The National Alliance on Mental Illness, a mental health organization dedicated to improving the lives of those affected by mental illnesses, will host a Hawai'i walk on Saturday.

The walk will take place from 8 a.m. to 2 p.m., beginning and finishing at Honolulu Hale. The Royal Hawaiian Band will provide music.

Prospective participants should register ahead of time, but they also may register on the spot, organizers said.
