I've stayed at the Rock Gardens (No Name).
It was nice, but kind a expensive. Seem like it was abt. $28.00 a night for a tent site. Right on the river, but that also means right on the railroad tracks too. Abt. 20 miles up stream toward Burns the BLM has some free sites along the river (same train tracks) pit toilet and table. Have done both. It depends on if you want a shower, closer to town and the wave, or if yer cheap like me. We're coming back again Thurs. Fri. and Sat. and staying at Burns. Ron.
