Here in Las Vegas we (our trail committe) have been working for well over a year on a project called the Vegas Valley Rim Trail (VVRT). When finished it will cover over 110 miles and be a trail system, i.e it will join parts of several other trails as sections of the VVRT.
We have been extremely fortunate that the Outside Las Vegas Foundation has been able to sponsor us ever since Clark County ran out of funding early on when the Great Recession hit us hard. So far our professionals at Outside Las Vegas and some of the committee members have raised over $40,000. for preliminary work and research on economic benefits to the community. This is needed to be able to present a realistic "ask" to future deep pockets donors who we need to come up with donations from $250,000, to $1 million or more. The entire project may run to $10 million. when completed with signage, bridges, parking trailheads and rest benches/shelters. (Remember, this is 'Vegas, where it gets HOT.)
We expect to see the tread alignment surveying begin around 2014 or maybe even earlier, depending on grants and right-of-way negotiations with the BLM, County government and the three cities in the valley.
Yes, the VVRT is an urban system that is ALSO a non-urban trail in certain sections.
Camping will be permitted off-trail in certain areas but water sources are scarce here in the Mojave Desert so it's mostly "bring-your-own-water".
This a going to be a long process and may not see the last section completed until 2018 or even 2020 but by the end of this summer about 1/3 of the loop will be finished in terms of municipal trail building, not VVRT made trails. The City of Henderson (southern 'Vegas city) has done the lion's share of trail building so far. The BLM is in the process of building 44 miles of trails south of the valley but they will not be part of the VVRT, just linking to it. The point is that the VVRT will link MANY miles of other trails for hiking and/or backpacking, equestrian use and mountain biking. NO motorized vehicles permitted, natch.
The umbrella organization that weighs in on this is called "Neon-to-Nature". A fitting name given 'Vegas' reputation for The Strip. When finished the Las Vegas metro area can boast of a trail that runs from Red Rocks NCA in the west to the River Mountains Loop trail in the east, linking people to other great trails and spectacular scenery that surrounds us. Can you say "ecotourism"?
Wish us luck in our oddessy.
