Campgrounds in Washington
Washington State is big enough and its terrain varied enough that no matter what kind of outdoor activities you enjoy, Washington has got you covered. There are the coastline on the Pacific Ocean, the mountains of the Cascades - including a few volcanoes, the rainforest of the Olympics, the thick pine forests of the west and the dry deserts of the east. There really is something for everyone.
One of Washington's most popular camping areas isn't in the thickly forested parts of the western part of the state, where the highest population concentration is, but rather in the upper northest corner of the state around Spokane and Wenatchee. This is desert camping at its finest, partly because it's not all bone-dry and stiflingly hot - there are some forests and lakes around to vary the landscape and the outdoor activities you can enjoy.
The glorious Cascade Mountains are another popular Washington camping destination, and the good news is that there is plenty of room for everyone who visits. The eastern side of the North Cascades is a bit harder to reach, making it a great option for those who really want to get away from it all, but there are plenty of campgrounds up and down the mountain range.
If you'd like to be a little closer to civilization, you could try the Puget Sound area, some parts of which aren't far from Seattle. The largest National Park in Washington is the Olympic National Park, which is another great camping choice - just remember it's not called a "rainforest" for nothing. Bring your wet weather gear along or you might be incredibly unhappy.
Washington doesn't have many National Parks, but there are a couple big ones. Here are a few of them:
There are also plenty of Washington State Parks which also make great camping getaways. You can find out more about them here.
