Masaya is a city in Nicaragua
Masaya is the second most important city in Nicaragua. From the airport you can take a taxi cab that could charge you $20-30. Also, all the cities in Nicaragua have buses that take you directly to Masaya. There are also public minivans known as microbuses that will take you from Managua to Masaya for a bit less than $1.
Also, Masaya has several churches built in the colonial period and in the 19th century. Someof the churches are: Nuestra Senora de la Asuncion, San Jeronimo, San Juan, San Miguel, etc.
Masaya is famous for a really big mercado that has great smells and everything in abundance.
I would definitely recommend getting in touch with Maria-Jose at Masaya Tours. We took a day trip with her and it was a fantastic experience for a very reasonable price. Since she grew up in the area you can tell that she lives and breathes Masaya and Granada. She was even able to sort out a few deals becuase of her local knowledge and bartering skills at the market.
My highlight had to be swimming in the beuatiful lagoon of Masaya , which we found was not available through other tour opeators that only offered a view of it from afar. With Maria-Jose we were able to find a route down to the lagoon itself and swim in the crystal clear secluded waters. Other activities included visting the harrowing fort up in the mountains and learning about the rich history of the area fom a local's point of view.
Like a lot of other tours we visited the active volcano, but it really enriches your experience when you can hear about the myths and legends that go the sights - the cultural significance and the local stories of sacifices to the volcano
In the evening we made our way to Masaya maket and Maria-Jose took us to a local eatery tucked away in the side streets - probable the biggest, juiciset pork steak and baked plantain I've ever had - before joining the locals at a night festival where we watched great authentic Nicaraguan music and dance.
I cannot recommend using Marai-Jose enough as a guide. With her you get a fully authentic experience and it's obvious that she has a real passion for her home town. Even though we were on a tight budget during our travels we found our day with Maria-Jose to be extremely good value for money.
