Maratón Acuática San Pedro — 20K

San Pedro offers a range of stays, from traditional camping sites along the riverfront to boutique hotels near the harbor and local fishing cabins. Expect prices to fluctuate between $50 and $150 per night depending on proximity to the water and service level. For those preferring direct access to the starting area, the facilities maintained by the local nautical clubs often provide the most practical base for early morning departures.

The weekend provides opportunities to explore the region's unique geography and history. Visitors can engage in kayak or SUP excursions through the intricate Paraná Delta channels, or visit the local Paleontology Museum to view the fossil record of the surrounding riverbanks. Guided tours of the ARA Irigoyen museum ship and short treks along the coastal barranca cliffs are also accessible, offering a broader perspective on the landscape traversed during the marathon.
