This is an out and back to the beautiful 4-Mile Basin Mountain Lake. Bring a lunch and enjoy the view at the top, before coming back down. Feel like a little more riding? Ride over to Lower Twin Lakes to see another mountain lake before you come back out. The trail is fairly new and and non-technical until the last mile to the lake. This mile is a classic old trail that will challenge you.

Access Info

You can drive the old dirt road near the bottom of Spring Hill, up to the trailhead(a vehicle with good clearance is recommended). You can add a bit more to the ride by parking at the Spring Hill Picnic Area and riding the dirt road up to the trailhead. This doesn't take much more time for fit riders then driving in, but coming out is actually much faster on a bike then driving.

      		 reporter Still a few muddy and wet spots up high. You can ride it, but it's a bit messy. Might give it another week or two if you want to miss the mud.

       Today I rode to both the twin lakes and 4-Mile Basin Lakes (There is also an upper one). If I was to choose one over the other, I would recommend 4-Mile Basin, but that's just my personal preference. The climb is more consistent, the downhill is faster, the views are better and the lakes are higher and deeper (great for swimming if you like cold water!)
      As for the access road to the parking lot, it was fine for our little old subaru forester in dry conditions. The worst part of the road is the last half mile, and there are places to pull over/turn around if it gets too much for your vehicle.

       Both legs of this “Y” are worth doing. 4 Mile Basin is a little easier technically, but has some steeper climbs.
