Ultimate Guide to Once Islas: Island Hopping in Zamboanga

Share this:

Attention, nature & beach lovers! Zamboanga City has opened a new attraction and it is great: Once Islas.

Once Islas is a new eco-cultural tourism attraction which opened to public last July 2018. It is composed of 11 islands along the Moro Gulf, which belong to the barangays of Panubigan and Dita in Zamboanga del Sur. Of these islands, 4 are opened to the public and can be reached by registering at the office of Barangay Panubigan. These are Bisaya-Bisaya, Sirommon, Baung-Baung and Buh-Buh. The first three are ideal for swimming and snorkeling, while the last one is for cultural touring.

We visited Once Islas as part of the fam trip for Zamboanga Hermosa Festival 2018. As a beach lover — you know we mostly cover beaches here in our blog — I was beyond excited to set foot in Once Islas.

Our island hopping tour in Once Islas

We attended a short orientation in the barangay hall for the island hopping, and then we walked to the port where there were boats waiting for us. At this moment, I knew that it’s going to be good because even the view there was great — we were facing an island with deep-green water, lots of trees and, on the other side, a picturesque seaside community.

Bisaya-Bisaya Island

The first island we stopped by is Bisaya-Bisaya Island. It has pristine white-sand beach and deep-green water. There’s lots of coconuts among other trees.

I love that it’s so clean! The LGU brings garbage bags so guests won’t have to leave their litter in the island.

We trekked to one side of the island with the tour guides to see rock formations. Then we went to have fresh buko (because all great beach escapades include fresh buko).

Some people went swimming, some went kayaking. The water was nice and warm, and you can snorkel not far from the shore. There’s tons of corals and fishes, but it isn’t as lively as other snorkeling areas I’d been to. Still, it adds on option on things to do if you ever get tired of swimming.

When it was low tide, we crossed to the adjacent islet (our tour guide Errold said it’s still considered part of Bisaya-Bisaya Island) where there’s a natural pool. A little small, but perfect for that Instagram photo. (Read also: Natural pools in the Philippines)

On our way to the next stop, we saw other islands and again there were some nice views. People are usually focused on the stops, but one thing that I enjoy about island hopping is passing by unknown islands as well. Here’s one of locals picking up shells (I assume) when it was low tide.

Sirommon Island

Our second island hopping stop was Sirommon Island. Sirommon Island is known for its sand bar.

What we did first is trek for about 5-10 minutes to get to the other side of the island where our lunch was waiting — a boodle fight consisting of fresh seafood like tuna, crabs and squid as well as pako (seaweed) and fruits. Yum yum yum. It’s one of the best meals I had during our one-week trip to Zamboanga.

Sirommon Island is the best place for snorkeling & diving in Once Islas. It was, however, low tide during our visit and we didn’t bring our own snorkeling gears.

After lunch, we went back to the main beach area and stayed at the sand bar. The sand bar is home to numerous star fishes. It reminded me of Candaraman Island in Balabac. Anyway, I’m calling this Starfish Sand Bar. The water here is warm and cold in some parts. It’s also a great place to chill, I wished we had more time.

Buh-Buh Island

We didn’t stop by Buh-Buh Island, but we had a glimpse of its mosque.

Baung-Baung Island

Our last stop was at Baung-Baung Island. Again, it has white-sand beach and good for swimming. There’s also an option to trek for an overlooking view of Bisaya-Bisaya Island. The trek takes 248 steps, but it sounds more intimidating than it is — it probably takes no more than 10 minutes to reach the view deck. And the view is really worth it!

Regretfully, we were only in Once Islas for a whole afternoon — and I’d learned that currently only day tours are allowed. Even though I was able to swim, snorkel, trek, eat snacks and lunch, it still felt a little too short to spend in these pristine islands. Oh well, there’s always a next beach vacay.

How to get to Once Islas

Once Islas is located about an hour away from the city proper. Here are the commute directions:

  • Head to the integrated bus terminal. From there, ride a north-bound bus bound for Pagadian or Ipil and get off at Panubigan crossing.
