Beautiful views and great swimming lakes! We hiked it clockwise spending the first night at Wasco lake and the second night at Square lake. Overall a great hike but be prepared for HOT sandy trails that will burn dog's feet on hot days (it was 95 degF). Bring gators for sand. 90% of this hike is in the burn/full sun, only 10% of this hike is in the shade. Plenty of mosquitoes on the PCT between Santiam pass and Wasco lake. There's not much water between Santiam pass and Koko lake so bring a lot of water or fill up when you can. Wasco lake was crowded with hikers and mosquitoes. Square lake was awesome with no people and few mosquitoes! I'd recommend this hike, especially on days cooler than 90 degF and after mosquito season is over!
