The lake view next to the camping site was amazing. Tried pizza near to the camping site and it was delicious

Beautiful spot right next to Diamond Lake. There was enough distance from other sites so it was quiet. The morning sun hits the picnic table and cooking spot so it helps warm you up from the chilly night. The biggest downside was having algae in the spot where our dog was swimming; we were worried it would make her sick. We couldn't keep her out of the water so we packed up early and left.

Site was large but the drive through was up and down a hill and the ONLY level part was about 15'! No way I could live the coach, even by adding blocks under the jacks. So they happily moved us to a larger and flatter pull though for our stay. THAT was nice.

So many trees down in the campground. Needs cleaned up for sure! A bit to strict on check in. Couldn’t come in until strictly at 2. Even if your space was empty.

Although this is an ideal location for exploring Crater Lake, they let way too many people camp here so it's kind of run down and poorly maintained. Bathrooms are dirty and lack toilet paper. Garbage bins were overflowing. There are not enough camp hosts to enforce rules so people set up tent villages in the margins between sites and let dogs run off leash to poop in my campsite.

Nice campground with appropriate distance between campsites. I was close to the pizza/ ice cream shop so that was a plus!

We camp here for a few days, lake is not the cleanest but water was warm. I would definitely stay again, I was expecting more mosquitos that what I really saw, repellent is a must.

A beautiful place to camp. However, overall maintenance of the campground could be improved. The potable water system within our campground loop was not working. The restrooms in the adjoining loop were not functioning due to equipment failure. The camp host was friendly and helpful.
