Exploring Vancouver Island – Botanical Beach

I’ll share a little secret –  I can’t go near the ocean without scavenging the beach and rocks for signs of sea life, identifying the sea stars and mollusks I can remember from my days as a Vancouver Aquarium volunteer, checking my trusty guide to identify those I can’t.  Naturally, Botanical Beach would find its way onto the “must see” list when visiting Vancouver Island.

At the head of the Juan de Fuca Marine Trail , just south of Port Renfrew, is a sandstone shelf that has been carved out by boulders and sculpted by the tides to create a landscape of natural pools.  These pools, accessible when the tide ebbs, contain a microcosm of colourful sea life that will enthral young and old alike.  My inner child awakens as I pick my way across the rock and peer into the pools, excited in my search for the elusive nudibranch or gumboot chiton.

Tidal Shelf and Pools

The unique geology drew biologists to the region and the University of Minnesota established a marine station at the site from 1900 to 1907 for the study of marine algae.  Josephine Tilden, the first female scientist on staff at the University, funded the station on donated land.  Her work at Botanical Beach led to the first published American scientific work on marine algae.  Established as a Class A park in 1989 and afforded the highest level of of protection, Botanical Beach continues to be used by universities for field study and research.

The mollusks, crustaceans and plants that live here have adapted to the rugged environment.  Purple sea urchins dig holes in the soft sandstone to protect against the rushing tides.  Gooseneck barnacles and blue mussels cling to the edges, closed tight against the air and sun.  Sculpins zip along the bottom, hiding in the shadows and blending with the  rock.  Crabs scuttle across the pools and bury themselves under stones, in cracks and crevices.

Urchins and Chiton

Sandpipers join the curious, their muted beige and white blending with the rock, their high-pitched chirps barely audible amid the crash of the waves.  They flit along the sandstone, their needle like beaks sifting through the kelp and water for the small worms, snails and insects that make up their diet.  Overhead, seagulls and cormorants circle, searching for their next meal.

Beyond the shelf, harbour seals bob in the swell, their round heads peering at the visitors to the rocky ledge before slipping back below the waves.  On a good day, you might even catch a glimpse of a grey whale or orca slicing through the water.

Scavenging Sandpipers

Botanical Beach provides the best opportunity to explore the Pacific intertidal zone up close, but is not the only draw.  The area surrounding Port Renfrew is also home to world class hiking trails (the West Coast Trail starts here), sandy beaches and some of the largest trees in Canada, including Canada’s Gnarliest Tree.

A short drive from Victoria, a trip to Botanical Beach and surrounding area makes a perfect day trip for those wanting to explore the wild and wonderful British Columbia coastline.

If you go:

  • Check the tide tables. The best time to view the pools is when low tide is 1.2 meters or less
  • Wear water shoes with a good gripping sole – the barnacles and periwinkle snails are hard on bare feet and the exposed rock can be slippery
  • NEVER turn your back on the tide – it can rise quickly and rogue waves can appear suddenly
  • Know where you are on the shelf in location to an escape route if the tide begins to rise
  • Keep children away from the shelf ledge
  • Please keep hands and feet out of the pools to protect the pools from contamination
  • Pack out your garbage
