I've had a different experience every time that I've visited this place. I've tried lots of different activities: kayaking (a must-try), wandering through the mangroves and other places of profuse and enchanting nature. I've tried typical delicacies of the region too, most of which are based on seafood (tapado is a must-try, as is the fish, the shrimp sautéed in garlic, the breaded shrimp, and ceviche, etc.)
It would be no coincidence if this heavenly place was chosen by rich Guatemalans and foreigners as a peaceful retirement spot. It's an inexpensive area and a good environment to live in ... and it's very popular with tourists travelling to Guatemala.
Starting from the city which is named after the river, it is possible to go up the river to one of the most famous national monuments: Fort San Felipe. Here it's called the castle ( castillo ), a proud building which silently carries the memory of almost all of Guatemala's history: piracy and theft of indigenous resources for export.
NB: Not far from Río Dulce is Amatique Bay and its white beaches, blue-green sea, and water parks. An option for holidays with friends or with family.
