Guatemala  has a number of white-water rivers with rapids ranging from Class II–VI (Class VI being unpassable waterfalls). The most popular river for rafting and kayaking is the Río Cahabón , found in the region of Las Verapaces. It features some of Central America’s finest stretches of white water complemented by jungles, caves, hot springs, and waterfalls.
Also in the Verapaces region, the Río Candelaria winds its way through its namesake cave system and is a great place for river tubing and kayaking, allowing the chance to explore these fascinating caves to their full potential.
Another worthy white-water excursion is Petén ’s Río Chiquibul, at the eastern end of the department near the Belize border. Although the rapids are not quite as exhilarating as those on the Cahabón, it’s highly attractive for its jungle-lined riverbanks and proximity to Mayan sites such as Tikal  and Yaxhá .
For more sedate kayaking on ocean kayaks, Lake Petén Itzá  and Lake Atitlán are good bets.
It’s possible to scuba dive off the Caribbean Coast near Punta de Manabique Wildlife Refuge , though you’re probably better off heading just a bit farther north to the exquisite diving at the Zapotillo Cayes  part of the Belize Barrier Reef. Several outfitters arrange trips from Lívingston .
Scuba diving is also a popular activity in Lake Atitlán , where you might even be able to feel the heat emanating from underwater lava flows in this still-active volcanic region. Another peculiarity of diving here is that the lake is at a rather high altitude just over 1,500 meters (5,000 feet), adding another variable to the mix.
An emerging surfing scene is centered around the Pacific Coast village of Sipacate , which enjoys excellent breaks. Iztapa  also reportedly has good breaks, as does Monterrico . A useful website for checking out Guatemala’s surf scene is www.surfinguatemala.com .
Boaters will find marinas on both Guatemalan coasts. On the Pacific, a new marina was built with partial backing from Dutch interests near the aging port facilities of Champerico . Farther east, the Marina Pez Vela caters to sportfishing boats and is adjacent to the Puerto Quetzal  Cruise Ship Terminal. It has restaurants and good tourism infrastructure. On the Caribbean Coast, you’ll find many boats traveling up the Río Dulce from the Caribbean Coast and docking at any of a number of marinas in the river’s namesake town.
