The Acantilados de Maro-Cerro Gordo natural park stretches four kilometres along Andalusia's eastern Costa del Sol, a protected corridor of dolomitic limestone cliffs rising sixty metres above translucent Mediterranean water. Designated in 1989 under regional conservation law, the park shelters seventeen endemic plant species and nesting colonies of shearwaters that return each spring to cavities carved by millennia of wave action. The cliffs were shaped during the Jurassic period, their grey-white strata folded and faulted by tectonic compression, then sculpted into overhangs, sea caves, and tidal arches by the relentless eastward Alborán current. At the park's western edge, a seasonal cascade threads down the cliff face from an inland aquifer, visible only from the sea. The waterfall flows strongest between November and May, fed by winter rains that percolate through porous limestone and emerge at a spring fifty-three metres above the waterline. By late summer the flow diminishes to a trickle, leaving mineral streaks on the rock and pools of brackish water at the base. The feature has no official name on regional maps; locals and tour operators call it simply la cascada de Maro, anchoring it to the whitewashed village perched on the clifftop three hundred metres inland. Kayak routes along the Maro-Cerro Gordo coast became commercially viable in the early 2000s, after the Junta de Andalucía formalised access rules for non-motorised watercraft. Operators launch from Playa de Burriana in Nerja, paddling east past Cala del Cañuelo and Playa del Molino de Papel before reaching the waterfall zone. The park permits no motorised vessels within two hundred metres of the cliffs, preserving acoustic calm and protecting the shallow reefs that fringe the shoreline. Water clarity averages fifteen to twenty metres during the calmer months, revealing Posidonia oceanica meadows that anchor sediment and provide nursery habitat for bream and grouper. Today the maro waterfall kayak tour anchors Nerja's adventure tourism calendar, drawing paddlers from Madrid, Seville, and the crowded resorts of the western Costa del Sol. The park receives an estimated eighteen thousand kayak visits annually, concentrated between April and October when sea conditions permit safe passage. Guides brief participants on the park's fragile ecology and enforce no-touch protocols for the underwater meadows. The route remains entirely coastal, accessible to novices willing to paddle three to four kilometres in open water. No constructed trail reaches the waterfall from land; the cliff face is vertical and the interior scrubland designated strictly off-limits to foot traffic, making the kayak the only practical conveyance to the cascade.
