A routine Belize Defence Force patrol around Sarstoon Island turned tense on November 7, when two Guatemalan naval vessels allegedly crossed into Belizean waters, bumped the BDF boat and tried to block its path near the country's southernmost border. No one was hurt — the Belizean crew completed its patrol and returned safely to the Sarstoon Forward Operating Base — but the incident has pushed a long-running territorial dispute back into the headlines.
Belize's government condemned what it called an act of aggression, dispatched extra BDF and Belize Coast Guard personnel and vessels to the base in the Toledo District, and said it would file a formal protest with Guatemala plus a report to the Organization of American States. Guatemala's military tells a different story, insisting its personnel were enforcing boundaries in Guatemalan waters and that the Belizean vessel simply turned back. Rear Admiral Gregory Soberanis, head of the Coast Guard, visited the deployed troops on November 8 to urge vigilance.
The root of the friction is old. Belize argues the 1859 treaty between Guatemala and Britain set the border along the mid-channel of the Sarstoon River, which puts Sarstoon Island on the Belizean side. Guatemala disputes that and, more broadly, claims more than half of Belize's territory along with its maritime zones and islands. The case is now before the International Court of Justice, with oral hearings reportedly set to begin in February 2027. Belize says it remains committed to a peaceful resolution and that both nations are obliged to avoid inflaming the dispute.
Why should holidaymakers care? The Sarstoon sits at the far southern edge of Toledo, one of Belize's wildest and least-visited districts — a draw for travellers seeking rainforest lodges, Mayan villages and rivers far from the cruise-ship crowds of Ambergris Caye. The river itself has seen repeated friction over the years, and while this incident involved military personnel rather than tourists, it's worth knowing the area is an active, sensitive border zone. If you're heading to Punta Gorda or into the Toledo backcountry, keep an eye on local advisories, avoid crossing toward the river's southern bank, and go with licensed local guides who know where the practical limits are. For now, the rest of Belize — reef, cayes, jungle — operates as normal, and travellers are not being warned away from the country.
