<map lat='36.114581' lng='-115.169678' zoom='10' view='3' float='right' /> Las Vegas is a city in Nevada. The legality of hitchhiking is tricky, make sure to not stand "in a roadway" "exclusive of the berm or shoulder." Standing on the shoulder or sidewalk of a roadway and sticking out your thumb should be fine, still it's probably better to not be hitchhiking too openly when you see police in the distance (or nearer by). The interstate (highway) has a different jurisdiction, you might not want to walk too far up the on ramp.
Note: there is a fairly frequent SDX bus that can help you get away from the Strip.
North towards Beatty, Death Valley, Carson City, Reno
You can take the 106 bus (slow) or the Centennial Express (CX) bus (faster) towards Centennial Heights. There's an on-ramp not too far from the terminal. guaka waited a relatively short while, to be taken to the next on-ramp, with much less action, made the mistake of going back, not getting any ride at all, and finally decided to walk all the way beyond the freeway part. There still, no one was picking him up for a long time. Around sunset a guy finally stopped on the freeway. Verdict: leave early, take anything going north, and be prepared to walk a lot. No problem with police though, even walking on 95, at least beyond the point where the road ceases to be a full on highway.
US 95 looks like a logical route to Reno, Nv. but almost no one travels this way. Very few services or people. After hitching, 5 continents, I can say this is the worst in the world. Intense police interaction, enthusiastic enforcement of anti hitching law, even in incredibly remote areas. Best advice, bus to on-ramp for 95, take no short rides within the city limits (very heavy police interest +city sprawls out for more than 12 miles. After that you may be forced to solicit rides at gasoline stations. Consider shifting route to go out I-15, This is horrible...paranoid large RVs, over full vacationers, and very very little traffic beyond the city limits. I say this after hitching Montenegro, Panama, and Turkey just this year.
North on I-15 towards Salt Lake City, Utah
The most northern part of the city right before you leave there is a rest stop/truck stop at exit 54 for the Las Vegas Speedway. This is an excellent place to go north. This is the last chance for people leaving Las Vegas to stock up and there is really only one direction for them to travel and that is north on I-15. You will likely be picked up by a truck driver.
South/East towards Interstate 40 (Flagstaff) or Phoenix
In Las Vegas there's a bus that goes all along Tropicana Ave (stops at the Strip too!) that can drop you very close to the on ramp of 68. The stop is somewhat after Sandhill Road. Just communicate with the driver, he will know. A ticket is 2 Dollars. From the on ramp it's pretty easy to catch a ride. Just make sure you bring enough water cause it gets really hot out there and you might wait for quite some time...
It is easy to catch a ride to Boulder City, once there, getting out can be slightly tricky. Keep walking out of town along US 93 until you pass the last big intersection (Nevada Hwy). The shoulders are wide, but traffic is going fast here; you may catch slower traffic merging from the intersection. It may be wise to use an extra large hitchhiking sign here for the swift traffic to be able to read. Unfortunately there is no better place to catch a ride than this. At least you will be visible to any and all traffic leaving Vegas in this direction.
South towards Los Angeles
On West Tropicana Ave about a 15 minutes walk from the Strip (0.8 Miles) there's a truck stop around Wild Wild West Truck Plaza. Lot's of Trucks are leaving to Los Angeles from here. Just hang out here for a while and talk to the drivers...
