The capital of the Entre Ríos Province can be reached from Santa Fe via the Hernandarias Tunnel under the River Paraná. East of Paraná, near the border with Uruguay, Concepción del Uruguay has numerous spas and river beaches (on the River Uruguay), notably at Banco Pelay and Itapo. The nearby city of Gualeguaychu is famous for its carnival, which rivals those of Rio and Bahía in Brazil. Further north, some 360km (225 miles) from Buenos Aires, lies the El Palmar National Park, whose main attractions are the old yatay palms, some of which are nearly 800 years old.
