Guide to Hiking Lakes in California

lakes Southern California

This is California – the beautiful, where millions flock on vacation. California is crowded: the population & tourists are only increasing each year. Thousands of people are looking for hiking mountains or better, a hiking lake – each weekend. Many are using the web for destinations, like the research you are doing right now. All folks seeking nature, water, cooler temps, fresh air & views. High Sierra, NorCal, SoCal Reservoirs, we list the best of these hiking lakes below.

Some of the lakes have mountaineering routes nearby; equestrian trails, regular hiking trails, campgrounds, some even have sorta level paved (granny) trails for biking, hiking & skating around.

High elevation or alpine lakes can be accessed best in summer months. Mountain bike, backpack, horseback into these hidden treasures. With any Sierra Nevada destination, snow pack deep can be in certain seasons. Major Highways (Sierra Passes) can be closed into June or July, due to rock slides and late snow melt. Snow shoes, snowmobile or 4×4 vehicles may be needed to reach such lakes, any months OCT-MAY (fall to spring). Winter can come early & stay late at these higher elevations of California; Be prepared for true Wilderness experience.

But maybe you are just looking for some easy hiking, loop trails & picnic spots; Or perhaps an overnight stay near a lakeside camp w/ kayak rentals. California reservoirs to alpine lakes, we have a wide variety listed below.

This page contains links to some favorite lakes with hiking trails around the lake, along the shoreline or routes on ridge lines overlooking the lake. If no good lake page could be found, we’ve linked to some photos of the lake on Flickr.

Toiyabe National Forest
Bridgeport Ranger District

If you are thinking about fishing or camping the Eastern Sierra, North of Bishop & you are not up for the crowds at Mammoth or June Lakes, then try the Bridgeport area, north on Hwy 395. Rural ranch lands along main road, Bodie ghost town turn off across the highway and Virginia Creek Settlement are also nearby

Green Creek is a 11 mile long dirt road in the lush Eastern Sierra the northern portion. The wide, graded dirt road is signed and dead ends at a Toiyabe National Forest campground called Green Creek Campground. The drive up can be washboard bumpy in some parts, but that doesn’t stop the hundreds of adventurous motorhomes that make this trek annually. This place features some of the best prime Sierra back roads camping options for RVs.

Another dirt route, Dunderberg Meadow Road peels off to the left. Dunderberg departs  off Green Creek a couple of miles from the highway and well maintained. This route leads to meadows, aspens, picture perfect scenery and much more seclusion. Passenger car accessible, wide graded dirt roads to wilderness edges. Two-track one lane trails lead to meadow edges and more creeks. Very impressive views of the Sierra peaks over here on this side. Meadows are sensitive areas, wonderful for picnics and you should always minimize impact.

Plain old passenger cars can easily make this route deep into the Eastern Sierra aspen canyon. Graded dirt and4x4 could be needed winter months. Backpackers can enjoy easy access to the Hoover Wilderness trailheads. There is plenty semi-primitive camping spots along the way, right on the creek, for free…. so no need to sleep in your vehicle upon arrival.

Autumn Aspen Groves: fall colors peak in October, which is usually when the first snows for the winter season start. November – usually the freeze gets them and lifeless brown leaves dangle, until the Sierra Nevada wind gust blow real good.

Dispersed, primitive camp spots along this main dirt road are on a first come basis. You’ll need a fire permit. Many flat camps are set along the creek in aspen groves, some pines, others have  cubby hole privacy. Large granite valley, big creek, bird, scenery and nature everywhere.  Some folks spend weeks camping out here in the warm weather months. Fishing is a big attraction.

Camping Rivers

More & more people are venturing off the beaten touristy path of Gold Country. Getting outta the developed campgrounds to discover the joys of dispersed back woods camping is a new adventure, not to be taken lightly.

With truck or SUV ownership come some great rewards! Order a good map & go find some dirt roads. Waterfalls, dense forests, secluded creekside camp sites & more await you. Obtaining a camp fire permit is mandatory for this style of camping.

Campfires are often banned in California, due to extreme wildfire danger. Since the gold mining foothills are usually oak and dry grass, with large steep river canyons, extra caution should be given. Always know the fire conditions before you build a campfire. Caldor Camping

Discover the hidden back roads: like Caldor Road off of Grizzly Flat Rd. – up above Placerville CA

Hey, now this is what we’re talking about. Plenty great dispersed camping down by the Cosumnes River & Consumnes Mine Rd. There are hundreds of miles of small roads to discover back behind this historic mining area. Rivers, waterfalls & decent fishing too. Make sure you clean up some litter. This is the only price you pay for the beauty, serenity, peace & quiet & no neighbor campers next to you.

Out exploring these parts, you may run into a dead end road that peters out at some Private Property, which is usually signed & fenced. Make nice with the old crazy miner dude & turn your ass around politely, everything will be okay as soon as you are not within gun shot of him. Yes, there still are plenty of small time mining experts tucked away back here in the hills.

Premium and secluded river side camp sites in El Dorado National Forest

Plenty creeks and rivers run throughout this central Sierra region, so you can fish all day – until your hearts desire. River rafting and river kayaking opportunities are also great reasons to get wet.

Several mountain reservoirs around offer camping and boating too. Eldorado lakes are listed below.
