The salt-kissed air of Lisbon’s Parque das Nações always does something to me—it turns ordinary days into adventures, and the Parque das Nações Oceanarium has long been the crown jewel of that neighborhood. But whispers began circulating well before 2026: something monumental was brewing. I’d spent countless afternoons there with my niece, Ella, watching her gasp at the giant ocean tanks, but this time, when I arrived in early March for a sneak preview, I felt the thrill of discovery all over again. The renovations aren’t just tweaks; they’re a reimagining of how we connect with the marine world, and the nine new attractions revealed this year alone have me rebooking my calendar faster than you can say “manta ray.”
At €22 for adults (€18 for seniors/students), it’s a bump from the old €15, but when you see the engineering—nearly 85 meters of curved glass, lighting that makes every flicker of a lemon shark’s fin look like a dance performed by nature itself—the cost evaporates. I stood there, heart pounding, as a school of hammerheads glided overhead. One brushed so close I felt the water’s current; the acoustic designers clearly understood that silence amplifies awe. They’ve even added optional “shark whisperer” audio guides for €5 more, narrated by a marine biologist who sounds like she’s whispering secrets from the deep. Book early; the tunnel caps at 200 visitors per slot.
The “Ocean Explorers Lab” lets kids (and the kids-at-heart) collect virtual plankton samples, then release them into a projected ecosystem. My cousin’s daughter, Lila, spent an hour “training” a digital whale to migrate, giggling as it “ignored” her commands. Nearby, the “Touch the Tides” pool features warm seawater and real barnacles, sea stars, and small rays—gloved handlers can gently guide touch sessions. Staff are trained to keep lines moving, but on a Tuesday morning last month, we had the whole space to ourselves. Pro tip: arrive right when the Parque das Nações Oceanarium 2026 opening hours and preview event registration begin. The preview night in February (registration via the Oceanarium’s site, 200 slots worldwide) offered entry an hour before official opening, and the hush before dawn felt sacred. We watched cleaners vacuum the tanks while staff prepped feeding tools—it’s the kind of behind-the-scenes moment you’ll never find on a postcard.
Three daily sessions for dolphins and pilot whales, each with a different theme: “Communication,” “Ecology,” and “Myth vs. Reality.” I attended the 11 a.m. session; the trainer spoke about the whales’ ability to hear each other from eight miles apart while feeding fish laced with harmless, glowing markers. Kids can request to help “spot” the fish—a rarity in most aquariums. The schedule is posted on digital boards throughout the venue, but app notifications are spot-on. If you hate crowds, aim for the 9 a.m. slot; the best time to visit Parque das Nações Oceanarium Lisbon 2026 to avoid crowds is unequivocally before 10 a.m. or after 4 p.m. on weekdays. Weekends? Brace yourself. The new attractions have doubled peak-hour footfall.
No flash needed: use long-exposure (ISO 800, tripod) to capture the otherworldly blue glow. I brought a small handheld light diffuser—it softened the ambient light and made the blue swirls look like liquid starlight. The tank is dimly lit, so wear comfortable shoes; you’ll want to linger.
Ramps with gentle gradients, wide doorways, tactile pathways lined with braille explanations in Portuguese and English, voice-announced elevators, and quiet rooms near the entrance ensure comfort for every guest. I spoke with Marta, a visitor from Porto who uses a wheelchair, and she praised the soundproofed “quiet rooms”—spaces where visitors can rest or recharge. Even the shark tunnel has a raised platform for those who can’t comfortably navigate the slight slope.
At €35, you get unlimited access to both sites plus a guided audio tour at Vasco da Gama. The mall itself—a sleek, futuristic space housing brands from Louis Vuitton to FNAC—deserves more than a quick walkthrough. Its address, Av. das Nações Unidas, 1749-066 Lisboa, is just a five-minute walk from the Oceanarium’s Estrada da Costa, 1990-211 Lisboa. I spent an hour browsing the science exhibits at the Vasco da Gama’s “Future of Travel” installation, then walked back enjoying the sunset over the Tagus River.
Take the metro Linee 5 (yellow) from Aeroporto station to Alameda, then switch to the purple Linee 8 to Parque das Nações—25 minutes, €2.60 with a Viva Viagem card. Taxis queue outside the airport, but Uber and Lift are often cheaper.
Dimmed lights, ambient ocean sounds, and a glass of Portuguese Vinho Verde included in the €45 tour. I joined a tour last month; we sipped wine while a biologist discussed symbiotic relationships in the coral reef tank. Tours are limited to 30 people and sell out within hours. Booking opens three months in advance.
Whether you’re a local or first-time visitor, 2026’s renovations promise deeper connections—with the sea and with yourself. Mark your calendars, pack comfortable shoes, and prepare to see the sea—and yourself—in a whole new light.
