What to expect
The sea need not be just the backdrop to lunch in Ilo. Punta Coles has a visitor circuit with wildlife viewpoints. Bring something to help you look from a distance: the interesting activity may not be beside the path. Animals decide what you see, not a checklist written at home.
How it fits into a journey
Make it a separate nature outing from Ilo, allowing for the return journey. Combine Punta Coles with your coastal stay.
