Mukilteo T-dock is a great local dive site featuring many wolf eels, giant pacific octopus, crabs and fish. The largest feature is the 30' tall Geodome sitting in 50 feet of water, which was added as a tribute to a local diver. Many smaller structures have also been added that attract a large population of local creatures. The deepest features are at 125' and the shallowest features are around 20'. The site is easily accessible from the parking lot next to the Silver Cloud Inn. The entry is a concrete staircase down to a sandy/rocky beach. As of 2023, boats are the biggest hazard at the site, but there is a proposal to make it an official dive park, which would prohibit boat traffic. Currents can also be a hazard.
