After doing some reading, we are considering seeing the canyon area as we travel between Arequipa and Puno. I'm thinking we would enjoy one or two nights in the canyon. I have looked at several tours, but most only offer one night (which may be enough) and anything longer includes treks. My husband is unable to walk long distances at one time so he would need some flexibility in how far we hike. I would welcome any advice on tours that may be a good fit or a couple of the hotels/lodges that have some nice hiking trails to enjoy without a guide. I have read that you can just book the bus trip to the canyon without tours. I wonder would we be able to enjoy the scenery from the bus and enjoy a stay in a couple of the villages/towns. Is it also possible to get a guide for a few hours from the hotel/lodge where you stay in the canyon? We are trying to keep our budget low to mid range and we are early 60s. We are good with most accommodations as long as they are clean and comfortable with a private bath (have done shared baths a few times). We can be swayed by beautiful scenery and surroundings.
