Reviews for Fossil Bay Mooring Field and Dock
Dock depths June 2017, 2017-06-24
Captain: , Hailey, Idaho (50)

Spent 3 nights here on some big minus tides. Western most of the two docks has 6 feet of water at the outer end of it at a zero tide... with 5'2" draft we stayed for a -1.1 tide without touching bottom... probing with boat hook bottom seemed soft but no guarantees. Northeastern dock has ~5' at zero tide in the middle of it (on northern side) with about same on way in and out but double check.

Early spring update, 2016-03-31
Captain: , Willamette (31)

We visited for the first on March 19, 2016. It was very nice but I was hoping to find a dock tie early in the season. It seems that they may remove one of the docks. So there was only one dock when we visited and had to grab a mooring buoy. Also the water was not yet turned on. We had a nice hike around the island and enjoyed it. Will likely stop again in the future just o idea when.

Great place to stay., 2015-05-07
Captain: , Anacortes (147)

We where here on the weekend of may 2-3 with our yacht club. we were rafted on the outside of the inner most (west) dock. about mid dock rafted three out. I am posting this to report depth at low tide. at a one foot low we had 7 feet under us.

Great Place anytime of the year, 2015-04-17
Captain: , Kirkland, WA (4478)

At the dock or on one of the moorings this is an excellent place anytime of the year. All of the moorings have recently been replaced with new. Very popular in summer months but only only a few boats in the off season.

Great anchorage, 2014-09-09
Captain: , Olalla WA (412)

We've stayed here many times, at the dock, on a mooring ball, and anchored. All are lovely. Fills up every evening. We stayed here 9-4-2014. Wind blows across the spit of land from the north, or from the south, but holding is excellent. Great facilities and hiking. Definitely pay attention to tide tables near Full or New Moon, as dock and mooring balls are in very shallow water at low tide. We were ok with 4-foot draft, but larger boats left the dock early in the morning as they were almost sitting in mud.

A real jewel of a state park, 2013-09-15
Captain: , Swantown Marina, Olympia, Wa (180)

8-20-2013 Stopped here for a couple of days and decided to stay longer. This park stands out over the other Washington State marine parks I have visited. All facilities well maintained. Park staff is visible and stay on the move. Fossil Bay has boats arriving and leaving all day long but fills up by sundown each evening. I lucked out by getting the first mooring bouy as you enter the bay on the right. The deeper moorings are as you enter Fossil Bay. I draw 6 feet and on a low tide I only had a couple of feet below my keel.
I would suggest paying close attention to tide tables in this area and refer to charted depths before mooring here if you have a deep draft. Echo Bay may be a better choice!

Wonderful place, 2013-09-04
Captain: , Calgary (84)

We stayed here for 4 nights with a club rafted up at anchor. The holding is great. Watch the tides as the depths can get shallow at the end of the bay. The facilities are clean. The island itself is scenic and well worth a hike

Secure and Cozy Anchorage, 2013-07-20
Captain: , Bellingham, Washington (192)

We tucked in here and picked up a mooring during a S blow and found it quiet and calm. Although the wind was blowing into the entrance, waves were not makling it very far into the anchorage. Wind switched to SW during the night and we were calm and cozy. This was early July and there were still a couple of empty mooring buoys come morning. Might fill up faster in nicer weather, I expect. Easy dinghy ride to the dock which has reserved space for dinghys. Plenty of hiking trails on the island for some much needed exercize. Definitely will be back here often as Sucia is a very convenient stop on the way down from Blaine.

Great location- got lucky and grabbed a bouy midday in August!, 2013-03-31
Captain: , Novelty, WA (214)

Great little spot- spent a few hours on the bouy during the day- didn't stay overnight. Area was patrolled by appropriate Sheriff via boat. Quiet, definitely busy spot in August. Seemed fairly well protected unless the wind is strange and coming from the SE. Constant stream of vessels coming in and looking for a spot to anchor or grab a bouy. Worth it though, and not so busy that you seemed like folks were on top of you.

Missing mooring bouys., 2012-09-12
Captain: , Salmon Bay, Seattle (33)

Just after Labor Day, 2011 we pulled into Fossil Bay for the first time and grabbed one of the full field of 14 mooring bouys. A medium blow overnight resulted in being woken up by a park ranger yelling from his boat. Still attached to the bouy, we had drifted across the bay, through the other line of boats, and were about 10' from grounding our screws. My thanks to the ranger, and we were lucky, but not a fun thing to deal with before the morning coffee.

So this year, just before Labor day this time, we found that there were only 5, maybe 6, of the original 14 bouys remaining. A ranger told us that boats have been running over the pendants at low tide (not sure that makes sense) and that they haven't had the resources to repair or replace them.

This is a wonderful bay, but heavily used, and the mooring bouys are useful for boat density in the relatively narrow area. I hope the bouys get replaced(?).

Wow! Great Spot!, 2012-06-21
Captain: , Saint Louis (50)

Beautiful spot - a must visit in the San Juans! We were there in June when it was peaceful - only three other boats in the cove.

Be sure and pay your tab on the shore for a mooring ball - the Sheriffs came by checking.

So wonderful, 2012-06-13
Captain: , Seattle, WA (437)

We came for a day visit during the week in mid-June. Plenty of space at the inner dock

New fees for 2012, 2012-05-28

Great place for short hikes, 2011-05-24
Captain: , Port Orchard WA (133)

While staying here you can follow nice trails that are pretty easy. Nice views from the top

Fossil Bay -- Long and Narrow, 2011-01-26
Captain: , Anacortes, WA (282)

Fossel Bay is a long, narrow inlet running from the SE to NW at Sucia Island. Near the head of the inlet there is a State dock. Extensive mooring bouys and a "mooring structure" -- a mooring line with floats running between anchor points-- provides good secure moorage.
The dock leads to stairs and a fee box.
This is a wonderful overnight spot or extended stay.

Fossil Bay, 2009-05-20
Captain: , Blakely Island, WA (372)

Lot's of mooring balls, two docks. The most popular place to stay on Sucia, can be very crowded during summer.

Fossil Bay Dock, 2007-11-30

The #1 spot in the San Juans!
