We recently stayed at Lopez Lake with our three children (all under age 9). The sites are easy to navigate, the wildlife flourishes throughout the area for some fun viewings, the rangers and staff were super helpful and there was plenty of room for the kids to run around. The Lake was low, but this is California so, ya know. Water was chilly but the kids were soldiers and it was a good time and extra relaxing for us parents. For $30 a night, it’s worth every penny!
