We thought we'd be more free if we did the classic boat tour on kayak and rented one double kayak for 450. unfortunately the only sea kayak we saw in town was for 1.500 and this one we had took more effort, especially against the wind and waves. But it was a great day, very good experience. Do it if you have some energy.
From Coron Town we went straight across to a little fisherman village. We passed by some nice mangrove channels before the village and also right after found a nice lagoon with mangroves (some nice bird songs). Then we rowed on the Eastern side of this little island (taking it on our right side) and as we reached the southern end we saw a tiny island with the CYC beach on it. Nice place to rest and snorkel a little and cuddle the two poor white cats which were left on this little island. Then we went straight across to Coron Island and to Baluan Beach which is one of those calendar beaches. We paid 100 each to step on it and lazed around a little. Then we went across the Western edge of Coron Island towards the North (taking it on our right). We went into all the little lagoons we came across and we did come across many. It would be impossible t see some of the nicer ones by boat because the entrances were so shallow at times we hit the bottom of our kayak. We snorkeled occasionally and visited Barracuda Lake and Kayangan Lake. by that time it was 1 hour to the sunset and we felt very tired so we asked a tour boat which was also returning to Corn Town and they took us on board for free.
When we came back the people we rent the kayak from were really worried they said they were almost calling the coast guard because nobody ever came so late! This is a great surprise because if we were in just a better physical condition we were thinking to go to Siete Pecados and end in the hot springs, coming back few hours after sunset. So if you do this, let the people know. It takes time and energy but it is really really worth it. Take much water (no water or shops in any of these places, so we filled up from the rain water dripping from the rocks of Coron Island; very tasty!) And even though it was a cloudy day and we had T-shirts on, we got sunburnt on our faces and legs.
Later when we stayed in Concepcion we rented the local kayak (Php 300) which is a very small paddle banca and tried the local alternative. It is more balanced and moves very smoothly like a sea kayak should but the solid wood paddle is heavy and because of the outrigger bamboos on both sides, it’s not very maneuverable. But it was another great ride to a lonely white sand beach floating over corals by mangroves.
You can also do shorter trips or go towards Sangat Island from Coron Town through mangroves but just don't miss kayaking when you are in Coron!
Not a very popular activity to do in Coron, but I really enjoyed it since I watch a lot of Discovery and NatGeo. :)
The mangrove forest is thick and lush on both sides. If it's a high tide, you can enter from one side and exit at the other end. However, we were there during a low tide and there's not enough depth for the kayaks to navigate through. So we had to turn back around. This activity can take from 30-45 minutes, and a lot of muscle power.
I noticed that Tribal Adventure tours had several kayaks and organise kayak tours where you can enjoy camping on the islands, snorkeling, mountain biking on the locals islands. The fellow running the office was quite friendly, so for more information please look at the link below.
