We highly recommend a day trip to Anyanui, a market square on the opposite mainland. Until recently you could make this trip with the big ferry of the Volta River Authority. The ferry is currently not in operation because of the steady natural change of the Estuary System of the Volta River.
But there is also a very good opportunity to go by Trotro boat to Anyanui. Let the staff of the EZIME Guesthouse explain how to get there (10 minutes walk past the Ada Foah market square, to Christians Fresh Fish Shop, turn left to the river). Once there, you will need time, as the boats will not leave until enough guests are on board. This is a scenic trip with some short stops at small islands in the estuary and at the distant shore and along impressive mangrove swamps to the village of Anyanui. There is a big market where cut mangrove, used as fuel wood, are sold and shipped. In Anyanui, you have the opportunity to eat and drink.
The trip costs one way about 5 Cedis and it takes about half an hour. You may also want to continue the tour for a further exploration of the country in the direction of Keta by a Trotro or taxi. However, if you want to return same day, you should be back at the boat dock in Anyanui at the latest at 4pm to ensure that you reach Ada Foah before the dark.
This excursion has particularly enjoyed guests at the EZIME Guesthouse. But beware: this tour offers hardly any shade and it can get hot. With the right equipment it is no problem (hat, sun cream, water bottle not forgotten).
The ferry to Akuse up the Volta River still leaves on Mondays and returns Tuesdays.
