Art's Dune Tours. Art's Dune Tours has been taking eager passengers into the dunes of Province Lands since 1946. Bumpy but controlled rides (about one hour) transport you through sometimes surreal sandy vistas peppered with beach grass and along a shoreline patrolled by seagulls and sandpipers. On Sunday there is a special Race Point Lighthouse Tour; or head out at sunset for a stunning ride, available with or without a clambake feast. 4 Standish St., Downtown Center, Provincetown, MA, 02657. 508/487–1950 or 800/894–1951. www.artsdunetours.com. Regular tours start at $27.
