DIY Guide to Biri Island Rock Formations (Northern Samar)

Share this:

The Biri Island Rock Formations is one of the best places you can visit in Northern Samar. We went here during a week-long road trip to Leyte. Here’s our experience + travel guide to Biri Island Rock Formations in Samar!

Biri Island is a municipality in northern Samar. The island itself is located along the path of storms, which resulted in rugged landscapes.

There are seven rock formations in Biri Island (Magasang, Magsapad, Macadlaw, Puhunan, Bel-at, Caranas and Pinanahawan). These were formed some 20 million years ago from the movement of tectonic plates and then molded by crashing waves, winds and storms. The rock formations have distinct looks. For instance, Bel-at and Caranas feature smooth limestone formations and natural saltwater pools, while Magasang features pockmarked formations.

All the rock formations are accessible by foot during low tide.

Our trip to Biri Island

From our resort in Bani Island, we took a boat to Biri Island. Once we arrived, we went straight to the tourism office for registration. We were assigned habal-habal tour guides that drove us to the jump-off point to the rock formations.

Since we were there for a day trip, we only scheduled to see Bel-at & Caranas and Magasang rock formations, which are the most visited spots. Our tour guide Kuya Louie said that we would need 2 days if we wanted to explore all the rock formations, as well as do other activities including surfing.

From the jump-off point, we walked across a boardwalk trail surrounded by mangroves and other shrubs to Bel-at & Caranas.

Bel-at & Caranas rock formations is one of the most recognizable spots in Biri Island due to the picturesque saltwater pools formed between limestone formations. Bel-at & Caranas are connected, so most tourists simply refer to the area as Bel-at.

Once we got here, we immediately noticed people swimming on a huge tidal pool. I initially thought that it was the beach area since it was high tide. We took pictures here and then climbed up some low boulders to take pictures of the ocean.

I would like put some nice poem here. Okay, here goes.
“We fall in and out of love in every one of these stories. I feed you dandelions. I eat honey off your back. We hold hands like we are going to fall off the edge of the universe together.” – Azra T

We then explored the limestone formations which are reminiscent of Kapurpurawan Rock Formation in Ilocos Norte. Hali thinks they look like a dessert background in Star Wars, which I can definitely see.

With the rest of the tour group, we climbed a cliff that offers a nice overlooking view. I asked Hali to stay in the cliff and take pictures of me while I went down to one of the pools below, and it was some of my favorite photos during my travels.

From Bel-at & Caranas rock formations, we rode the habal-habal to Magasang rock formation. We wade through shallow seawater to get to the actual rock formation. There is a bridge in the middle that helps tourists cross and also serves as rest stops for families with picnic items.

Similar to Bel-at, the floor in Magasang was slippery. Moss covers some of the surface. One of our companions slipped, so our tour guide instructed us to walk across dry ground only.

The cliff in Magasang offers natural stairs so it’s possible to climb up all the way to the top. The surface here looked like spider webs, with natural footholds for climbing. It was tiring but the ocean view from above was rewarding.

Again, there’s a full horizon of boulders where the sea waves crash. It was fascinating to watch and somewhat relaxing.

Overall, we enjoyed our tour in Biri Island. I didn’t have much expectations on what to see here and so the views caught me by surprise. Biri Island is indescribably beautiful. It’s a definite must-see when you’re in Samar Province.

    Bookmarking this! I’ve always wanted to go to Biri! Should have went there when I was assigned in Catarman a few years back. Hopefully i’ll get to visit soon. Thanks for sharing!

    I have never heard of Bani Island, Samar. It looks a little bit like Australia the rock formations along the water. Sydney has a similar area. I would love to go to the Philippines soon!

  • yogoandcream

    The Biri rock formations look breath taking. Really majestic! Your posts never fail to inspire me to go out and travel. How I wish I can quit my job and just travel to the places you’ve went to. Hahaha! Anyway, I’m happy to hear that the Samar locality continue to protect this gem. I am with you in hoping that they keep it regulated and protected. Also, I hope that people will support tourism in this place by hiring local guides. Thank you for sharing 🙂

    Biri reminds me a lot of Kapurpawan in Ilocos. They have similar rock formations. I’m not sure which one is more beautiful but I want to go to Biri and find out myself. Your photos alone look gorgeous.

  • Nicole Paler

    I loved the Bel-at rock formation more than the masagang rock formation, as the Bel-at looks like the perfect place to take photos for prenups, especially for the more adventurous couples out there. Looks so majestic and breathtaking. Okay, so maybe I want my own prenup to be done there soon enough when my husband and I renew our vows… Here’s hoping! Thanks by the way for sharing the gems of the Philippines, I’m including this in my bucket list 🙂

    I always have seen pictures of beautiful places in the Philippines, but this by far is my favourite post. I love the pictures that you use, and the detailed information about the Biri Rock formations. I think it is great that the rock formations are also protected as sadly, lots of beautiful places are easily destroyed when proper care of the location is not taken! I will be sharing this post on my travel group. Wonderful!
