I use it to make a loop out of Lost Lake. Usually by riding Lost Lake from Primrose to Seward, then back on the highway for 7 miles to the old ski area where the Meridian Lakes trail starts. I've run it both directions, starting at both trailheads. I like the one I described above the best. The other way I like doing Lost is out and back trailhead to trailhead. I don't like doing it just one way and a shuttle or whatever, it's fun, but too short IMO. The funny thing is, the mileage is almost exactly the same doing Lost out and back vs. doing it one way and coming back on the road and Meridian Lakes. 28.5 miles for both. Mainly, it's about doing something "more" than just Lost Lake one way. The fact that the rain forest is a totally different ride and experience is what makes it worth it IMO. Get to ride a little bit of loam that isn't typical of most of our trails. Riding the road portion kinda sucks...but 7 miles goes pretty fast IME. Was nice this year without as much traffic.So, do you park at Primrose, ride the road to Meridian Lakes, then ride up Primrose for the loop?
