Our guide, Mitch, was incredibly professional and kind (he contacted me again via email and text message the day before departure to confirm our trip). Of course, I had many worries beforehand, but I'm so glad the journey went smoothly! If you like the gloomy rainforests described in Twilight, you absolutely must see this! The scenery in Olympic National Park is spectacular (although some of the mountain paths are a bit steep). I really enjoyed this trip! The scenery was truly beautiful and vast, and I was lucky enough to see deer at the end!
