Great place for all. Amenities are great. Location and sites are beautiful and spaced out well. Lake is not for watersport type play but great for swimming as speed limit for boats is 10mph, it keeps wakes minimal for shore play.

We had a great time despite the haze in the sky due to fires. First trip to Diamond Lake and Crater Lake. No cell service meant true camping and hanging out, connecting through conversation and fun activities. My only complaint/concern was the lake itself. One dock we found a sign that warned of a harmful poisonous algae but not posted on the dock we were using. And this after the kids had swam. We checked the alae blooms for Diamond Lake prior to camping. A notice of alae status included with your email reminders of reservations would help clarify.

Beautiful and large spot! Be prepared to have to come in the one way street the wrong way to get your trailer into the spot. Only complaint about this spot, that the driveway angle is wrong for the one way street.

The lake is beautiful, the campground is tired. The sites are very dusty with little grass. Makes it very dirty.

If in a motorhome it would be helpful to have a tow vehicle. Even though there is a lot to do it also involves a lot of walking.

While staying at the campground for 1 week the garbage containers were overflowing for days and not picked up. The toilet in the mens bathroom was plugged up for days. On the door of the bathroom was a sign telling users to email the forest about problems as the cleaning was under contract with a private company. First I couldn't email as I didn't have good phone service or internet. A forest service person visited the restroom but nothing was done about the plugged toilet. I spent 37 years managing campgrounds on nation forest and this is not public service. Toilets should be checked and cleaned without the public needing to notify the forest service to get it done. Other than that the stay was good. The trail around the lake was nice and the campground was peaceful. I plan on returning next year but hope they do better with the cleaning.
