Me and my boyfriend are going to explore Costa Rica in december (approximately 7-14th of december +/- a couple of days). Because of the limited time, we need to decide which part of Costa Rica we want to explore. We are currently thinking about visiting Monteverde Cloud Forest (probably flying to and from San José) and then continue to Guanacaste to explore their beaches and snorkeling.
We have an average budget (not planning on staying at luxurious hotels, but neither cheap hostel dorms). What we mainly want to get out of this trip is: relaxing at beaches, discovering nature, kayaking and snorkeling. Are there any places that we NEED to visit? What areas should we avoid (especially considering the level of tourism, we don't want something too touristy).
Thank you very much for your help!
