Key Dive Site Facts
Dive Site Overview
Gili Tepekong presents an extreme underwater landscape off eastern Bali, appealing to experienced divers. This small volcanic island, situated near Candi Dasa in Amuk Bay, plunges abruptly into the sea.
Divers encounter dramatic walls, surge-filled swim-throughs, and a notable canyon often called 'The Canyon' or 'The Blue Hole'. Its foundational structure consists mainly of lava rock, forming complex ledges and intricate passages that define the dive profile. Depths range from about 10 meters (33 ft) in shallower reef areas to over 40 meters (130 ft) along its sheer east wall, a truly vertical drop-off that tests diver limits.
The island's exposed position makes it highly susceptible to the powerful North Current, which means conditions can fluctuate significantly throughout the day and with seasonal changes. These dynamic currents often dictate dive profiles, demanding constant awareness.
Diving here consistently demands advanced certification and a high level of comfort with challenging currents, often necessitating techniques like negative entries and drift diving. It's not a site for the uninitiated.
Precise buoyancy control is critical for navigating both its deeper sections and the vibrant, current-swept reef environments, ensuring safety and allowing appreciation of the site's unique features.
Best Time to Dive
Seasonal considerations significantly impact the diving experience at Gili Tepekong, especially concerning visibility and marine life sightings. While diving is possible year-round, August through October generally offers the best visibility, often reaching 15-30 meters (50-100 ft). This period also coincides with the prime season for pelagic encounters like Mola Mola, which tend to appear from July to October, along with various sharks and barracudas. Air temperatures during these months remain pleasant, averaging 24.7-26.8°C (76-80°F), with lower rainfall compared to the wet season. During months like January and February, air temperatures hover around 26.7-26.8°C (80°F), but wave heights and rainfall may be slightly elevated.
