The old Route 66 town of GRANTS , fifteen miles west of Ácoma, holds half a dozen budget motels, including a good Super 8 , 1604 E Santa Fe Ave (tel 505/287-8811; $35-50). In the heart of town, the Mission at Riverwalk , 422 W Santa Fe Ave (tel 505/285-4632), is an appealing converted church that now doubles as a community theater and healthy café, serving sandwiches, smoothies and coffee. The local visitor center doubles as the comprehensive and enjoyable New Mexico Museum of Mining at 100 N Iron Ave (May-Sept Mon-Sat 9am-5pm, Sun 9am-4pm; Oct-April Mon-Sat 9am-5pm; $3; tel 505/287-4802, ), offering a chance to descend into a mock-up of one of the region's many uranium mines .
