About This Dive Site
Basura (Anilao): A Muck Diver's Treasure Trove
Welcome to Basura, a truly classic Anilao dive site renowned as a premier destination for muck diving enthusiasts and macro photographers. Named for the discarded tires, bottles, and shoes that formed a unique habitat for marine life when it was discovered in the early 2000s, this site beautifully illustrates how life adapts and thrives even among human debris. Divers will find a gentle, sloping sand-and-rubble bottom, which transforms into lush beds of seagrass during the summer months, providing exquisite photographic backdrops and hiding spots for an incredible array of critters.
Diving Conditions
- Difficulty: Basura is an excellent dive site for beginner divers.
- Certification: An Open Water certification is required to explore this fascinating underwater world.
- Depth: Divers can explore a comfortable range, with a maximum depth of 18 meters, typically sloping from 3 meters.
- Current: We are pleased to report that current at Basura is usually none, making for relaxed and leisurely dives.
- Temperature: Water temperature in Anilao generally ranges from 25°C to 30°C, though it can be cooler in January and February, averaging around 25°C, and warmer in summer months, reaching up to 30°C.
- Visibility: Visibility is consistently good, often exceeding 10 meters. However, during the rainy season (July to September), divers should be aware that visibility can be reduced.
Marine Life Encounters
Basura is a veritable hunting ground for rare and captivating macro subjects. Divers will be delighted by the sheer diversity of life thriving in this unique environment. Keep your eyes peeled for:
- Frogfish: Both the vibrant Painted Frogfish (Antennarius pictus) and the elusive Hairy Frogfish (Antennarius striatus) are frequently spotted here.
- Octopus: The intelligent and highly camouflaged Mimic Octopus (Thaumoctopus mimicus) is a highlight, known for its incredible ability to impersonate other marine creatures.
- Pipefish: Look for the delicate and ornate Ornate Ghost Pipefish (Solenostomus paradoxus), masters of disguise.
- Shrimp: The striking Harlequin Shrimp (Hymenocera picta), with its distinctive patterns, is a prized find.
- Worms: The formidable Bobbit Worm (Eunice aphroditois), an ambush predator, can sometimes be observed emerging from the sand.
- Seahorses: The charming Thorny Seahorse (Hippocampus histrix) adds to the site's allure.
- Nudibranchs: Basura is particularly famous for its incredible variety of assorted Nudibranch (Nudibranchia spp.), making it a top spot for nudibranch enthusiasts and photographers.
Hazards and Recommendations
While Basura offers an easy and leisurely dive experience, especially for macro and night diving, divers should be mindful of a few potential hazards:
- Boat Traffic: As with many popular coastal dive sites, awareness of boat traffic is important, particularly during ascents and descents.
- Dangerous Marine Life: While fascinating, some marine life, such as certain species of sea urchins, can pose a hazard. Stinging sea urchins, including the dangerous Fire Urchin (Asthenosoma varium), are known to proliferate, especially during the rainy season, and can inflict painful stings. We recommend maintaining a safe distance and exercising caution.
- Silting: The sandy and silty bottom means that silting can occur if divers are not careful with buoyancy and finning techniques. Good buoyancy control is key to preserving visibility for yourself and others.
Basura remains an essential dive site for anyone visiting Anilao, offering an unparalleled opportunity to witness the intricate beauty of the macro world. We highly recommend it for photographers and those looking to discover the smaller, often overlooked, wonders of the ocean.
