Diamond Lake

Diamond Lake is really cool. Great mountain views and decent fishing. We lucked out on the smoke which I think scared some people off as the place was pretty empty. There was an algae bloom so we didn't swim which was a bit of a bummer but camping lakeside is really nice. Plenty of trees for hammocks and great shower facilities.

Lovely campground, and we stayed 50 feet from the water. It was great to be able to shower in the morning. We stayed at Mazama Campground the next night and decided we'd always stay at Diamond in the future. It's much better - more woodsy, beautiful, and secluded with less dust and better amenities.

After lodging complaints over the past few years, I think this may have been our last visit. 2 different households travel 4.5 and 7 hours with hope to enjoy the great Diamond Lake which once was.
While the general area is replete with outstanding natural beauty, the campground has been increasingly neglected.
1. Sites are left trashed for the next visitors. Sites used to be "groomed" prior to new arrivals - no more.
2. Toilets are in decent shape but the men's urinals continue to smell and look bad with built up urine scale.
3. The bathroom on G Loop (both men's and women's) nearest the Registration Office continues to be without power and lighting for the past few years.
4. Picnic tables are in need of levelling. It's hard to enjoy meal prep, dining, and other table-related activities when stuff keeps falling over or rolling away.
5. Recreation.gov shows that campfires are allowed, but they are NOT (at least when we visit each of the past 3 years)! If you want a fire to warm you in the chill of the morning, you can only use your own propane fire pit.

The only saving grace (that justified 2 stars instead of 1) for the campground facilities that we experienced were the showers. They seemed clean, functional, and with enough warm water.

All said, there must be better campground facilities out there, but like I said earlier - This may have been our last at Diamond Lake.

We stayed here during our visit to Crater Lake. It was the perfect distance away if you don’t luck out with a camp spot inside the state park. Our campsite was so picturesque and right on the water! Being right across from the bathrooms had its pros and cons; the neighbors were a tad noisy at night. The water splashing on the rocks at night can either be music to your ears, or keep you up all night. No mosquitos during the first week of September but as soon as the sun goes down the flies, moths, etc come on like crazy! Our citronella candle turned into a flying bug graveyard and you couldn’t have light on without being bombarded. The trash cans were super protected and the showers were alright. Overall, worth the money.

I stayed at H03 and it was incredible. The campsite was clean and was sufficiently private. It’s a short walk to the lake if you want to watch the sunset. The toilets were clean and well furnished. Great place to stay if you are looking to visit Crater Lake as well.

Stayed in B loop during late August. Fishing wasn't great due to the algae bloom, but the weather was spectacular. However I had truck engine troubles and had to leave for repair--this ended up taking several days out of my trip that I couldn't avoid. Terrible! But the camp host John was so awesome he not only helped me find an auto repair nearby (Well I say nearby, but since this is so rural the closest is in Crescent haha), he also watched out for my camper while I was away. Such a great dude.

The individual campsites are very large and the campground is huge (like 100+ campsites). I went during a weekend that wasn’t crowded (most of the reserved sites were empty, likely due to wildfire concerns) so it felt very secluded. That might be different with a packed camp. Diamond lake is stunning and my only complaint is that I wished I had gotten a site right along side it instead of right by the road listening to traffic. For anyone reading this, the “K” section is by the lake and “H” borders the street.

Nice campground with large sites and most sites if not lake front have lake views. Biggest negative is a lot of the sites/driveways are on a big slant. If your RV or trailer is much over 20’ this will be a leveling issue.

Beautiful and quiet.

The lake is pretty
