Celebrating the area’s unique marine ecosystem, this masterpiece brings an artistic sensitivity to extensive scientific research. There are exhibits on the breeding habits of right whales, dolphin sounds and southern-elephant-seal harems, a touch-friendly tide pool and more. The building includes a three-story tower and library, with the top featuring glass walls and comfy couches for reading. Bring your binoculars: whales may be spotted from here. It’s an enjoyable 40-minute walk or 15-minute bike ride along the costanera to the EcoCentro. Shuttles run three times daily from the tourist office on Av Roca, or you can catch a Línea 2 bus to the last stop and walk 1km.
