This was our 5th visit to Costa Rica and we have never spent any time in the Central Valley. When I asked my husband what else he wanted to do, he said he wanted to see more hummingbirds.
If you arrive between 8-9am and head to the hummingbird gardens, they let you hand feed the hummers. They land on your fingers. Sometimes three at a time. There are 26 kinds. It is crazy all of them flitting around. There are many rescued animals such as monkeys, others birds, big cats, frogs, butterflies, and more. As it is spring on cr, love is in the air and several of the critters are ready for love. The ocelots were courting as were a pair of macaws and the Jaguars. The ocelots were not fixed so maybe there is a mating program. Make sure you get your pic with the toucan. Also the staff at the frog exhibit might do something special if you are lucky. They love tips.
Be warned that there are a lot of steps to the waterfalls and elevations in general. We had the buffet lunch and it was ok. The arroz con leche was awesome. We ignore the advice to buy ponchos and regretted it, lol.
They brought out an is cart with live cows and you could get in the cart for pics. We tried the agua dulce and other treats at the casa.
It was an awesome experience. I am so glad we went.
