Moulay Idriss is in Morocco.
Grand taxis from Meknes can be found across from the French Institute, approximately half a kilometer west of the Gare Al Amir Abdul Kader train station. A taxi ride from the train station to the taxi station should only cost 7MAD. A Grand Taxi to Moulay Idriss from Meknes costs 10MAD per person, or 60MAD for a whole car. The ride takes about 30 minutes. There is also a public bus from Meknes to Moulay Idriss (#15, 7 MAD), leaving from the bus stop near the same Grand Taxi station. Grand Taxi drivers will also offer a round-trip tour to Moulay Idriss, Volubilis, one other site (didn't catch the name), and back to Meknes for 100-150MAD.
The town is small enough to negotiate on foot. A couple roads pass through town, but most of the hotels and other destinations are in the medina, and therefore accessible by foot only. None of the medina streets are currently on Google Maps. The taxi stand is on the road that enters town from the northwest ("Gare Routière" on Google Maps). The three-way intersection just uphill from the taxi stand is the main intersection of the town. Head to the right (east) to find restaurants, the main plaza, and the mausoleum of Moulay Idriss I ("Tombeau de Moulay Idriss 1er" on Google Maps).
-Peek through the gates into the Mausoleum of Moulay Idriss I, just off the main plaza. No entrance for non-Muslims.
-Check out the only round minaret in Morocco. Quranic script encircles the minaret. Depending on who you ask, five (or six) pilgrimages to this mosque (or to the Mausoleum of Moulay Idriss I) is equivalent to one pilgrimage to Mecca. Wander around with eyes skyward, or ask directions from a local.
-Visit the nearby Roman thermal bath , about a fifteen minute walk outside of town.
-Get lost the maze-like streets and alleys of the old medina
-Eat with the locals at one of the many cafes near the plaza
-Walk up behind the city to one of the many beautiful panoramic overlooks
-Walk to the nearby Roman ruins of Volubilis . The walk takes about 45 minutes one way. Directions: Walk up the main street in Moulay Idriss. After ~400 m, take the first left out of town, and bear left at the immediate fork in the road. You'll pass Restaurant La Baraka on your left. Continue walking on the dirt road through olive groves. Don't take any turnoffs, and eventually the dirt road will switchback down to the main paved road. Go left (south) on the paved road, and 100 m later take your first right toward Volubilis. The main entrance to the ruins is ~600 m down the road on the right. Entrance is 10MAD, open from 8 am to sunset. Wandering through the ruins takes a couple of hours. You can exit the ruins through the back gate (explain to any guards that you came on foot). Head back to the main paved road, turn right, and ~400 m later you'll be back at the dirt road to Moulay Idriss. Bring snacks, water and sun protection.
