Garden Eels
Also known as: Eel Garden, Garden Eel
A coral-topped wall west of Alona Beach dived mostly after dark, named for a garden eel colony that drops into the sand as you approach.

The dive
Anthias sit over the coral garden on the reef top, three to five metres down, in the redfin and amethyst and purple that give the first minute of this dive its colour. Ninety seconds later there is an edge. It bows outward and the drop off it is nothing like clean. That lip is where the guide slows down, because the head of the wall is where the nudibranchs are.
Below the lip, peacock mantis shrimp watch from burrows along the drop-off. The wall itself carries cracks and small recesses, and they hold the macro the site is worked for: warty and giant frogfish, ornate and robust ghost pipefish tucked into feather stars, boxer shrimp, sponge crabs, a spider crab when somebody is looking hard. Batfish school off the face. Snappers come down it in a cascade.
At twenty to twenty-five metres the wall meets sand, and this is where the name is. Spotted garden eels, Heteroconger hassi1, stand out of the slope in a field, and they go back into it as you cross toward them2. That retreat is normal behaviour and not a bad night. They drop tail-first, and they come back up slowly once whatever alarmed them has passed3.
Then back up the wall, because the best of this dive is above the thing it is named after. Six to eighteen metres is the band, and around twelve is where most of the time gets spent.
What makes it special
After dark, Panglao's headline diving is unavailable. Balicasag, Pamilacan and the north-coast walls all want an early boat and a crossing, and none of them run at night. What is left is the few hundred metres of wall within a three-minute banca ride of Alona Beach, and several operators on the Alona strip sell this site for exactly that.
The odd part is the name. A colony of shy, plankton-feeding eels occupies the bottom of the profile, on a site sold almost entirely after sunset. They are not why anyone books it in the evening. Divers come for the upper wall, which is a macro hunt: nudibranchs in numbers, mantis shrimp in their burrows, frogfish sitting flat against sponge, and the kind of searching that rewards carrying your own light.
Depth discipline is the other half of it. The interest band sits between six and eighteen metres, so a night dive here does not also have to be a deep one, and an Open Water diver gets the whole of what the site is good at without the profile becoming the harder part of the evening.
Know before you go
The night dive here is priced without a torch. Settle it at the shop, in daylight. Finding out at the boat is the expensive version, and the light you end up with wants to be one you would happily dive behind for an hour.
Sand first, wall on the way back. That is the order the dive gets described in, and at night the order matters more than usual, because the eels are the deepest thing here and they sit at the far end of the profile. The slope runs to twenty-five metres. How far down it you go should follow your certification and not the terrain, and that is a decision for the boat.
Cross the sand slowly or you will be looking at an empty field. The colony closes as divers come over it and reopens once you have been still for a while3, so distance and patience get you more of it than swimming closer ever will.
The site lies about a hundred metres off a busy beach, on the stretch between the Alona strip and Danao where the bangka fleet moors. Send a marker before you surface. The reef top is the place to come up, not the open water off the wall.
The nearest chamber to plan on is off Bohol entirely, across the strait on Cebu, so carry cover that pays for an evacuation.
Why Dive Garden Eels
What makes this dive site stand out.
- The Alona night dive
Several operators on the Alona strip sell it for night diving
- Nudibranchs on the wall top
Macro along the lip where the reef breaks away
- Shy garden eel colony
A field of eels at the foot of the wall that empties as divers cross toward it
- Three minutes by banca
West of Alona Beach, so no early start and no crossing
- Shallow interest band
The interest band runs from 6 to 18 m
Depth & Profile
Location
9.5452°N, 123.7710°E
Conditions & difficulty
A coast question before it is a month question. This is the south side, so the northeast amihan from about November to April is the calm window and Alona, Tawala and Danao are where the boats go. Through the southwest habagat from June to October the south side turns choppy and shops move around to the west and north coasts.
One Alona operator prices its night dive at PHP 1,950 excluding torch rental, and rents a torch at PHP 300 per dive. Quoted per operator.
Open Water is the stated level and the site is built for it, with the interest band at 6 to 18 m and no overhead, no drift and no penetration anywhere on it. The eel colony at 20 to 25 m sits below the Open Water depth limit, so an Open Water diver's version of this dive stops on the wall above the sand.
Summary
Easy on every measure that gets taken: a three-minute boat ride, mild current and a shallow band holding most of what divers come for. Two things sit behind the rating. The named animal is at the deepest point of the profile and at the far end of it, and most of the diving here happens in the dark.
Safety considerations
What can go wrong here, and what divers do about it. Conditions change - take the briefing from the operator on the day.
- Conditions: Most of the diving here happens after dark, and a torch is not part of what the night dive includes.Settle the light at the shop in daylight and carry a backup on any night dive.
- Depth: The eel colony is the deepest thing on the dive and it sits at the end of the route, which is where a night dive plan gets overrun.Fix the turn-around depth on the boat and let it follow your certification and not the terrain.
- Surface and boat traffic: The site lies about a hundred metres off a busy beach, between the Alona strip and Danao, where the bangka fleet moors.Send a marker before surfacing, day or night, and ascend over the reef top, never in open water off the wall.
- Marine life: Lionfish work this wall and scorpionfish sit on the reef along this coast, both of them hard to pick out in a torch beam.Stay off the wall, hover, never settle, and light a surface before you get close to it.

Frequently Asked Questions
Can you see the garden eels on a night dive at Garden Eels?▾
Plan the night dive around the wall, not the eels. What the site delivers after dark is macro along the top of the wall and the drop-off: nudibranchs first, then mantis shrimp in their burrows, frogfish, ghost pipefish in the feather stars. The eels are a daytime, plankton-feeding animal that lives in a burrow at 20 to 25 m and goes back into it when anything comes close, and nothing describes them as a night attraction here. If the colony is what you came for, do this site in daylight as well.
How deep is Garden Eels, and does it matter for an Open Water diver?▾
Operators disagree: 5 to 23 m, 4 to 30 m, 5 to 25 m and 4 to 40 m are all published for the site. The dive as described turns around at about 25 m depending on the diver's level, and the interest band is 6 to 18 m. The gap matters because the eel colony sits at 20 to 25 m, below an Open Water diver's depth limit, so an Open Water version of this dive stays on the wall above the sand and loses nothing of the macro.
Is Eel Garden the same place as Garden Eels?▾
Yes. Both names are in live use on Panglao for the same piece of wall west of Alona Beach, and which one you see depends on which shop wrote the list. The name travels, though: there is an Eel Garden in Dahab and another in the Maldives, and a Garden Eel Cove in Hawaii. If you are booking or searching, add Panglao or Alona Beach to the name.
How many species of garden eel are at this site?▾
The spotted garden eel, Heteroconger hassi, is the one to expect, and it is what the field on the sand is made of. A second and much showier species, the splendid garden eel Gorgasia preclara, is also described on the same slope by one operator. Treat that one as a maybe and never a target: its usual depth starts around 30 m, which is below where this dive ends, so if it is here it is either at the shallow edge of its range or further down the sand than anybody dives.
