From each operator's own website, checked October 22, 2026. How we compare.

PR-10 at Km 75, Caguana, Morovis and Dorado

Cueva Ventana sits on PR-10 at Km 75 in Hato Viejo, Arecibo, about 75 minutes from San Juan on PR-22, according to Discover Puerto Rico. Wikipedia places the trailhead beside a Puma Energy gas station on PR-10 and says the cave can be seen from PR-123 across the valley. The cave and the land around it are privately owned. Aventura Cueva Ventana runs the tours and sells a $175 per person SUV package that collects guests from any hotel or lodging on the island for groups of three to five.

The other three operators work from different towns. Tanama River Adventures meets at Road 111, Km 48.4, in Barrio Caguana, Utuado, where its store opens at 7:30 am and every tour leaves at 8:30 am. CABACOOP, the cooperative behind the Las Cabachuelas project, lists its office at 32 Calle Baldorioty, corner of Rafael Torres, in Morovis, and gives no separate meeting point. Caribe Adventures gathers cave tubers at Doramar Plaza in Dorado at 8 am, about 20 minutes from San Juan by Uber by its estimate. From there the group drives to caves at Charco Azul in Vega Baja and Arenales.

The window above the Río Grande de Arecibo

Cueva Ventana opens onto the Río Grande de Arecibo valley from the top of a limestone cliff, which the operator puts at 700 ft. Discover Puerto Rico says Cerro Punta in Jayuya, the island's highest peak, is sometimes visible on a clear day. The route passes stalactites, stalagmites, tunnels and smaller caves, resident bats, native ficus and cupey trees, and Taíno petroglyphs of gods, human figures and animals. The operator's walking tour lasts about 90 minutes in all, with roughly 45 minutes of walking; the tourism board gives 45 minutes to an hour of hiking. Some passages are fully dark, so the flashlight matters.

Tanama River Adventures' Mukaro Cave Tour follows the Tanamá River through Cueva del Arco and other caverns. The hike covers about 3.5 miles, close to 4 by the operator's own notice, and takes 3.5 hours or more. The river has no rapids, and the day mixes forest trails, river trekking, waterfalls, spring water and an underground river, with optional jumps. The operator points out ocean-floor fossils, crystals, stalactites and stalagmites in the rock. Its Butterfly Tour adds a 120 ft rappel inside a cavern over 3 to 4 hours, and the Tarzan Tour a 250 ft rappel in about 4 hours.

Las Cabachuelas in Morovis holds more than 60 caves, caverns and ravines with Taíno art and several endangered species, Discover Puerto Rico says. CABACOOP's Regular tour covers three caves in 3 to 4 hours and the Intermedio two caves and a shelter. The Corto is a hike and one cave in 1 to 2 hours, and the Nocturno does the same at night in 2 to 3 hours. Caribe Adventures' cave tubing runs from 8 am to about 1 pm with tubing on calm river and cave water, hiking, climbing over rough ground, waterfalls and cliff jumping. Río Camuy Cave Park, the island's largest cave, is temporarily closed.

Helmets, 240 lb limits and 8:30 am

Cueva Ventana hands out a helmet and flashlight and makes both mandatory. Children under 3 are not allowed, a rule the operator attributes to new insurance requirements; Discover Puerto Rico's article (August 20, 2026) still says under 5. Wear comfortable clothes and shoes, the tourism board says, and call 787-322-3554 beforehand to check that the site is open and the weather is not a problem. Tanama River Adventures requires good physical condition on every trip, caps riders at 240 lb and warns that about 20 minutes of the Mukaro hike is a steep, slippery descent.

Ages rise with the rope work. Tanama River Adventures takes children from 8 on the Mukaro tour, 14 on the 120 ft rappel and 18 on the 250 ft rappel, and asks everyone to arrive by 8:30 am. CABACOOP's Regular tour starts at age 8 and the Intermedio at 12. Caribe Adventures takes ages 13 to 65 up to 260 lb, requires closed shoes, rates the day moderate to challenging and advises against it for anyone whose surgery limits hiking or climbing. Discover Puerto Rico says every Tanamá canyon trip needs participants in excellent physical condition.

Tanama River Adventures refunds 100% or gives full credit when it cancels, for weather or any other reason. Guests who cancel with 72 hours' notice get 75% back, inside 72 hours 50%, and same-day cancellations and no-shows pay in full. Cueva del Viento in Guajataca State Forest, reached from the ranger station at Km 9 on Route 446, has no lighting or guardrails. The tourism board advises sturdy shoes and a flashlight for anyone visiting on their own.

Cueva Ventana at $29, Tanamá rappels to $129

Aventura Cueva Ventana is the cheapest and shortest: $29 plus IVU per adult and $10 plus IVU for ages 3 to 10 for about 90 minutes, booked through FareHarbor. Its UTV VIP Tour carries up to four per vehicle along a dirt and stone track to the cave, with water and snacks, at a price shown only in the booking calendar. The $175 per person SUV package covers the ticket, helmet, flashlight and a private black SUV from any hotel, three to five guests. Discover Puerto Rico quotes a $19 non-resident fee and 10 am to 4 pm hours that do not match the operator's pages.

Tanama River Adventures charges $65 per adult and $59 for ages 8 to 12 on the Mukaro Cave Tour, mornings only from Utuado. The Butterfly Tour with its 120 ft rappel is $95 and the Tarzan Tour's 250 ft drop $129. Its office is closed on Sundays and Wednesdays. CABACOOP prices the Regular and Intermedio tours at $55 and the Corto, Nocturno and Cristales at $40. A VIP tour for up to five with lunch is priced on request, and a rappelling tour is marked coming soon. Caribe Adventures' $79 cave tubing books by phone or WhatsApp, with no online checkout and no published cancellation terms.

Before you book

  • Call Cueva Ventana at 787-322-3554 before driving out. Discover Puerto Rico says to confirm the site is receiving visitors and that weather is not a factor.
  • Be at Tanama River Adventures' store in Caguana by 8:30 am. All its tours leave then, mornings only, and no-shows pay the full price.
  • Wear closed shoes for the Caribe Adventures tubing day; the operator requires them, and the trip includes climbing over rough ground and cliff jumps.
  • Bring your own flashlight and sturdy shoes to Cueva del Viento in Guajataca State Forest, which has no lighting or guardrails, Discover Puerto Rico says.
  • Getting there. Discover Puerto Rico puts Cueva Ventana about 75 minutes from San Juan by car via PR-22, at PR-10 Km 75 in Hato Viejo, Arecibo. Caribe Adventures' meeting point in Dorado is about 20 minutes from San Juan by Uber, the operator says.
