More ways to explore the area's outdoor wonders
The boat slips out of Bahías de Huatulco and the coastline thins into open Pacific. Salted wind tugs at your hat while a marine biologist scans the horizon; dolphins break the surface in tight arcs and, in winter months, spouts announce long-distance travelers—humpback whales—punching through the swell. The water here is warm and glassy between reef outcrops, inviting the group to don masks and fins and drop into clear pockets where parrotfish and banded angelfish patrol coral ledges.
