10 Fun Summer Activities in Whittier, Alaska - Avis Alaska

Accessing the town of Whittier requires navigating the Anton Anderson Memorial Tunnel, a unique one-way, multimodal toll tunnel that dictates all vehicle traffic entering and exiting the community. Travelers must plan their itineraries around strict operational schedules, seasonal tunnel closures, and specific vehicle size limitations to ensure a successful arrival into this Prince William Sound gateway.


Essential Logistics and Pre-Trip Planning Requirements

Before embarking on the journey to Whittier, you must reconcile your travel schedule with the unique infrastructure of the Anton Anderson Memorial Tunnel. Unlike standard mountain passes, this 2.5-mile tunnel is shared by both road vehicles and the Alaska Railroad, necessitating a strictly timed traffic flow.



  • Essential Preparation Checklist
  • Vehicle Clearances: Verify your vehicle height and width. The maximum height clearance is 14 feet 6 inches, and the maximum width is 8 feet 6 inches. Oversized loads require a permit and specific transit windows.
  • Scheduling: Consult the current seasonal schedule for the tunnel, as opening hours shift between summer and winter. Traffic direction alternates every 30 minutes.
  • Financial Readiness: Prepare for toll payments. As of current regulations, the toll is per vehicle, with higher rates for trailers and commercial units. Credit cards are accepted, but physical cash can sometimes expedite processing during peak summer traffic.
  • Safety Gear: Pack standard Alaskan roadside emergency supplies, including a high-visibility vest, a tire pressure gauge, and at least one gallon of potable water per passenger.
  • Communication: Download offline maps, as cellular service is intermittent or non-existent in the Portage Valley area leading up to the tunnel entrance.

Navigating the Transit Route and Tunnel Protocols

The route to Whittier from Anchorage involves driving south on the Seward Highway (Alaska Route 1) for approximately 50 miles before turning onto the Portage Glacier Road. The transit through the tunnel is the final, critical step in your arrival process.



Step 1: Navigating the Seward Highway Corridor

The journey begins on the Seward Highway. Exit Anchorage heading south toward Girdwood. This segment of the highway is scenic but prone to heavy tourist traffic and sudden weather changes. Maintain a steady speed and be prepared for potential wildlife crossings, particularly near the Turnagain Arm. Reach the junction of the Seward Highway and Portage Glacier Road. Turn left onto Portage Glacier Road and proceed for approximately 5 miles toward the tunnel staging area.



Step 2: Staging and Toll Collection

As you approach the tunnel entrance, follow the directional signage into the staging lanes. The staging area serves as a holding zone while the tunnel traffic is cleared from the opposite direction.

Pro-Tip: During peak summer months, aim to arrive at the staging area at least 20 minutes before the scheduled opening. This ensures you are at the front of the queue and minimizes the risk of waiting for a subsequent opening if traffic volume is high.



Step 3: Executing the Tunnel Transit

Once the light turns green, follow the signal instructions from the tunnel operators. Maintain a consistent speed of 25 miles per hour throughout the 2.5-mile passage. Do not stop inside the tunnel unless an emergency occurs. If you encounter mechanical failure, remain in your vehicle and activate your hazard lights; tunnel personnel are equipped to handle breakdowns via radio communication.



Step 4: Final Arrival into Whittier

Upon exiting the tunnel, you will emerge into the Whittier harbor area. Be aware of pedestrians and commercial traffic near the cruise ship docks and the Anton Anderson Memorial Tunnel arrival zone. Follow local municipal signage to reach your specific destination, whether it is the harbor, the train depot, or the Begich Towers.

Managing Transit Challenges and Field Failures

Even with careful planning, environmental or mechanical variables can impede your arrival. Addressing these issues immediately is crucial for safety.



  • Scenario: Unexpected Tunnel Delay

  • Root Cause: A freight train passage or maintenance work has extended the tunnel closure beyond the posted schedule.

  • Actionable Fix: Monitor the official Alaska Department of Transportation tunnel status website or listen to AM 530/1610 for broadcast updates. Use the waiting time to perform a final vehicle walk-around check before the gate opens.

  • Scenario: Vehicle Width or Height Violation

  • Root Cause: Attempting to enter the tunnel with an oversized vehicle or improperly secured roof cargo that exceeds height limitations.

  • Actionable Fix: If you realize your vehicle exceeds the dimensions, stop at the staging area and contact the tunnel operator immediately. You may be required to secure a pilot car or wait for a specific off-peak slot if a permit was not previously processed.

  • Scenario: Overheating During Staging

  • Root Cause: Extended idling in the staging lanes during summer months, especially with heavy loads or older cooling systems.

  • Actionable Fix: Monitor your temperature gauge during the wait. If the engine begins to run hot, turn off the engine and use the vehicle’s heater to dissipate excess heat into the cabin until the tunnel gate cycle initiates.

Frequently Asked Questions



Can I walk or bike through the Whittier Tunnel?

Yes, pedestrians and cyclists are permitted to travel through the tunnel, but they must do so within a designated transit window. It is required to call the tunnel dispatch office beforehand to coordinate your entry and ensure you are not present during a train transit or heavy vehicle movement.



How much does it cost to drive through the Whittier Tunnel?

Toll pricing varies based on the vehicle type and the season. As of the current fiscal period, standard passenger vehicles typically pay between 13 and 15 dollars, while trailers and oversized commercial vehicles incur higher fees. Check the official Alaska Department of Transportation website for current rates.



What happens if I arrive after the last tunnel crossing?

If you arrive after the final daily tunnel crossing, you will be unable to reach Whittier until the tunnel reopens the following morning. There are no overnight accommodation staging areas specifically for tunnel-bound vehicles, so it is imperative to plan your travel to arrive before the final scheduled slot.



Does the Alaska Railroad provide an alternative to driving?

Yes, the Alaska Railroad offers passenger service to Whittier via the Glacier Discovery Train. This is a common alternative for travelers who prefer to bypass the tunnel driving requirements, as the train tracks are integrated into the tunnel transit system.

Plan your transit today by reviewing the most recent seasonal schedule for the Anton Anderson Memorial Tunnel to ensure a seamless arrival at the Prince William Sound. Reliable coordination with tunnel logistics remains the single most important factor for a successful trip to Whittier.
