We used Eco tur. Luanda is very pricey and NOT tourism friendly. The sites we saw on the city tour- click on my reviews for all the sites seen are not overly thrilling. You can walk along the promenade to the fort- about 45 minutes each way and if it is hot it is not pleasant. The tour we had was arranged as a group on the ship using Cruise Critics group. Paul wanted groups not individuals. Even with groups it was over $100US/person for a half day tour . The ship wanted $200-$500 for city tours - highway robbery in my opinion. We toured in a caravan of vehicles and we were told we could get a police escort if need be which we did not. Shopping is very poor- No real 'shops', a few rustic road side stands selling poorly crafted hunks of wood for high prices and not interested in bartaring. If you are going to other countries on your itinerary- Namibia, Sao Tome for example, the craft works are far superior and much better pricing. Touristy stuff like t-shirts, ball caps, fridge magnets - we could not find and we were looking. On our ship, no one else found these types of goods. We paid the high bucks- kind of upset at paying the price but glad we did as we can say we have seen the sites of Luanda, and will not go back.
