hiking maps / Gp to sentinel dome via 4 mile

[ctfshjohn]

Do i need any maps ahead of time for taft point, sentinel dome, illouette and back from GP trailhead.
i cant see myself getting lost there but figured i would ask, and where to get them online if i need them.
also id like to to take the 4 mile down to the gate from GP,
can i continue onto sentinel dome from there and back to GP?
maybe i should just go to and from sentinel dome from the official trailhead off gp road.
are the views any better from one trail or the other?
thanks !!!!!!!!!!

The trail to Sentinel Dome and Taft Point at GP is clearly marked. I went as far as Sentinel and at the junction there was a sign for Taft Point. With a reasonable sense of direction I say you don't need any maps.
