The Mountain Top Park Hotel is great, located at the highest point of Manuel Antonio, you have a spectacular 360 view. The rooms are very clean, good size and again, have an amazing view.
They have 4 pathways throughout the huge property where you can see tons of wild animals. Surprisingly, they also have 8 hanging bridges across the whole property (and I believe also ziplines). You can do a free guided tour (twice a day; 7am or 9:15am) or explore the paths and hanging bridges on your own. The guided tour was great, we saw Toucans, Capuchin monkeys, frogs and more during the 1.5 hours tour.
The included breakfast is really good (fruits, cereal, juices, eggs, toast, rice & beans, sausage and more) and is from 7am to 9am. The restaurant has Happy Hour and good food but the best is the ocean view and sunset you can see from it.
The staff is really friendly, helpful and striving to make your stay great.
Overall a very cool experience and a very special property, that I would certainly book again.
