For a more active Telegraph Cove experience, consider a kayaking adventure. This five hour guided kayak trip offers a chance to explore Johnstone Strait in a much more eco-friendly (and quiet) way.
Learn about the abundant marine life in this area and potentially see humpback whales, orcas, black bears, seals, sea lions, otters, dolphins and more! (sightings of large marine mammals not guaranteed)
Compared to a Zodiac or boat tour, you'll get a better insight into the intricacies of the intertidal zone and see smaller creatures and plants. Kayaking is, of course, a lot more active as well but still very approachable for first timers.
The linked tour (below) is run by a very well regarded local kayak tour operator.
***January 2025 update - part of Telegraph Cove was destroyed by fire on 31st December 2024. North Island Kayak has confirmed that they will be operating in summer 2025.**
