Northwest Bay is located just south of Parksville on Vancouver Island. It is a lovely place to go for a fossil day trip. Purchase a local map to help with directions. Turn east off the Island Highway onto Northwest Bay Road. Continue for 3 km and then turn left onto Wall Beach Road, which ends in a parking area up a short hill. Take the trail to the beach.
The first beds you'll encounter are yellow-brown sandstones with trigonid bivalves. Overlying these beds are fossiliferous, gritty blue-grey shales with bivalves, gastropods, ammonites and crustaceans. You’ll want to check the tide tables to arrive for low tide.
