Trillium Lake is a classic spot and if you have never been, it is always worth at least one visit. Picturesque views of Mt. Hood over the lake, often with pristine reflections, make this spot an iconic bucket list worthy destination. Campgrounds are decent, what you’d expect in the area. The lake is great for swimming in the summer, and the area is fantastic to snowshoe in the winter (be advised the gate to the road closes in the winter and you will be trekking through snow). All in all, a lovely place, especially if you like to take photos. It can get insanely crowded during the summer months especially on weekends, so be prepared for that. The area also sees litter from said crowds, which is disappointing. Please leave no trace :)
