Vallø is just 5km south of Køge, and most visitors return there to sleep, though there is a perfectly passable B&B in Valløby, Vallø's newer section 2km east, along with a more comfortable alternative 3km north in Egøje. Note that Køge-Vallø Camping is actually in Køge. Sleeping at Vallø Slotskro is possible as part of a full-on gastro-stay.
