  1. My family and I discovered Mammoth in 1980 especially the ever so beautifully set campground Twin Lakes I would love to take pictures of the lake with the waterfall always in the background many things have changed the campgrounds are full congestion everything quitets down as the sun sets you can smell coffee n bacon frying in the mountain air have been going ever since

  2. itsmebeccalee@gmail.com says:

    Does anyone know when Twin Lakes campground will be open again?

  3. Kristen Aldrich says:

    It shows first come / first serve … what’s the probability of getting a spot Mon -Thursday ? Also what is the fire restrictions , can you have a camp fire ?

    • Hi Kristin,
      I’ll actually be camping there this Thursday through Tue. If I remember, I’ll check to see if any first-come first-serve campsites are available Sunday/Monday and try and let you know (posting here). With that said, the reservable sites have been sold out soon after it opened and through the summer. That tells me that the first-come, first-serve sites will be popular (even mid-week). I’d say your chances are no better than 50/50 at best that one would be available for a Monday arrival.

  4. Was planning on going camping with my family this weekend how early would we have to be there to try to get a first come first serve spot? Also my kids are 4,8 and 10 can they get in the water there ?

    • Hi Celina,
      I just returned from camping (Fri-Tu) at Twin Lakes campground.The first-come, first-serve campsites fill up very fast (weekend or midweek). There are usually 5-10 vehicles/campers in line by 8am each day waiting to enter and grab a first-come first-serve campsite as soon as someone leaves the site. I would get there no later than 8am your planned day of arrival. Friday arrivals will be very tough to get a site because most or already taken Thursday.

  5. Is it difficult to get a trailer to the upper campground area? Specifically site 85? Last year, I remember it looking narrow that way but we were down in the flats…

    • Hi Jen,

      You should be fine navigating your trailer in the upper section of Twin Lakes campground (to campsite #85). FYI – the driveway length is listed as 40 feet (maximum vehicle length is 30 feet), and you can have up to two vehicles (including tow vehicle) at the site.

  6. is there phone signal there at the camp? want to move home office to campsite!

  7. Hi,

    Im looking to come up either Friday or Saturday to camp for a couple nights this weekend but everything is first come first serve. Any idea on what day and best time to come to land a spot or if it’ll be crazy to land a spot will there be other possible campsites that might have space?

    Thanks in advance!

    • Hi Bardia,
      Most likely, all of Twin Lakes first-come, first-serve campsites will be taken by Thursday night – through Labor Day weekend. All reservable campsites are taken too. Sorry about that.

  8. Hi, how hard will it be to get a first come first serve campsite September 11 to 13th? What time would be best to arrive to improve the chance of getting a spot?

    • Hi Jenny,

      All reservable campsites at Twin Lakes are taken Sep 11-13, so this tells me it will be very popular that weekend . . . and probably each weekend until the campground closes for the winter. Your best bet would be to arrive Friday morning around 7-8am and check with with the camp host to see if any of the first-come, first-serve campers will be leaving. If so, you can get ask to get a site and/or get in line. Others will be there early on Friday as well.

  9. Timothy L. Barela says:

    if I arrive on Wednesday 9/9/20 what are the chances if getting a campsite.

    • I say your changes are very good to almost for sure with a September 9 (Wednesday) arrival that you will get a campsite at Twin Lakes campground. Have a great time!

  10. Planning to go to Twin Lakes the middle of September. Do you have any suggestions on the campsites. We will be tent camping. The more secluded the campsite the better. Thank you

    • Hi Gerald,
      Our favorite campsites at Twin Lakes Campground are: 5, 6, 7, 19, 21, 29, 32, 39, 40, 43, 45, 46, 46a, 46b, 46c, 46d, 47, 48, 49, 52, 57, 61, 62, 68, 69, 71, 73, 79, 81, 82, 85, 90, 93

      With that said, the best of the best (in our opinion) and those that are more secluded/private include 46, 46a, 46b, 46c, 46d. These are also really close to the water. Other nice ones (for privacy) include 43 and 45.

  11. Planning to go to Twin Lakes in an RV. Is there a dumpsite and potable water available?

  12. Hello, looking to book 5 sites in the summer.. which sites to you think are closest together? Thanks

    • Hi Rachel,
      Getting 5 Twin Lake campsites reservations are going to be tough for this summer, and getting 5 in close proximity will even be tougher. With that said, I’d recommend 41, 43, 44, 45 and 46. Although only 4 sites – 46a, 46b, 46c and 46d are really nice and close to the water. 79, 80, 781, 82 and 83 have a pretty close grouping too. Best of luck!

  13. What is the driveway length of site 44? We have a reservation, but just bought a bigger camper and are worried it won’t fit. The camper is a 16foot box, 20 foot total length.

  14. Gena M Steward says:

    Hi-I have a 34′ 5th wheel and I booked campsite 55 (it notes a 40′ driveway) BUT is there enough room to back in with the front end swing of the truck?? How wide is the road?

    Thank you!

    • HI Gena,
      We’re not located up at Twin Lakes campground and don’t have anyone there, but from experience I know the camp roads are a tad narrow. Campsite 55 is at the intersection of two camp roads, so there may be room to maneuver your rig. You could try calling to talk to someone: 760-934-5795.

  15. Mac Herbert says:

    Do you have any first come first serve spots in Twin Lakes?

  16. Roland R says:

    We will be staying at 46A this summer. Is there a restroom located near sites 46a, 46b, 46c, & 46d?

  17. Miriam Galicia says:

    Where do we check in for First Come First Serve Campsites? Where should we get in line? Are we supposed to go to a specific campground?

  18. I believe there are no longer any First Come First Serve sites at Mammoth Twin Lakes. This was according to the camp host on August 13, 2021. The reason was people fighting over the available campsites.
    You can verify this by checking the reservation system. No “FF” show up except for a few cancellations.

  19. Hi, we are planning to stay 1 night on September. We are 6 adults and 1 little Girl (Who turns 1 year the end of August) Does she count for the maximum capacity)? If I could book just one site would be perfect but I dont want any trouble

  20. I was just able to score site 46d. Says 33 ft site. We have a 28ft trailer. If I remember right, it seemed like a small, hard to maneuver entrance to the 46s. Does anyone have any experience or advice? Can we fit? Are there the short stumps along the entrance? They make it hard to turn the travel trailer.
    Thank you.

    • Crystal G says:

      Hi Jen, we also have upcoming reservations for 46d! Did you already go? Curious how your trailer fit as we have a similar size. Also, was this site close to the water? TIA

  21. Chelsea T. says:

    How swimmable is the lake? Is there a “beach” area near any of the camp sites where kids could play in the sand or on the shore?

    • Hi Chelsea,
      Twin Lakes isn’t a good swim lake and there are no beaches there. Your best bet is to drive 2.5 miles to Horseshoe Lake. It has a swim beach/swim area, but the water is a bit chilly even in the summer.

  22. michaelmcmanama@gmail.com says:

    Campsite 46c says 19ft max trailer, anyone know how strict this is? Do you think a 20-21ft trailer would be denied entry?

  23. Greetings! I have spot 60, the site says 1 vehicle max but the drive way is 40+ feet. Is it still possible to have 2 cars there?
