The peak ferry season starts Saturday, May 1, and that means occasional users will pay more to ride ferries.

Washington State Ferries will implement a 25 percent surcharge applied to full fare vehicle/driver tickets. The peak season surcharge doesn’t affect passenger fares or frequent user, multi-ride fares, except on the Anacortes/San Juan routes.

The one-way, vehicle and driver fare at Clinton will climb from $7 to $8.75 and the same fare at Keystone will climb from $9.15 to $11.45.

On the Anacortes/San Juan routes passenger fares are hiked only 20 percent during the peak season, but vehicle/driver fares jump 35 percent, according to a news release from the ferry system. These routes also have day-of-the-week pricing, making travel less expensive from Sunday through Tuesday.

The peak-season ferry fares will be in effect from Saturday, May 1 through Saturday, Oct. 9.
