This park was a nice suprise for us - it offered good activates, clean facilities, and nice campsites. Big Rigs need to be careful with low hanging branches near site 7 otherwise, you'll be ok. Sites 2, 4 & 6 are in an open area; rest are in a wooded setting. 28 is a nice non-elec site. 24, 22 & 20 were nice elec sites. (#24 was especially roomy) 10, 12 & 13 seemed a bit snug to us. Several very interesting hikes. Get the "Banning Quarry Self-Guided Trail" pamphlet at the Ranger Station and walk the Quarry Loop trail. Nice trail (old rail road bed) takes you past relics from the late 1800's when pink "Hinckley Standstone" was mined here and used for high-end building materials. Walking past the remains of the Cutting house, Power house, Rock Crusher, seeing the blast holes in the quarry, the unfinished rock, the tailings, and reading the pamphlet is almost spooky! Hundreds of people worked here and now...nothing but the ruins. Suggestion: Take the Spur Trail up from the quarry rather then face all the stairs at the North end of the Quarry Loop. Kettle River roars through "Hell's Gate" and there is a nice outlook called "Teacher's Outlook". Park is very well maintained. We told the ranger about a paper-wasp's nest across from our site... 30 minutes later a ranger pulls up in a truck, waves at us, sprays the nest, knocks it down from the tree and stomps on it, he waved again as he saw us all standing in our RV applauding him! Very friendly staff there. Some cell phone coverage; no Blackberry coverage. No highway noise however some minor noise at night from a rail road several miles away. We camped here in a Motorhome.
