Dive Site Information

Access: Access is via the boat ramp. Walk-in from the ramp on an easy gradient but can be slippery. The alternative/lower parking lot near the ramp puts you closer to the entry point.

Dive Profile: Shallow cove to the right of the boat ramp (when facing the water). Max depth around 50 ft. Points of interest at 15–30 ft, including a small wall at approximately 30 ft.

Bottom Composition: Sands

Hazards: Entry shares the boat ramp with boats. Once underwater, the site is too shallow for vessel traffic to be an issue. Main parking lot is a longer walk; the alternative/lower lot cuts it down

Current: Typically no.

Things to see: Gobies everywhere. Sailfin sculpin and grunt sculpin for treats. Plainfin Midshipmen throughout the shallows. Some rockfish as well.

Triton Cove makes a solid backup if Sund Rock or Octopus Hole are full. It’s a different experience — shallower, more macro-focused — but the drive is short and the site holds up on its own.

Frequently Asked Questions

Is Triton Cove good for beginner divers?

Yes. Triton Cove is one of the most beginner-friendly sites in Hood Canal. Max depth is around 50 ft, there’s typically no current, and the boat ramp gives you a gradual, easy entry.

Where do you park at Triton Cove?

Two options. The main upper lot has more space but is a long walk to the water with gear, including negotiating with stairs. The alternative/lower lot near the boat ramp is closer but smaller, and you’ll compete with boat trailers for spots. Do not park in the ADA space unless you have a valid permit.

Can I dive Triton Cove if Sund Rock or Octopus Hole are full?

Yes, and it’s a reasonable backup. Triton Cove is about 20 minutes north of Sund Rock and it is typically quiet. The experience is different — shallower, more macro-focused — but the logistics are easy and the marine life is worth the trip on its own.

What marine life can I expect at Triton Cove?

Gobies are everywhere. Sailfin sculpin and grunt sculpin show up regularly. Plainfin Midshipmen are common in the shallows. Some rockfish scattered around. On a good visibility day, the shallow cove has an aquarium-like quality to it.
