# Osa Peninsula Ranks 4th on NYT's 2026 List as Corcovado Limits Tested > In January 2026 The New York Times ranked Costa Rica's Osa Peninsula 4th on its annual 52 Places to Go list, praising it as a quieter, wilder alternative to busier regions. By mid-year the attention had collided with a hard limit: a failing wastewater plant at Corcovado's Sirena station forced a temporary visitor cap, protests and, in September, a return to 366 daily visitors. Source: https://pura-verde.com/news/osa-peninsula-2026-new-york-times-travel-list/ Last checked: 2026-11-03 The New York Times opened 2026 by naming Costa Rica's Osa Peninsula the 4th pick on its annual 52 Places to Go list, behind only Revolutionary America in the U.S., Warsaw and Bangkok. It was the only Central American place on the list. What followed over the next nine months showed why a ranking is the start of a conversation about Osa, not the end of one. ## What the Times said about Osa [La Nación reported](https://www.nacion.com/economia/un-destino-de-costa-rica-entro-en-la-lista-de-los/CQUZHQUQMFAE5HMSAEA3T542TE/story/) the ranking on Jan. 9, a couple of days after [El Observador](https://observador.cr/the-new-york-times-recomienda-visitar-la-peninsula-de-osa-en-el-2026/) first flagged it. The entry, written by travel journalist Liza Weisstuch, pitched Osa as a calmer alternative to the Nicoya Peninsula, where visitors have long clustered. It pointed to trails in Corcovado National Park that are less crowded than other famous parks, sloths and monkeys in the wild, and the waters around Caño Island, where divers and snorkelers find reefs, sea turtles, dolphins, sharks and rays. It also mentioned new restaurants and wellness-focused small hotels around Uvita and Ojochal, and better flight connections to Costa Rica. It's worth being clear about what the list is: an editors' selection of places to visit, not a sustainability certification or a judgment on how well tourism is managed there. No Costa Rican agency or local group was quoted in the coverage. ## Why Osa is special, and fragile Corcovado is often called one of the most biologically intense places on Earth. El Observador's background notes put it at roughly 2.5% of the planet's biodiversity on a tiny fraction of its land, with around 500 bird species, including scarlet macaws, and about 140 mammal species, from tapirs to jaguars. The park covers about 424 square kilometers, and Caño Island is a marine biological reserve. That richness depends on forests that were cut back for cattle ranching for decades, and on long-running work by rangers, researchers, guides and groups such as [Osa Conservation](https://osaconservation.org/), which focuses on protecting southern Costa Rica's biodiversity, research and local livelihoods. Our story on [the jaguar Encanto reappearing on an Osa camera trap](/news/jaguar-encanto-osa-camera-trap/) shows what's at stake. ## The summer test at Sirena Corcovado's Sirena Biological Station is the heart of the park for most visitors, and in 2026 it became the focus of a hard argument about how many people the place can take. On June 24, ACOSA's acting regional director, Juan José Jiménez Espinoza, issued a temporary, precautionary cap of 150 people a day at Sirena, according to [Semanario Universidad](https://semanariouniversidad.com/pais/ministra-reubica-a-director-de-acosa-que-redujo-aforo-en-corcovado-por-colapso-de-planta-de-aguas-residuales-y-dano-ambiental/). The reason was the station's wastewater treatment plant. It was designed for about 100 people, had been overloaded for years, and a Ministry of Health report from October 2025 had confirmed a discharge into the Camaronal stream. The resolution also cited a 2025 Constitutional Court order to regulate visitor numbers. The cut hit a peninsula where many families live from guiding, boats and lodging. On June 30, dozens of tour operators and residents blocked the Costanera Sur highway near Uvita in protest, fearing lost jobs, [CRHoy reported](https://crhoy.com/nacionales/vecinos-y-tour-operadores-protestan-por-reduccion-de-aforo-en-corcovado). In early July, Environment Minister Mónica Navarro del Valle, who took over the ministry when President Laura Fernández's government began in May, moved Jiménez to another SINAC post, citing a human-resources recommendation. ## What happened next After repairs to the treatment plant, carried out with communities, organizations and volunteers, SINAC said it had met the health orders and permits. On Sept. 17 it restored Sirena's limit to 366 daily visitors, [Delfino.cr reported](https://delfino.cr/2026/09/parque-nacional-corcovado-restablece-aforo-de-366-personas-diarias-en-estacion-biologica-sirena), adding that the decision drew on its visitor-flow management tool. As usual, Sirena, El Tigre and Los Patos closed for October maintenance and the rainy season, while San Pedrillo and La Leona stayed open. We covered the background in [Corcovado's sewage 'red alert'](/news/corcovado-sewage-red-alert/) and [Sirena's capacity being restored](/news/sirena-station-capacity-restored/). As of Oct. 31, there's no public data showing whether the Times listing itself changed visitor numbers on the peninsula. ## What it means if you're going The year's lesson is simple: Osa's popularity and its limits are now part of the same story. If you go, book park entry through official channels and licensed local guides, expect visitor caps and seasonal closures, and consider spending more nights in one community rather than racing to Sirena and back in a day. Our guides to [responsible ecotourism tours](/responsible-ecotourism-tours-costa-rica/) and [biological research stations](/biological-research-stations-costa-rica/) can help you plan. ## Frequently asked questions ### What number was the Osa Peninsula on the New York Times 2026 list?
