Orca Books publishes some of the most popular day hiking guidebooks.
Hiking Trails 1 (Victoria area)
Hiking Trails 2 (south/central Vancouver Island)
Hiking Trails 3 (northern Vancouver Island)
I’ve been using Trails 2. It’s the 9th edition (2010) and has been well tested.
Maps could be better. But the information provided is clear and succinct.
