Punta del Este's Antithesis - Punta Del Diablo
Surfs Up! Many of the surrounding beaches have good clean breaks.
There are numerous paths to hike in the parks as well.
Fortaleza de Santa Teresa – Built in 1762 by the Portuguese it was then later taken by the Spanish while the two empires wrestled over the spoils of trade routes and territories in the New World. The Fort was restored in 1928.
Laguna Negra – A birdwatchers paradise. The immense lake is great for boat trips out and the surrounding swamplands are home to all manner of migrating birds.
Santa Teresa National Park – 3000 hectares of forested land ( 2 million trees!) on the site of one of the most important battles for Uruguay’s independence and containing flora and fauna from five continents. 60km of walking trails and desolate beaches.
Just wander through the winding streets of colourful wooden houses or stroll down to the fishing boats when the locals bring in the day's catch.

I'm hanging out in Punta del Diablo now - highly recommend a visit, especially now that it's shoulder season. In December and January this place is apparently a mad house but now the weather is still good and it's mas tranquilo.
