Serangan Island Guide: Home of Turtle Island Bali & the 498-Ha SEZ

Serangan Island is a small island off the coast of South Denpasar District, Bali, reached by a short causeway from the Ngurah Rai Bypass, and it is home to two very different versions of “Turtle Island”: the traditional fishing village with its sea turtle conservation heritage, and the 498-hectare Kura Kura Bali Special Economic Zone (SEZ) developed by PT Bali Turtle Island Development (BTID). This guide explains exactly where Serangan sits, which parts of the island the public can visit, how the SEZ works, the best road access from Sanur, Kuta and Nusa Dua, and how to time a visit — whether you are a traveler who wants to meet turtles or an executive who wants to see the development zone firsthand.

Where Serangan Island Sits in South Denpasar

Serangan lies just off the southeastern shoreline of Denpasar, administratively part of South Denpasar District, Denpasar City. On the map, it occupies the sheltered water between Sanur to the north and the Benoa Bay area to the south — a position that puts it within a short drive of every major hub in South Bali. Sanur’s beachfront, the Ngurah Rai Bypass corridor, Ngurah Rai International Airport, Kuta and Nusa Dua all sit within the island’s immediate orbit.

That location is why Serangan carries such strategic weight: for travelers, the closest drive-to island escape from Bali’s resort belt; for investors, a rare large, contiguous, master-planned parcel minutes from an international airport — the geographic logic behind its designation as a Special Economic Zone.

Two Faces of One Island: Turtle Heritage Village and the 498-Hectare SEZ

Understanding Serangan means understanding that “Turtle Island” refers to two distinct things that happen to share one piece of land.

The first face is the original Serangan: a Balinese fishing village whose name has been tied to sea turtles for generations. In Indonesian, “kura-kura” means turtle, and the island’s long association with turtle nesting and, later, turtle conservation is the reason the “Turtle Island” name exists at all. Today that heritage lives on through the village community, local conservation activity and the boat-based turtle tours that most travelers actually book. If your goal is the visitor experience — seeing turtles, snorkeling, glass-bottom boats — start with our complete Kura Kura Bali Turtle Island guide, which covers the tours in full.

The second face is Kura Kura Bali: a 498-hectare Special Economic Zone formally established by Government Regulation No. 23 of 2023, signed on 5 April 2023, and developed and managed by PT Bali Turtle Island Development (BTID). This is a long-horizon, master-planned development focused on quality tourism, creative industries, hospitality, residential, commercial and education functions — with a stated national ambition to host an international financial center. The SEZ is not a tourist attraction in the conventional sense; it is a development zone with its own gates, phasing and access arrangements.

These two identities create two very different intents, and this website deliberately routes them to different pages: travelers to the tour-focused guides, executives and investors to SEZ-focused pages such as this one — so nobody books the wrong thing.

Kura Kura Bali SEZ: Verified Facts at a Glance

For readers who want the hard numbers on the zone itself, here is what the public record supports:

• Legal basis: Government Regulation (PP) No. 23 of 2023 on the Kura Kura Bali SEZ, signed 5 April 2023.
• Area: 498 hectares on Serangan Island, South Denpasar District. The initial environmental permit, issued in 2017, covered 491 hectares and was later expanded to 498.
• Developer and manager: PT Bali Turtle Island Development (BTID) — the corporate name itself translates the island’s identity as “Bali Turtle Island.”
• Focus sectors: quality tourism and creative industries, with hospitality, residential, commercial, education and marine tourism functions in the master plan, plus a planned international financial center role.
• Momentum: the zone reportedly reached 75% of its realized investment target in 2024 and ranked among the top eight SEZs nationally; by Q1 2026 it had recorded roughly IDR 1.62 trillion in realized investment and 2,146 jobs created.
• Financial center ambition: national coverage cites an investment target of around IDR 104.4 trillion (approximately US$6 billion) for the international financial center concept, though as of mid-2026 a full financial-sector regulatory framework for the zone was still in progress.

SEZ regulations, incentives and access policies change; before making any investment, visa, licensing or legal decision connected to Kura Kura Bali or Indonesian SEZs, verify current rules with licensed Indonesian legal counsel, a registered tax advisor and the relevant government authorities.

Road Access from Sanur, Kuta and Nusa Dua

One of Serangan’s most underrated advantages is that it is a drive-to island. A causeway links Serangan to the mainland road network at the Ngurah Rai Bypass, the main artery running along South Bali’s eastern coast, so no boat transfer is needed to reach the island itself.

Indicative drive times outside peak traffic:

• From Sanur: the shortest approach — typically around 15–25 minutes via the Bypass heading south to the Serangan turn-off.
• From Kuta and the airport corridor: roughly 25–40 minutes depending on traffic through the Dewa Ruci interchange and along the Bypass.
• From Nusa Dua: roughly 30–45 minutes north along the Bypass, with the toll road option shortening parts of the run at busy hours.

All timings are indicative; late afternoons around Dewa Ruci can add significant time. For business itineraries where punctuality matters, a private driver who knows the Bypass timing patterns is worth far more than the marginal cost. The premium Bali trip programs run by Bali Premium Trip, the concierge arm of the Juara Holding Group ecosystem, handle exactly this kind of door-to-door executive routing across South Bali.

What the Public Can Visit vs BTID Development Areas

Because one island hosts both a living village and an active development zone, it pays to know what is open to whom.

Generally open to the public: the Serangan village area, local warungs and the working fishing harbor; the island’s beaches and surf spots popular with domestic visitors; and the turtle conservation activity that made the island famous, which most travelers experience either on-island or via the classic glass-bottom boat tours departing from Tanjung Benoa. Visitors are welcome, and the usual temple etiquette applies around religious sites.

Development and managed areas: substantial parts of the 498-hectare SEZ are master-planned land under BTID’s management, with construction phases, gated sections and event venues that open selectively. Access arrangements for these areas change as the project develops — some zones host public events, some are open by arrangement, and some are closed work sites. Do not assume free access to development land, and treat on-site signage and security direction as authoritative.

For maritime arrivals: the island’s marine-facing masterplan includes marina and boating functions, and arriving by sea is increasingly part of the Serangan story. If you are exploring yacht access, berthing or a charter arrival, see our dedicated Kura Kura Bali marina and yacht charter page for how the water-side approach works.

The Best Calendar for an Executive Visit

If you are visiting Serangan to evaluate the zone rather than to swim with turtles, timing matters in three ways.

Season: Bali’s dry season, roughly April through October, offers the most reliable conditions for walking land parcels, viewing sightlines and moving between outdoor locations. The wetter months from November to March still allow productive visits, but afternoon downpours can compress your usable field time — schedule site walks for mornings.

Traffic windows: mid-morning arrivals (after 9:30) and early-afternoon departures avoid the worst Bypass congestion. Friday afternoons and days around major Balinese ceremonies deserve extra buffer.

Business calendar: Indonesian public holidays, Nyepi (the island-wide day of silence, when even the airport closes), and the Galungan–Kuningan ceremonial periods affect the availability of local counterparties. Confirm meeting availability before locking flights.

For a structured visit — ground transport, scheduling around the ceremonial calendar, meeting coordination and English-speaking support on the ground — our Kura Kura Bali executive site visit service packages the full day so you can focus on the evaluation itself.

Indicative Costs for Visiting Serangan Island

Costs vary with season, group size and how you arrange the visit. The figures below are indicative only and should be confirmed at booking.

Because the SEZ is an evolving project, anything touching the development side — venue access, event participation, berthing — is quoted case by case rather than off a rate card.

Frequently Asked Questions

Is Serangan Island the same as Turtle Island Bali?

Yes — Serangan is the island that both meanings of “Turtle Island” refer to. The traveler meaning covers the turtle conservation heritage and boat tours; the business meaning covers the 498-hectare Kura Kura Bali SEZ. “Kura-kura” is simply Indonesian for turtle, which is why the SEZ brand, the developer’s name (Bali Turtle Island Development) and the tourist nickname all converge on the same island.

Can tourists visit the Kura Kura Bali SEZ area?

Parts of the island, including the village, beaches and conservation areas, are generally open to visitors, while sections of the SEZ are managed development land with changing access arrangements. Some zones open for public events; active construction areas do not. Check current access before planning anything on the development side of the island.

How do I get to Serangan Island from Kuta or Sanur?

By road via the causeway off the Ngurah Rai Bypass — no boat is required. Indicatively, allow 15–25 minutes from Sanur and 25–40 minutes from Kuta outside peak traffic. Most turtle-focused boat tours, however, depart from Tanjung Benoa rather than from Serangan itself.

What is the best time of year to visit Serangan?

The dry season from roughly April to October offers the most dependable conditions for both leisure visits and site inspections. Executive visitors should also plan around Nyepi and the Galungan–Kuningan periods, when local availability changes significantly.

Who develops the Kura Kura Bali SEZ?

PT Bali Turtle Island Development (BTID) is the developer and manager of the zone, which was formally established as a Special Economic Zone by Government Regulation No. 23 of 2023. The zone’s focus spans tourism, creative industries, hospitality, residential, commercial and education functions, with a planned international financial center role.
