This time last year I was on expedition in Belize’s Chiquibul National Park and Forest Reserve. I’d been tasked by Friends for Conservation and development (FCD), the co-managers of the Chiquibul National Park and Chiquibul Cave System with developing a road map for the sustainable tourism development of the vast Chiquibul Forest. As part of the project TOR I had to explore some of the key geophysical features within the Chiquibul Forest. For over 20 years I’d dreamed of exploring the Chiquibul Cave System (CCS), the largest known cave network in Central America. Together with 2 rangers and a locally based environmental researcher Jan Meerman we headed off from FCD’s Las Cuevas Research Station to Puente Natural and from there floated down the Chiquibul River and through the uncharted Chiquibul Gorge. Pulling out of the Chiquibul River at Rasumadero we trekked with heavy packs to the Kabal entrance of the CCS.
