From the exit on I-70 for Silverthorne, (#205) head south on US HWY 6 (aka: Blue River Parkway). The highway north of the interstate becomes State Highway 9, but south of the interstate it's US 6. Drive south and east along US 6 to Keystone, passing several arms or bays of Lake Dillon. As you come to the Keystone Ski area, watch for a right hand exit/turn onto Montezuma Road. This will be the last turn possible, before the highway begins the climb to A-Basin and Loveland Pass. It's between mile markers 216 and 217. If coming from Loveland Pass and /or A-Basin, you will have to go past this exit, turn around at the first possible opportunity (Godola Road for Keystone), then drive back east to the exit. Measure distances from the stop sign once you exit. The Montezuma road goes briefly south, passing by some of the parking for the ski area, then heads east and follows along the Snake River. At about 4.3 miles from the turn off from US 6, watch for the road to make a sharper left, then right turn. At that right hand turn, make a left turn onto FR 260. This is the Peru Creek Road. There is a large staging/parking area here. Coordinates for the turnoff are: N 39° 35' 31.28" W 105° 52' 15.66". Continue another .7 miles to the townsite of Montezuma and a Stop sign. Watch for the speed bumps.
From the center of town, continue south another 1.1 mile. Turn LEFT onto the Webster Pass Road. (This may also be identified at least on Google Earth as "Bullion Mine Road." Also, several internet sources have repeated the same error saying the turn off is to the right.) Coordinates for this intersection are: N 39° 34' 04.43" W 105° 51' 37.28". Going straight at this intersection will access the Deer Creek staging area and road. On the Webster Pass road, the first .7 mile takes you SE through forest with still several homes/cabins. Be careful not to take any turns into private drives or to double back direction at any point. You will see two possible turnoffs for the Bullion King Mine. Avoid these. At .7 mile, there will be a seasonal gate. You may find this closed and locked in the earlier part of the summer. Beyond the gate, the road gets rougher, soon passing through the bottom end of a large rock-talus area. Beyond there, the road continues in mostly open terrain past potholes, mudholes, etc. to a place where it crosses to the west side of the Snake River (now just a creek.) There is parking at a spot just before the creek crossing and possible at-large camping nearby as well. Attempts to drive beyond here will take you onto the more rugged 4WD section of the Webster Pass Road.
If not equipped with a higher clearance vehicle, then from the center of Montezuma, continue driving south for 1.5 mile to a road fork where the main road heads right to cross Deer Creek. There is a large parking area before the creek crossing. From here you can begin walking up to the Webster Pass Road which is uphill to the NE. A lesser road/trail leads up to make the connection. At all points, there is an abundance of private property all around Montezuma. Please respect postings and do not attempt to camp near those properties. Starting from this point will add 1.6 miles one-way or 3.2 miles RT to the overall hike and another 475 ft. in elevation gain if doing the Geneva-Santa Fe route.
Additional Note: Both Geneva and Santa Fe can be easily accessed and climbed from the Guanella Pass Road CR62 by turning off US285 at Grant. Head north and after 6.8 miles turn left onto FR119 for the Geneva Park CG. Continue past the campground up the same Geneva Creek Road 119, past the trailhead for Shelf Lake, and continue driving now in a more westerly direction into the basin east of Geneva and Santa Fe Peaks. Drive as far as comfortable in whatever vehicle you have. The two summits can be climbed as a circuit from here with several branching old mining roads to assist with uphill progress.

Weekend camping anywhere around Lake Dillon can be problematic. Too many Front Range visitors and too few campsites. In the general Dillon area, try this website for some help: http://www.townofdillon.com/visit/camping-info
There are some primitive campsites up along Peru Creek. There appears to be room for some primitive camping at our trailhead coordinates. There also appear to be several primitive sites located up the Deer Creek Road (still CR 5) after crossing Deer Creek and driving south up the road (if you can get up it). Please be aware of and respect all private property postings.
