Horr Pond sites #7-9 are primitive camping areas within Ahjumawi Lava Springs State Park, accessible only by shallow-draft boat from the Rat Farm boat launch (3 miles north of McArthur on a graded dirt road).

Each campsite includes a pit toilet and access to spring water that must be purified, making them ideal for paddlers and anglers exploring the park's 2. 5-mile waterways.

A self-pay envelope system is used for registration at these remote, undeveloped campsites.
