Narrative:

National park service has imposed restrictions while flying in the gcn area. They have created several VFR corridors for aircraft transiting the area. A map has been added to the las sectional; however, it does not supply any navaids to locate these corridors. The restr areas and the VFR corridors should be depicted on the actual las sectional for navigation. Many small aircraft can't climb to 14000' to transit the area due to clouds, rain, non turbo engine, etc. I feel there are future accidents waiting to happen with all the tourist flts and small aircraft transiting the area. I personally took tracing paper and tracked the park service map, then transposed it on the las sectional using the gcn VOR. Then I could at least get close to the corridor using DME and VOR to establish a point to change course until I reached the river, then turn back and intercept the bryce canyon VOR. I also called prc FSS to see if VFR pilots could get vectors through the dragon corridor by lax flight center. They told me that was the first time anyone had requested that information and they did not now the answer. Please look into this situation. I feel we have a potential danger the way it is now.

Title: REPORTER DESIRES SECTIONAL CHART OVERLAY OF VFR CORRIDORS FOR THE GCN AREA SO THAT SMA CAN NAVIGATE BY REFERENCE TO VOR THROUGH THE CORRIDORS AND OR OBTAIN RADAR VECTORING FOR VFR FLTS THROUGH THE CORRIDORS.

Narrative: NATL PARK SVC HAS IMPOSED RESTRICTIONS WHILE FLYING IN THE GCN AREA. THEY HAVE CREATED SEVERAL VFR CORRIDORS FOR ACFT TRANSITING THE AREA. A MAP HAS BEEN ADDED TO THE LAS SECTIONAL; HOWEVER, IT DOES NOT SUPPLY ANY NAVAIDS TO LOCATE THESE CORRIDORS. THE RESTR AREAS AND THE VFR CORRIDORS SHOULD BE DEPICTED ON THE ACTUAL LAS SECTIONAL FOR NAV. MANY SMA CAN'T CLB TO 14000' TO TRANSIT THE AREA DUE TO CLOUDS, RAIN, NON TURBO ENG, ETC. I FEEL THERE ARE FUTURE ACCIDENTS WAITING TO HAPPEN WITH ALL THE TOURIST FLTS AND SMA TRANSITING THE AREA. I PERSONALLY TOOK TRACING PAPER AND TRACKED THE PARK SVC MAP, THEN TRANSPOSED IT ON THE LAS SECTIONAL USING THE GCN VOR. THEN I COULD AT LEAST GET CLOSE TO THE CORRIDOR USING DME AND VOR TO ESTABLISH A POINT TO CHANGE COURSE UNTIL I REACHED THE RIVER, THEN TURN BACK AND INTERCEPT THE BRYCE CANYON VOR. I ALSO CALLED PRC FSS TO SEE IF VFR PLTS COULD GET VECTORS THROUGH THE DRAGON CORRIDOR BY LAX FLT CENTER. THEY TOLD ME THAT WAS THE FIRST TIME ANYONE HAD REQUESTED THAT INFO AND THEY DID NOT NOW THE ANSWER. PLEASE LOOK INTO THIS SITUATION. I FEEL WE HAVE A POTENTIAL DANGER THE WAY IT IS NOW.
