SAN DIEGO (CNS) - The 25th annual Whale Watch and Intertidal Festival begins Saturday at Point Loma amid the most bountiful whale-watching season in recent memory.

The event at the Cabrillo National Monument celebrates the passage of gray whales on their annual migration from Alaskan waters to Mexico, where they give birth.

Biologists and regular whale watchers say the gray whales have been abundant this year.

A pod of about 10 orcas -- killer whales -- were spotted feeding off the Palos Verdes Peninsula in Los Angeles County, and off Dana Point in Orange County this past week.

The festival, which runs from 10 a.m. to 4:30 p.m. Saturday and Sunday, will include experts on gray whales, and talks about habitats, such as the tide pools at the park.
