The summit features a parking lot and public restrooms for visitors intending to hike in the area.

A gate just east of the parking lot restricts access to Angeles Crest Highway between the saddle and Vincent Gap during the winter due to heavy snowfall.

A second gate just south of the saddle permanently restricts access to the northern portion of State Route 39.

Two of the trailheads are part of the Pacific Crest Trail which crosses Route 2 at the saddle.

[4][5] Islip Saddle can be reached from Mount Islip on the south side of the mountains, or by from the north side from Angeles Crest Highway or from Crystal Lake Recreation Area.
