Short answer: Howe Sound has coves, islets, and shoreline stretches with no road access at all — spots most visitors to Squamish never see, because the only way in is by water. Here's a look at what a boat gets you access to that the highway doesn't.
Howe Sound is a fjord — steep, glacially carved terrain drops straight into deep water along much of its length, with the highway (the Sea to Sky) tracing only one side. [Confirm and name specific spots along your actual route that are genuinely inaccessible by road — islets, coves, waterfalls only visible from the water, old settlement sites, etc. Avoid naming a specific spot unless you can confirm it's accurate and appropriate to publicize.]
A lot of our guests have driven the Sea to Sky highway before, hiked the Chief, maybe done the Sea to Sky Gondola — and still haven't seen this side of Howe Sound, because it's simply not visible from land. A boat tour isn't competing with those experiences; it's showing you the part of the area that's structurally off-limits without one.
If you're visiting for a longer Sea to Sky trip, a jet boat tour works well alongside [confirm what you'd genuinely recommend pairing it with — Whistler, the Sea to Sky Gondola, Shannon Falls, Squamish's climbing/hiking scene — whatever you'd actually tell a guest]. Many guests book a tour as one piece of a longer Squamish or Whistler stay rather than a standalone trip.
Exact stops on any given tour depend on weather, tide, and time of year — [confirm whether your route is generally fixed, or adapts trip to trip], but the throughline is the same: you're seeing a side of Howe Sound that stays out of reach for anyone without a boat.
