Stay on the main road up the hill and past the spurs. The road descends and levels out through a wide, rock-walled canyon. Right heads up to Gemini Bridges. Get Adobe Acrobat. This point delivers vistas of the La Sal Mountains ahead and the twisted terrain of Bull Canyon and Day Canyon behind.
Cairns also assist in navigation.
If continuing to The Portal Trail, follow the cairns. This requires keen, attentive eyes. The trail loses a lot of altitude, then heads up and down as it romps along the rim. Don't miss this critical left turn out of the wash. Some people keep riding right on down the wash.
