I won't recommend it for big bikes or those who don't like it rough, but there are quite enjoyable commercial hot pools off the Creel/ Guachochi road. Turnoff to the right about 30km further south from the old Batopilas/Samachique turnoff is signposted.
There is then a rough track of 19km (40minutes) down into a canyon to a set of private hot pools. Camping is also available as are a couple of cabins. Couple of bucks for the hot pools.
