# Poás Volcano National Park Reopened After a Week-Long Bridge Closure > Poás Volcano National Park reopened on Jan. 29, 2026, after a bridge over the Quebrada Tigre in Poasito, on the park's main access road, was found at risk of collapse and closed for just over a week. The bridge reopened with a 9-tonne weight limit and warnings of short closures. Conditions at Poás change often, so the reopening date isn't a guide to today's hours or access. Source: https://pura-verde.com/news/poas-national-park-reopens-bridge/ Last checked: 2026-10-31 For a little over a week in January 2026, one of Costa Rica's most visited volcanoes was cut off, not by an eruption but by a tired bridge. Poás Volcano National Park closed on Jan. 21 when engineers found serious damage on the main road up, and it reopened on Jan. 29 with a weight limit on the crossing. The episode is a reminder of how many things have to go right for a day trip to Poás. ## A bridge at risk of collapse The trouble was a small bridge over the Quebrada Tigre, a stream in Poasito de Poás, on National Route 120, the park's main access road. A field study by the Ministry of Public Works and Transport (MOPT) found damage that put vehicle traffic at risk, and traffic was stopped at 4 p.m. on Jan. 21, [La República reported](https://www.larepublica.net/noticia/riesgo-de-colapso-obliga-a-cierre-del-parque-nacional-volcan-poas-por-cinco-dias). The park was first expected to reopen on Jan. 25. Officials pointed drivers to the old Poás road, a steep, narrow municipal route fit only for four-wheel-drive vehicles. MOPT also moved a single-lane modular Bailey bridge to the site, and the National Roads Council (CONAVI) said that crossing would be restored within four weeks at most. ## The closure that kept getting longer On Jan. 26, after a new technical review, the closure was extended with no reopening date. SINAC said the park would reopen only once MOPT confirmed the bridge was safe, [El Observador reported](https://observador.cr/parque-nacional-volcan-poas-seguira-cerrado-por-tiempo-indefinido-hasta-que-mopt-repare-puente/). SINAC's Meryll Arias also reversed the earlier advice and told people not to use any alternate route to reach the park, since the detour was considered high-risk and emergency response there is limited. Temporary repairs had begun on Jan. 21, and crews kept working through the week. ## Reopening on Jan. 29, with conditions On Thursday, Jan. 29, MOPT cleared traffic over the repaired bridge and the park returned to normal operation, as [La Nación reported](https://www.nacion.com/el-pais/parque-nacional-volcan-poas-reabre-tras/P5KNUJG2HFDBRCINUD7MSALD44/story/) that morning. The conditions were strict: - **A 9-tonne weight limit** on the bridge. MOPT warned that heavier vehicles could damage it further or force a full closure. - **Possible short closures** in the following days while heavy machinery kept working. - **Rescheduling for affected visitors.** People whose tickets fell during the closure could ask SINAC's Poás office to move their visit. SINAC thanked visitors for their patience and said the safety of visitors and staff came first. We didn't find public reporting on whether the planned Bailey bridge was later installed or on a permanent replacement. ## Why a week matters to Poasito The road up through Poasito is known for its strawberry stands, restaurants and small lodges, many of which see much of their trade from park visitors. Officials noted that tourism around Poás supports the local economy and many small and medium-size businesses. A shutdown during the January high season hits those businesses directly, and this one came only six months after a much longer closure. ## Poás has had a turbulent two years In the first half of 2025, strong gas and ash emissions closed the park for months. It reopened on July 30, 2025, after the volcano's activity dropped, with online-only tickets and new emergency signs at the crater, [Teletica reported](https://www.teletica.com/nacional/volcan-poas-reabrira-al-publico-el-30-de-julio-tras-baja-en-actividad_389088). Activity picked up again in 2026. After a moderate eruption in late August, the volcano stayed at the "Warning" level according to the volcano observatory [OVSICORI](https://www.ovsicori.una.ac.cr/), and from Aug. 28 the park cut its daily capacity almost in half, from 2,052 to 1,064 visitors, [El Observador reported](https://observador.cr/volcan-poas-aumenta-su-actividad-reducen-a-la-mitad-el-aforo-del-parque-y-sera-obligatorio-usar-casco/). The crater lookout was limited to 56 people per 20-minute turn, and helmets became mandatory on the main open trails. The same day, the National Emergency Commission (CNE) declared a preventive green alert for the park, which stayed open under the stricter rules, [El Observador reported](https://observador.cr/cne-declara-alerta-verde-en-volcan-poas-por-aumento-de-sismos-erupciones-y-gases/). The CNE's alert is separate from OVSICORI's activity level. ## Planning a visit to Poás now The Jan. 29 reopening is history, not a promise about today. Before you go: - **Book ahead through SINAC's official [SICORE system](https://serviciosenlinea.sinac.go.cr/).** Poás tickets are sold online and capacity is limited. - **Check the volcano's status the day before** on OVSICORI's activity-level page or its crater webcams. - **Stick to the main road and open trails.** Don't try back roads or closed areas. Illegal entries are a real problem at Costa Rica's volcanoes, as SINAC's [count of 408 holiday trespassers](/news/sinac-408-unauthorized-park-entries/) showed. - **Go early.** Clouds often cover the crater by late morning.
