I greatly enjoyed a hike around the Enchantment Lakes in the Northern Cascades (Washington). The first day was an arduous 10-mile hike with about 5,000 feet elevation gain. I found a good place near one of the lakes to pitch my tent. The next day, I hiked up and around the entire basin, marveling at the changes in terrain and climate zone as I gained further elevation. There were also spectacular views over a very steep slope in one direction. I met only two other people that entire day -- two young men who were camping near one of the lakes and concentrating on catching fish for their dinner. The next day, I hiked back down to the trailhead.

That was a fantastic hike. My day of hiking around the Enchantment Lakes is still a vivid memory today, 36 years later! I understand that the Enchantments have attracted a lot of people since 1972 and that backpackers must now obtain permits in advance, etc. I'm sure they're still worth the effort...
