During this two and a half hour navigation, you will be able to discover not only the most iconic of the Capilla de Mármol Nature Sanctuary but also the Puerto Sánchez area. The experience begins at our meeting point at the Aoni Expeditions office, and then we head to the embarkation point and first head to the eastern sector, where we will find the stranded boats that are part of the story told in Puerto Cristal; the marble caves belonging to the sector, before starting to head south and marvel at the Chapel, Cathedral, and marble formations of Puerto Río Tranquilo.
