    Sydney Dive Site Hints
    "The SS Tuggerah is Sydney's best wreck dive"
    Mainit Bubbles Spring Point
    Michael McFadyen's Scuba Diving - Mainit Bubble Springs Point, Philippines

    In August 2023 I did a three week long dive trip to the Philippines with my friend John. We spent the first week at Anilao staying at Buceo Anilao Dive Resort.

    There are dozens of dive sites located within 20 minutes run from the resort.

    Unfortunately we had a Super Typhoon hit the northern Philippines when we were there, so the Coast Guard banned all boats and diving later in the week. This dive site was one we visited on the first day when we arrived, so the typhoon had not impacted yet but it was already a bit windy. This site was mostly protected from the wind.

    Mainit Bubble Springs Point (or just Bubble Springs) is located about 1.6 kilometres from the resort around the point of the peninsula. A GPS mark for the dive spot is 13° 41' 19.320" N 120° 53' 57.527" E (using WGS84 as the datum).

    When we arrived at Mainit Bubble Springs Point, there were a few other dive boats there, one of the few times we had other boats near us. Unfortunately, my camera had a flat battery sure I charged it before leaving home), so I have no photographs from the dive.

    The dive site consists of a shear wall that runs for about 70 metres or so and drops from 22 to 30 metres. bommie that breaks the surface off the southern point of the peninsula. The dive boat anchors a short distance to the west of the wall in about nine metres of water.

    Once we enter the water we head down the slope to the east. This is where the site gets its name from. There are bubbles coming out of the sand and they are warm as is a small amount of water escaping from the sand. It is obviously from some sort of volcanic activity (there is an inactive volcano 35 kilometres to the north-west. The bubbles are quite widespread.

    From here we come to the wall which is very nice with gorgonias, sponges and sea whips on the coral. We are now at 22 metres and we drop to almost 30 metres as we go along towards the north. We see quite a few nudibranchs, a yellow-spotted boxfish and a banded-sea snake. There are plenty of different sorts of shrimps and some anemones and clownfish.

    After the wall ends, we come back up the sandy slope to the top of the reef at 20 metres and gradually get shallower as we head back to the boat across the top. We see more interesting things on the way.

    After almost an hour, we are back under the boat for our safety stop. This was a really good dive. Water temperature was 28C in August but the visibility was only fair, the worst of our dives here.good, around 10 to 12 metres.
