You can see the rocks from where you'll be staying.
You can also get a Panga to take you out. Will run about $180.00 for six hours or so of fishing. Getting out on a boat for a day puts a whole different spin on the area. We'll worth it in my opinion.
I have a guy I've fished with on multiple trips in the past. Let me know if you'd like his contact info.

If you fish the beach, figure around 10:00 for quitting time max and start thinking cervezas and pool time.
I've caught a number of small roosters right where the dry arroyo dumps in just north of the Peublo Bonito Rose.
There is kind of a trench there that gets washed out after big rains. You'll notice a lot fish traveling the beach just outside where the surf breaks and the drop-off begins.
