Seacrest Park Cove 2

#1 - Seacrest Park Cove 2

USA, Washington

This is the 2nd most dived site in Washington for good reason. Easy and lots of fish, invertebrates, and giant pacific octopus. Ropes mark popular dive routes. Several sunk boats and other artificial rubble on the mud bottom add additional area for life to grow. Huge sunken pilings to the right of access are covered in massive plumose anemones are an impressive sight and attract a variety of fish. Octos are also a common sight here once you learn where to look. Free street parking or in ferry/restaurant parking lot. Easy gravel beach for shore access. There are steps on both ends to get to beach. Parking fills up on weekends by non-divers and divers alike (this is the 2nd most used dive site in the state). If you don't want to have to walk go early and get a great spot mere feet from where you splash. Seacrest Park Cove 2 is also known as Alki Cove 2.

Incredible dive site, Great for macro photography and also a great night dive. need to be respectful of local nieghbors. Three distinct dive profiles here. 1.)Straight out, down the tire piles. 2.)To the left of the entry is a cabin cruiser in aprox 60 fsw 3.)to the right, out to the junk yard. Do this dive with someone who knows the site. Most of the time there is a slight eddy current going from the north to the soth towards the point. Current will increase as you get closer to the point. Limmited parking space. About 5 car's max Maybe 6. No utilities/Restrooms or fresh water. Three Tree N. is also known as TTN.

Just South of downtown Seattle, take the West Seattle Bridge to hop over to West Seattle. Just before the bridge ends, make a right onto Harbor Ave SW. Drive Northwest until you round the point and find yourself heading Southwest on Alki Ave SW. The whole stretch is considered Alki Beach Park, but drive to the end of the beach section before parking. Just before the beach residences, there will be a pathway down to the beach.
Saltwater State Park

Underwater artificial reef for scuba divers. Because this is a marine preserve the number and size of fish are impressive for a shore dive. The underwater rocks and metal poles have grown an excellent amount of life over the years so it is worth the surface swim out. The two white marker buoys mark the first and last of the 3 artificial rock piles. Saltwater creek is a state park so typical state park restrictions apply: open dawn-dusk and discover pass required for parking. If you get a space up front you will be parked extremely close to the beach. There is a dive map posted on site which will show the three artificial reef rock piles and the location of the white marker bouys you can use to find them.

Easy shore dive and great option when cove 2 is super busy. Pro tip: Are you fine with a short walk? Start at Cove 2 and swim south along the shore past the underwater pilings. Keep going underwater all the way to explore cove 1. You essentially will have explored a good portion of TWO different sites. You can walk back on the park trail (depending on which cove you parked at). Free street parking along park and super easy shore entry Seacrest Park Cove 1 is also known as Alki Cove 1.

Public restroom and shower at edge of beach. Keep clear of the fishing dock and ferry as they are no-dive zones. Free street parking. Very easy entry from beach north of the restaurant / ferry terminal.
