Nice quick boat trip. Especially the view on the massive rock right east of the beach is fascinating due to the rocks structural formation. However nothing to exciting. The beach offers refreshments which are alright.
near the town of San Martin de los Andes there is a beach called Quila Quina which is a National Park.
It not accessible without car. the ride is on dirt road on mountain side.
take about 30 min to get there.
The site is nice and the views are beautiful.
I wouldn't go there again...as it is not that...
