Tour with Morinda Eco Tours. It was the best trip I did in Surinam. Maybe the conditions were not so good as some can expect but that was not the most important thing on that trip. Only 5 people were on that tour. Our guide was also a cook for us. He made very good meals. And realy was taking care for us for the whole two-day-trip.
You can find Morinda Eco Tours at the post office at Kerkplein, or at
