Entry is to the left of the rock breakwater, on the sandy beach. Simply walk in and swim alongside the breakwater. As you swim, look for a large pipe. When you find this pipe, turn and follow it to its end (bearing ~225 degrees). At the end of the pipe make a 90-degree turn to your right. The remnants of the Malahat should be just a short swim away. The Malahat was a turn-of-the-century schooner, made famous as a rum runner during prohibition in the US. It used to run legal booze from Vancouver to California, where it would become a floating liquor store in international waters. Post-prohibition it became a logging ship, eventually being sunk in Powell River. Not much remains of the ship today, with the exception of a few ribs and some machinery. But the site is covered in life. Lingcod, octopi, wolf eels and more make their home here. An excellent and interesting dive. The Malahat is ~30m/100' long, and lies in 12m-18m (40'-60') of water. The wreck is located in the Malaspina Straight, so current may be an issue. Many people boat in this area - use a flag.
This dive is located in the town of Powell River. Take highway 101 (AKA Marine Ave) to the pulp mill and turn into the mill's access road. Immediately after you turn onto the access road it'll split - take the left-hand roadway. Follow this for ~1km. The dive site is at the bottom of the hill, beside the last small breakwater. There is a small "island" the road loops around - this is a good place to park your vehicle.
