Trillium Lake campground has the best location for Mt Hood views, hands down. The campground is quiet, not too many amenities(pit toilets, picnic table, fire pit). Camp sites are far enough apart for privacy which is always appreciated. We spent one night here, arriving early afternoon in hopes of snagging a first-come first-serve site- lucky us, they had a few available. They post the available sites on the information sign as you drive in. As we entered the campground we found the camp hosts and secured our spot for the night. One of the best parts of staying here is Trillium Lake itself- you can kayak, canoe, or stand-up paddle board on it. The views of Mt Hood reflected in the lake are stunning. I recommend doing the Trillium Lake Loop trail that goes around the entire lake(2 miles). At the time of our visit a section of the trail was closed but it wasn't well signed from the side we approached from, oops- something to watch out for in the near future.
