When it comes to lodging, I let everyone decide what works best for them. Some people like to stay in hotels in Taos. Others like to cut cost by camping out at the Orilla Verde State Park. Others bring camper trailers and RVs. In the past, some have stayed at Ojo Caliente, Sipapu, or found Bed & Breakfast inns in Dixon, Pilar, Embudo or Chimayo. There are a variety of options.
I will typically will get a campsite on the State Park Friday or Saturday night, depending on when I arrive. Campsites are booked first come, first served, so advanced reservations are not allowed. Anyone is welcome to stay at my campsite, provided we don't exceed the limits.
Campsites at the Orilla Verde State Park vary from primitive to full RV setups. Most have enzyme or flush toilets, and one campground has hot showers. Bring $2-3 in quarters. It's not necessary to stay at that campground to use their shower.
If you camp out, bring the usual car-camping equipment; tent, sleeping bag, mattress/sleeping pad, ice chest, etc.
