Marine Sanctuary in Dauin, is about 15-30 minutes travel from Dumaguete City. For those taking the public transport, you can find jeepneys to Dauin at the bell tower in Dumaguete City or near the Robinson's Mall. Fare is PHP 13.00. Inform the driver you are getting off at the corner leading to the Marine Sanctuary. It’s a couple of blocks away or a good 4-5 minutes brisk walk. The entrance fee for the sanctuary is PHP 150 with a table included. Without table it will be less.

The beach with its brown sand may not look like much but wait until you get in to the water. The Marine Sanctuary starts a few meters from the shore and remains fairly shallow for about 20-50 meters before it slopes down into the deep. It's best to start snorkeling in the mid-morning until lunch, as the water gets shallower towards the afternoon. It said you can expect to see parrot fish, clown fish, anemone fish, neon damsels, hump-head banner fish, some baby black tip sharks, boulder coral, giant lobe and whorl bowl corals at the center. I myself saw most of the fish mentioned and also spotted a muraena. I didn't see any black tip sharks though. 

Casaroro Falls is located in Valencia roughly 10 km from Dumaguete. It’s considered to be the most photographed waterfall in the entire Negros province. To get there, take a jeepney from Dumaguete to Valencia Plaza, it takes 20-30 minutes depending on the traffic. The fare is 12 PHP per person. At Valencia Plaza take a Habal Habal up to Casaroro falls. Ask the driver to wait for you. The fare should be around 200 PHP per person and back and forth. Always try to negotiate. Travel time is around 20 minutes.

From the drop off point you need to hike. There will be steep stairs going down at first, it’s said to be 350 steps. I haven’t counted them but it might be true. Additional hike is required after the stairs. Be prepared for wet feet and to stumble around among slippery rocks. Depending on your fitness level the hiking time to the falls would be from 15 minutes and plus. The waterfall is mighty, beautiful and really worth the effort.
