Agate Pass is a 1 mile, high speed drift dive from the SE corner of the Agate Pass Bridge to a park called Old Man House State Park. It is a relatively shallow dive (35-40ft) that affords you the unique opportunity to soar over the bottom covered with carpets of anemones, do effortless flips and cartwheels and play in the eddies behind rocks. It is a unique experience to succumb to the pull of the current and ride it along to your exit point.
Upon entering the water under the bridge, descend and steer toward the middle of the Channel (35-40fsw) and enjoy the ride. The time you are under the water will depend on the speed of current.
The only real trick to diving this site is knowing when to ascend. Come up too soon and you’ll have a long walk ahead of you, too late and you’ll have a heck of a time getting back to the beach. Stay in the middle as long as you can until you feel it is time begin your exit. If you move too far left too soon (NW Shore) you’ll hit a back eddy that will impede your progress down the channel and you’ll end up walking to the park, but it also works as a nice “safety net” if you feel the need to end the dive. On a one knot current you can plan to drift for about 25-30 minutes before you need to turn toward shore and begin your swim to the exit point. Good luck, it’s tricky!
This site description was written for an EBB TIDE only (out going tide). I do not know if it can be done on a FLOOD.
This is truly an advanced dive for divers in good health. Keep an eye in front of you so you don’t get dashed against a boulder. Plan a lost buddy procedure because it is easy to get separated in extreme current. Depending upon your luck and skill (or lack there of) you may be in for quite a walk or swim to find your exit point. Make sure you are physically prepared to do so. It is not a bad idea to have a non dive on shore at Old Man State Park with a bright flashlight to signal you to your exit point (in case of fog) and to drop you off at the entry point. Be ware of boat traffic overhead.
How to get there:
NOTE: This will require two vehicles or one person who does not plan to dive who can drop the divers off at the entry point and pick them up at the park.
