Grover Hot Springs, Markleeville, CA

This spring, which isn't being named, is not actually located at Carson Pass along Highway 88. Instead, it can be found on foot about 1.8 miles from Carson Pass. This is not the best location for people who are looking to fill 5 gallon jugs. However, in return you can take a subalpine hiking trip, enjoy beautiful views, subalpine lakes and perhaps one of the most spectacular wildflower shows on earth.
The water comes from the spring and is much better than that of many lower altitude options. It has a unique flavor that is hard to describe. It's probably the most refreshing water that I have ever tasted. It is unique in that it can satisfy you in a way other water cannot. The spring is situated in a stunning location as well. The spring is situated at 8900 feet elevation and is surrounded wildflowers. It is close to Lake Winnemucca, which is a very popular lake.
It's easy to locate the spring. Park at the Carson Pass trailhead. The log cabin information center is just a short walk from the trailhead. Follow the Pacific Crest trail for about a mile, until you reach the fork that leads to Frog Lake. You should not veer left on Pacific Crest Trail. Instead, follow the signpost to Lake Winnemucca.
After passing through open woodland for about a mile, you will reach a large meadow to the west of Elephant's Back. This is the place where wildflowers peak, so be sure to visit between mid-July and mid-August. You will come to the end and cross a small stream. The trail will then turn right. This little stream is actually the product of the spring. It is about 50ft away from the spring, once you have crossed it. It is a hole, from which water flows up. You can refill your bottles right here. It might be a good idea to fill your bottles here before heading further (like to Lake Winnemucca, Round Top Lake) so you don't have the burden of carrying water all that far. However, you'll still need to bring your water back about 1.8 miles. It's almost all downhill.
