My next spot is Reed Island State Park.

This spot is about 2-3 miles from our home port. The north side of the island is the first place we stayed the night on the boat. My wife wasn't confident, but it's a protected spot with little current. I knew that if everything went wrong, I could swim to shore and walk the trail home. Luckily, we didn't have any problems.
The water is deep enough to sail to the west and south of the island. East of the island has sand bars that move around. So watch your depth. We have an

so too often its the keel bumping off the sand and swinging up that's our alarm.
When the water is up in the spring, you can circumnavigate the island, but in the summer you can enter the north side from the west. The sand is always moving, but my experience is that it's deeper closer to the island. There are often large cabin cruisers tucked in here, but our Macs can tuck way farther up in the shallows. There's even a little sandy beach that I found when we had little neighbor kids on board and it was super windy out on the river.
The beaches on the south side of the island are mostly ankle deep mud with a lot of logs. It's not protected from wakes. The logs are fun to climb on and you can take a spa-like mud bath.
The southeast corner of the island is shallow in the summer for a few hundred yards off the shore. This is another fun spot to stop and play frisby or football in the knee to waist deep water. The beach here is sandy with more of those logs to cimb on.
The east end of the island is the spot for camping on a beach. In the summer, there are usually boats here. Most just stay for the day. So you can usually sail around until sunset and then slip in for the night. The tree block the sunset on this end of the island, so people usually leave relatively early. This is a sandy beach, but when the water is low there are muddy spots.
From this camping spot you look east into the Columbia River Gorge and the sun rises right over the river between the mountains on both sides. I can't seem to find a picture of this, but Crown Point is just south of here. Check it out to get the idea.
