Reviews for Warren Island State Park
Moorings are now $20, 2016-08-23
Captain: , Newport RI (490)

The moorings are posted on the pickups and there is a sign on the dock to put your money in the iron ranger. We enjoyed the short hike around Warren Island. It has some spectacular waterfront campsites. Easy dingy ride to Islesboro.

Beautifully Maintained State Park, 2015-06-29
Captain: , Freeport, ME (608)

I couldn't give 5 stars only because, being a park, there are no shopping facilities. However, there are free moorings, ranging in weight from about 500# to at lest a ton, maybe more. The cove is well sheltered fro all directions except the North, and partially from that direction.

The island does charge admission, same as most all state parks, but $1.50 a day for seniors is pretty reasonable. Park manager is Byron, who takes great pride in how the island is kept up.

On the island you'll find campgrounds with fire sites, outhouses, walking trails, and picnic areas. Some views of Penobscot Bay are great.

2000 lb mooring, 2014-09-06
Captain: , Beverly, MA (1242)

I got there early and was able to secure one of the 2K lb moorings, great hold and felt real secure with a little blow that evening.

Bring bug spray, 2014-08-12
Captain: , Longmeadow, MA (70)

We picked up one of the park moorings. It turned out to be one of the lighter (150 lb mushroom) buoys. It still held our 40-foot sailboat in 10 knot winds without issue. The island is beautiful, but if you go ashore bring bug spray. The misquitos were swarming all evening and into the morning. There are a couple of outhouses on the island that you can use, but beware: They are just holes in a shack - very primative. The only drawback to the area, aside from the bugs, is that the Isleboro Ferry parks just across the bay and leaves their lights on all night, so it disrupst "stargazing". But overall it was a great spot.

Could not get anchor to set!, 2013-08-08
Captain: , New Castle, NH PGI, Florida (320)

All but one of the moorings were taken when we arrived on a Thursday late afternoon; the open mooring was the furthest in, someone told us it was big enough for our 35' sloop, but our depth at half tide was only 4.5 feet in some places (we were swinging in the wind). So we cast off and tried to anchor in four different spots just outside the mooring field, and could not get the anchor to set. It looks like a lovely anchorage, but you better get there early to get a mooring!!

Busy, but Sheltered, 2011-09-21
Captain: , Deer Isle, Maine (514)

Took one of the moorings here one night in September. There were lots of other boats at the moorings, but most left before night. Explored the hiking trails around the island. The place was well-manicured. The area was fairly busy with the ferry coming and going and a generator running on another boat, but it quieted down at night.

Mooring and a state park, 2011-07-23
Captain: , York, ME (1971)

This is a great spot, the whole island is a state park complete with campsites, trails, picnic areas, outhouses and drinking water. You can land a dingy at the dock or on the beach next to it. There was a lot of activity when we were there; campers coming and going, and a windjammer cruise had a shoreside lobster feast in the picnic area. It all quieted down at night.

The moorings are mixed, some 1-ton+ blocks and some 150lb mushrooms. The floats are marked. One of the mushrooms held us OK (a light 30-footer) in a 15-knot wind with higher gusts. But the problem with mushrooms is they only hold if they're set deep in the mud. If someone too heavy drags one, it'll take a while to re-set. They really should just use all granite blocks. Meanwhile, choose carefully. The park rangers ask that you sign in on the island, and make a donation for the mooring. We did, this is a place worth supporting.

Nice hike ashore, 2010-08-23
Captain: , Ft. Myers, FL (134)

Moorings here vary in size with only a few larger than 150lb granite %u2013 satisfactory for our 15 tons on a calm night, but we were told a 40%u2019 trawler had dragged the same size mooring and left. A small donation for moorings and trails is on the honor system at the state park ashore.

One of the best kept secrets around, 2009-06-09
Captain: , Fredericton, NB, CAN (477)

We love it. With its ten free state park moorings, all labled by weight. Protected and peaceful.

Take your dingy to shore and walk around the island. Also take your mosquito repellant. There is a ranger station (sort of) with friendly people. There is an exchange shed with lots of stuff. Campers are encouraged to leave anything they did not use for others.

If I were ship wrecked here - I could live for weeks on the provisions in the exchange shed!

A great spot, close to Camden and Belfast.

No ammenities, but a beautiful state park.

A park for boaters, 2007-08-21
Captain: , Milford CT (658)

Warren Island is well kept with nice walking trails many camp sites and out houses. Free moorings a dinghy dock. great protection. Shale beach on the south end. The water there is warmer.

Moorings, 2007-02-11
Captain: , Georgetown, Maine (144)

Moorings are free! Explore the island - a state park for a small fee

A nice place to visit, 2007-01-29
Captain: , MV Red Head (61833)

We've gone to Warren Island many times and used the free state moorings. The island is a state park and is a nice place to walk around. The anchorage area is well protected. I'd be a little careful with a large boat on the moorings. They are made for smaller boats. Gilkey Harbor is a beautiful place and Islesboro is worth a visit.
