Sorry Jayeltee, didn't see your question up until today. Hopefully you did manage to get to the trail head of Mt Slesse. If not yet, you don't really need 4X4 but you do need high clearance vehicle! Good luck!
Hello goaroundglobe, I am hoping to hike the Mt. Slesse Memorial tail on Labour day. Is the road to the trailhead accessible by a regular car or is a 4x4 or lifted vehicle needed? Your help is appreciated! :) Thanks Jayeltee
