I will be traveling alone to Costa Rica this June and will be there for a week. I'm 27 years old and I'm pretty active. Some of the activities in Costa Rica that I'm interested in doing include mountain biking, white water rafting and zip lining through the rain forest. Basically I'm wondering whether it is better to book these activities separately or as part of a multi-day tour package. I've noticed that some of the all-inclusive tours tend to cater towards older adults who might be less inclined to seek adventure. I actually want to experience the culture and I really have no interest in being pampered or "nickled and dimed" at some fancy resort. Is it better to have all these tours booked ahead of time or should I play it be ear and book upon arrival? Any tips or advice is appreciated. Also, if anyone has any adventure tour suggestions that involve camping, biking, etc that might be up my alley let me know. Thanks.
