Majestic offers guided day trips, overnight trips, and kayak rentals from their harbor-side location on Vancouver Island.
If you're on the west coast of Vancouver Island, you must get on the water! Majestic does a great job of guided kayak tours for families. Our kids ages 7-12 loved it. We opted simply for the harbor tour, which is just a few hours and stays out of the open water. We worried paddling the harbor would be boring, but not at all! We saw eagles and fish and sea stars, plus other wildlife, and our kids had a blast in the kayaks.
The best thing about Majestic are their guides. Ours was fantastic, and engaged the kids, listened to them, and showed them much around the harbor. Snacks and water is provided, but there are no bathrooms once you're on the water! They depart rain or shine, but will provide 'skirts' that block the rain and water, so we were very comfortable.
