If you haven't seen penguins, go! The fishing boats (5000 pesos each) out to the islands go at random times, but sit and have a drink, and you might get on one. Minimum 10 people.
We stayed in a cabana, 50m from the seashore. Could hear the waves all night and there was a lovely patio to sit out on. The birdlife all along the beach was superb.
firstname.lastname@example.org or email@example.com to book a cabana. We spent weeks trying to find these!
The cabanas were basically equipped (no kitchen knife in the one we had and only one wine glass) but were beautiful with the bedroom overlooking the Pacific and a lovely ensuite bathroom. Electricity is from a single solar panel and you can't plug anything extra in. Bring matches, a penknife (with a tin and bottle opener) and a torch. The bed linen was very luxurious. Don't expect hot water all the time or a state of the art shower - you are in the middle of nowhere!
If you are bus/taxiing in, bring all your food with you and don't expect to buy anything in the Park. The restaurants in the fishing village are good and very reasonable but if you want breakfast and to do your own thing, bring it with you!
A car would have been useful, but as we were only there for 3 nights, we could do all the local walks.
We were handed a tsunami leaflet on arrival and this was somewhat unnerving.
Chanaral is heavily polluted and we are glad we didn't stop there for long.
