January 29, 2024, Skeeboggen Trail Ascent

This is a steady climb with a few steeper sections toward the beginning (bottom) just after the trailhead takes off from the archery range road. This trail winds through aspen groves up high and the trial has seen a lot of work and improvement recently. This one would also be a lot of fun to descend. This trail connects the lower parking lot for Sage Brush Flats up to the Blacktail Loop.

Hundreds of feet over the canyon below, you'll hoot and holler while you're riding across the safe old railroad trestle and onward to the tunnels!

Lava Mountain Trail is technical enough to challenge most riders. It's also part of the Great Divide Mountain Bike Route so theoretically you could keep riding up to Alberta, Canada or down to the Mexican border.
