I spend a lot of time riding on the Western Beltway Trail whether it's this section or the section that continues south to Tropicana.
The trail gives you freedom to ride with greater security than on the streets. You still have to cross Hughes Park Drive, Sahara, and Charleston but when I ride on Sundays, these streets are generally quiet.
The trail north also is one of the best viewing areas for the annual July 4th fireworks at Red Rock Casino. I ride over about 8:45 and then watch the show at 9. The path is great for that. Note: Metro allows cars to jump the curb and park here for the fireworks so ride or walk there with care.
There is an odd curve to the trail at Hughes Park Drive. The trail ends on he south side and you have to cross HP Drive and then head west on Hughes Park. Then the trail starts again and does a little loop back until you're at the top of the small hill. You're then on level ground and can ride to Charleston.
The trail north will soon be longer. The city is extending the trail from Charleston Boulevard to Alexander Road using Southern Nevada Public Lands Management Act funds. This past weekend, Far Hills Avenue was closed for them to install the new bridge which will allow pedestrians and riders to go over Far Hills without stopping. The path will go under Alta Drive. Tentative completion date for the extension is May 1, 2014. When the extension is done, there will be a 10 mile one way ride from Trop to Alexander. What a ride it will be coming back up the hill from Alexander to the Summerlin parkway.
The trail is great! Give it a try.
