Gili Gede is the largest island in the Sekotong Bay archipelago — roughly 4km long with multiple dive sites accessible by short boats from any of its eco-resorts. The signature site is Gili Gede Wall on the east side (8–28m, schooling jacks, occasional turtle, healthy soft coral). Two strategies for diving here: stay at one of the eco-resorts (Gili Asahan Eco Resort, Madak Belo) with included dive packages, or day-trip from Sekotong village. Fun dive 475–575k IDR; eco-resort dive packages 1.8–3M IDR per night including 2 dives.
# Diving Gili Gede: The Largest Secret Gili
Gili Gede is the biggest island in the Sekotong Bay archipelago — roughly 4 kilometres long, hilly, and dotted with three or four small eco-resorts and a handful of fishing villages. Unlike the smaller, day-trip-oriented Secret Gilis (Nanggu, Sudak, Kedis), Gede has the scale to support actual overnight diving operations and a multi-site dive program from a single base.
If you're committing to multiple days of Sekotong diving, Gili Gede is the more sophisticated base than Sekotong village.
Three reasons:
1. Multiple sites within range: From a Gili Gede eco-resort you can reach 6+ dive sites in 10–25 minutes by boat, including the dramatic Gili Gede Wall, Gili Layar Drift, Gili Rengit Channel, and the smaller Gili Asahan reefs.
2. Eco-resort dive packages: Gili Gede has 3–4 eco-resorts (Gili Asahan Eco Resort, Madak Belo, Eco Resort Gili Gede) that sell combined accommodation + diving packages with breakfast, lunch, and 2 dives per day. This is the most efficient way to dive Sekotong seriously.
3. The Wall: Gili Gede Wall is the most dramatic dive site in the Secret Gilis archipelago. It's not Meno Wall in scale, but the topography, current, and marine life make it a genuine intermediate-and-up dive worth the trip.
The trade-off vs the Gili Trio is no iconic 'wow' photo site (no NEST statues, no Meno Wall) and smaller-scale operators.
Two strategies:
Strategy 1: Stay at an eco-resort
The eco-resorts (Gili Asahan Eco Resort, Madak Belo) sell dive-and-stay packages: accommodation + meals + 2 boat dives per day. These run 1.8–3M IDR per person per night depending on accommodation type. The dive operations are run by the resort itself or by a partnered shop (often Sekotong Dive Centre).
This is the most efficient way to dive Sekotong seriously. You wake up, walk 50m to the boat, dive, return for lunch, dive again, and never deal with the boat ride from Sekotong village.
Strategy 2: Day-trip from Sekotong village
Day-trip divers book through Dive Sekotong (PADI, Sekotong village). The boat from Sekotong jetty to Gili Gede dive sites is 25–35 minutes. Cost is 900k–1.1M IDR for a 2-tank trip including transfers and lunch.
This works fine for 1–2 day dive trips but gets tedious if you're doing multiple days.
Gili Gede Wall (8–28m): The flagship. Modest coral wall on the east side of the island, drops from 8m to 28m+. Schooling jacks, occasional turtle, soft coral on the deeper sections, white-tip reef sharks resting on the sand at depth. Intermediate due to depth and tidal current. Best dive in the Sekotong area.
Gili Layar Drift (12–25m): Drift dive on the north side of Gili Layar (10 min boat from Gili Gede). Strong current on tidal change — guide-only. Schooling barracuda, occasional grey reef shark, healthy soft coral. Intermediate.
Gili Rengit Channel (10–22m): Channel dive between Gili Rengit and Gili Gede. Current-dependent. Pelagic fish on incoming tide, schooling fusiliers. Intermediate.
Gili Asahan Slope (8–20m): Gentle reef slope on the east side of Gili Asahan (5 min boat). Good macro — nudibranchs, ghost pipefish in season. Beginner.
Gili Genting (10–25m): Less-dived site on the south side of the bay. Coral garden with occasional turtle and reef shark. Beginner to intermediate.
Gili Poh (8–18m): Rarely visited site between Gili Gede and Gili Layar. Hard coral cover and schooling reef fish. Beginner.
Gili Gede North Slope (8–22m): The northern reef of Gili Gede itself. Less famous than the Wall but with consistent turtle sightings. Beginner to intermediate.
Gili Gede South Reef (5–15m): Shallow reef on the south side of the island. Easy site, good for warm-up dives. Beginner.
Day-trip from Sekotong village or Gili Asahan:
Eco-resort dive packages:
Courses (most run from Sekotong Dive Centre or Dive Sekotong):
For a 4-night dive trip with 8 dives, the eco-resort package usually works out 10–20% cheaper than separately booking accommodation in Sekotong village + day-trip diving.
Topography: a modest reef wall on the east side of Gili Gede, running roughly north-south for about 200m. The wall starts shallow at 8m on the south end, drops to 18–22m in the middle section, and reaches 28m+ on the north end. Soft coral cover is concentrated in the 15–22m range.
Plan: descend on the line near the south end, follow the wall north, watch for the schooling jacks that often hold position in the channel beyond. Bottom time 40–45 minutes. Safety stop along the upper wall in 5m surrounded by reef fish.
Marine life:
Visibility: 18–25m in dry season, 12–18m in wet season.
Current: variable. Slack tide is the safe window. On tidal change a moderate current runs along the wall, which can become strong (1.5+ knots) on big spring tides. Your guide will check the tide table and time the descent accordingly.
June–September: Peak. Visibility 20–25m, calm seas, water 27–28°C. Book the eco-resorts in advance.
April–May & October: Shoulder. Visibility 15–22m, occasional rain, fewer crowds, slightly cheaper packages.
November–March: Wet season. Visibility 8–15m, occasional storms cancel boats. Diving still possible most days.
September is the single best month — peak clarity, post-August quiet, water still warm, eco-resorts past their peak booking.
A 4-night eco-resort dive package itinerary:
Day 1: Arrive Mataram or LOP, transfer to Tembowong jetty, boat to Gili Asahan Eco Resort, evening dive at Gili Asahan Slope.
Day 2: Morning Gili Gede Wall + afternoon Gili Layar Drift.
Day 3: Morning Gili Rengit Channel + afternoon Gili Gede North Slope.
Day 4: Morning Gili Gede Wall (second time for photos) + afternoon Gili Genting.
Day 5: Boat back to Tembowong, transfer to Mataram or onward.
Total: 8 dives over 4 days. Cost: 7–12M IDR per person all-in for accommodation + diving + meals.
Be honest:
If your priority is iconic dive shots and dining variety, dive Meno or Gili T. If your priority is genuine quiet, intact reef, and a sustainable dive base, Gili Gede wins.
Gili Gede is reached from Tembowong jetty in southern Sekotong (90-min drive from Mataram, 2 hours from Kuta). The boat to any Gili Gede eco-resort is 15–20 minutes. Most resorts arrange the full transfer from your accommodation or from the airport (LOP — 2 hours). Day-trip divers from Sekotong village or from Gili Asahan can boat to Gili Gede in 10–15 minutes for individual dive trips.
Gili Gede vs Gili Nanggu: Gede is much larger with more dive sites and offers eco-resort packages; Nanggu is smaller with one main reef and is fully day-trip oriented. Gili Gede vs the famous Gili Trio: Gede is dramatically quieter, with intact coral and almost no other dive boats; the Trio has more iconic individual sites and better course infrastructure. Gili Gede vs Gili Asahan: both are eco-resort destinations, but Gede is larger with more site variety while Asahan is smaller and quieter.
