First, I suggest you get the Swan Lake Ranger District map. **This is not in the Glacier Cyclery Ride Guide** Continue up the road, now on your bike, toward the Jewel Basin. Reach the Jewel basin parking lot. Now, you are going to take trail #717 toward the Jewel basin, which takes off from the parking lot directly across from the road you rode up. You may see signs that say "no bikes allowed," but whip out your Swan Lake Ranger district map: trail #717 actually is fair game for bikes, and it leads RIGHT UP to the Jewel basin... it is illegal to ride in the Jewel. But i repeat, #717 goes right up to it... and you won't be going in it. So follow #717 until you get to a massive junction with trails going everywhere (up to Aeneas, to some lakes...) now, you can't continue going straight without being illegal. But, the trail you are looking for is Switchback trail #725, and it turns around and heads down the frontside of the mountains, away from the Jewel basin. This is the trail you are here to ride. When you approach the big intersection on #717, #725 is a sharp right, 180 degree turn. Again, do not go into the Jewel. Now, descend about 42 switchbacks over the course of 3 miles to your car.
