangani) off to the south of the Philippines, but all those other islands shown near it ('Candinago', 'Talaon', etc) are miles & miles away. 'Matuo al Cabino' and the chain of islands shown south of it just don't exist.

Down to the left are 'Tagima' (Basilan?) 'Solor' (Jolo), and the chain (or jumble) of the Sulu Islands, including 'S.Joana'. The Spanish never really colonised the Sulu islands, nor did the Americans (although they committed some very nasty atrocities), and to this day, the islands are reputed to be a bunch of pirates, etc. There are some 'Abu Sayyaf' gangs, kidnapping 'whiteys' or Chinese for money, but this is a very old-established criminal custom, and nothing whatsoever to do with the 'War on Terror'. (You might as well classify an old time Cockney burglar as a 'terrorist'.)

I am grateful, as usual, for the source of the old maps, to:

Alegre, Edilberto N. Kinilaw: a Philippine cuisine of freshness

by Edilberto N. Alegre & Doreen G. Fernandez. - Makati, Metro Manila: Bookmark, cl991

This is a very good book, indeed, about a type of cuisine you may never heard of.

I shall be plagiarizing it shamelessly in this website, so I am more than happy to give them full credit & thanks.
