It depends when are you planning to go, and who are you going with.
In summer, you can visit Sonora Resort

I went their for my honeymoon, it's the most amazing and the most secluded spa resort. You can go fishing, whale watching, Kayaking. There's plenty of trails and you get to choose to take the bear whistle or the 3 golden retrievers. The 3 retrievers are trained to wait for you but will disappear to do their own things every so often. Take a cooking class or do sports, cuddle up to a movie at their private movie theatre.
It's a magical place that I didn't know existed living in Vancouver for 18 years.
Reachable only by helicopter or seaplane.
Cheers,
Sunny
