We lucked out when I happened to ask our bus driver which direction it was to walk. He spook no English, but I got out of him that we shouldn't walk and he'd give us a ride for just a few cents. We gladly went with him. The sea lions were so amazing! There were thousands of them. Big, small, happy, sleepy, and angry. It was so interesting to watch them interact, feed, fight, mate, etc.
We're glad we didn't pay an arm and a leg in Puerto Madryn to see the same thing. This cost us $1.50 or something crazy like that. If we hadn't got a ride and had walked we wouldn't have gotten to see as many sea lions because when we were leaving some workmen were just starting to stain the deck walkway on the cliff that you use to access the sea lions so we didn't get to stay as long as we would have like but Brian showed them by accidentally knocking over the can of stain when we were leaving - oops.
So, we went back to the beach and took a nap. When we woke up, the tide had gone way out and hundreds of natural swimming pools had formed within the rock now exposed from the low tide. You'll have to look at the pictures to understand. This is what we had read about and what all the locals love! We went into a couple of them and swam. The water temp was so great - very relaxing!
The second day we were in the Viedma area we took a bus with all the locals out to a small town called La Loberia where there is a beautiful beach on the Atlantic Ocean at the bottom of a huge cliff lining the coast. 3km down the road from the beach is a huge sea lion colony.
