There are quite a few publication about Costa Rica on Connect. Why not try to search the community for mentions of the place that you are interested in to find posts that have that name in the title, body of the post, or the location tag. Feel free to jump into these conversations and speak with Local Guides in/from there. You can start by checking the following publication by @delavegarcia called Traveling in Costa Rica’s nature.
I’m currently living in Costa Rica and I got this website from a local: https://quebuenlugar.com/. In my opinion it’s incredibly useful - you can look for particular places or activities and they list very useful info like required time, transportation, cost, difficulty, parking… basically everything (it’s in Spanish by default but you can change it to English if you want to).
