I drove to the trailhead and it's private property now.
We did the whole Duna Vista loop. took us about 5 hours with short breaks here and there. seems longer than 7 miles on foot. We started from the the end of high mountain rd in lopez. Great way to burn some calories for the day.
Great ride with Steep sections towards the top. The ride is singletrack the whole way with wonderful views. Make due to check out the net spur off the top after/before checking out the Duna Vista.
Nice trails. You have to pay to get into Lopez lake. Was told there was another way to access the trails on the backside but wasn't sure what road to take. Lots of spurs and trails that connect so pay attention to the signs.
Took a partial hike of the Dune Vista loop. The weather was wonderful and trail was quiet and empty except for the two deer we came across. Great day and a great trail.
From Lopez Lake, drive on Hi-Mountain Road until you turn left of Upper Lopez Road. Take this road until you get to the Boy Scout Camp on the left side of the road and walk through this property, following the Duna Vista signs. It's a rolling hike with some good steep areas. Mountain bikers also use this road and come flying down some of the hills. The top of Duna Vista will give a bench to sit on while viewing Lopez Lake, the dunes at Oceano and the Pacific Ocean. Beautiful. Great workout for sure. Bring lots of water, especially on a warm day.
