If your travel taste skews more toward pampering than adventure, but the wildlife and wilderness of the Yukon beckon, this is the package for you. Luxury Yukon river safaris – given all the float planes, custom riverboats and remote  “luxury outpost camps” involved – don’t come cheap.  That’s why, with 50 percent off for the rest of the summer, now’s the time to go. We think it’s worth it at full price – Ilana Weitzman, enRoute’s editor-in-chief, travelled this glorious river for us last year – but now Horizon & Co. is offering their 8-day deluxe river adventure at half price.
