There wasn't one thing I enjoyed most about the internship because I enjoyed it all so much. I definitely grew as a person and was able to learn so much about myself and what I might want to do in the future. I met so many amazing people and miss it so much. It was an experience that I will never forget and I am so thankful that I had the opportunity to do it.
I most enjoyed the hands-on fieldwork, particularly participating in coral nursery maintenance and reef monitoring dives, where I could see the direct impact of conservation efforts. This internship strengthened my technical skills in data collection, observation, and teamwork, while also improving my adaptability and cross-cultural communication. Professionally, it clarified my career goals in marine biology and conservation by connecting classroom knowledge to real-world application. On a personal level, it increased my confidence, patience, and appreciation for community-based environmental work and allowed me to make some great friends and see all the amazing things that Costa Rica has to offer.
