Explore The south The Hummingbird Highway Dangriga Hopkins Glover’s Reef Cockscomb Basin Wildlife Sanctuary Placencia The far south Punta Gorda Share Two kilometres past St Herman’s Cave, accessible from the highway or via a marked trail from the visitors’ centre, is Blue Hole National Park, centred on a beautiful pool whose cool turquoise waters are perfect for a refreshing dip. The “Hole” is actually a short stretch of underground river, whose course is revealed by a collapsed cavern. Other trails depart from here, including the Hummingbird Loop. The guided cave and rappelling trips run by Caves Branch Jungle Lodge aren’t cheap (822-2800, whttp://www.cavesbranch.com; from US$85 per person), but well worth it for the experience. Many of the caves contain Maya artefacts – burials, ceramics and carvings. The best independent guide to the area is Marcos Cucul, based in Belmopan (t 600-3116, w http://www.mayaguide.bz).
