I lived in Mexico and visited many countries in Latin America and I can tell you that Costa Rica was by far the cleanest one and also the one with the highest protection of the environment and their incredible natural beauty and biodiversity. Almost 1/3 of the country consists of national park and natural reserves.
As for the heat... I visited Costa Rica in September and it felt much colder and more refreshing there than the scorching Yucatan where we lived back then ;)
Yes, that's true. Today I had a small adventure with my little girl: trying out the public transport (local bus) to go to the next town with my rather poor spanish 🙈, and my phone battery was running out 😝. It's especially exciting cos we're now at the place which is not typical for tourism, so there is only one bus for every 3 hours 😝.
But along the way I could really confirm that Costa Rica is clean and so green everywhere.
The way how public transportation work remind me of my own home country:Indonesia, but how the people here take care of the beauty of their country.... There are so much for my fellow countrymen to learn 😊.
