Paul...welcome to the forum. I've been told that the Steven's pass to Snoqualmie pass is the most scenic stretch in the whole trail, but it's only 70 some miles. Still, I'd include it in any hike in the state of washington. I'm 68 and personally plan on 10 mile days. Also in June any hikers will be crossing still melting snow banks and downed trees. It all combines to slow a person down, at least it does me. If you're up to it, continue on White pass for a total of 225 miles. ( 14 days @ 16 mile perday-based on two weeks) a full day of arranging transportation needs and food gathering.
