Last Gas and Supplies Before the Park: Marblemount vs Concrete vs Rockport
Last updated: March 2026
If you are driving SR-20 toward Newhalem and the North Cascades park corridor, the fastest useful answer is: do your main grocery/supplies stop in Concrete and top off fuel in Marblemount before continuing east. NPS pages for camping in the park complex repeatedly state that gas, ice, firewood, and other services are not available in the park complex and that the nearest services are in Marblemount.

Quick Answer:
- Concrete - do the larger food and supplies run before you get farther east.
- Marblemount - top off fuel and grab final supply items before entering the park complex
Details:
Concrete: better for the bigger stock-up
Concrete comes before Rockport and Marblemount when driving east on SR-20 toward Newhalem. It is usually the better place to do the larger supplies stop so you are not trying to solve your whole trip in Marblemount right before the park corridor.
- Best for: groceries, cooler loading, picnic food, camp consumables, and a more complete resupply before Marblemount.
- Where it fits: use Concrete first, then finish with a short Marblemount fuel stop before Newhalem.
- Practical detail: if you are carrying cold items, do the bulk food stop in Concrete and a final ice/top-off stop later in Marblemount.

Rockport: useful stop for lunch or a leg stretch
Rockport sits before Marblemount in the SR-20 flow. It can be useful for a meal break or pacing stop, but it is a weaker choice as your only fuel-and-supplies strategy for a park day unless you have already checked exactly what is open.
- Best for: meal break, quick reset, or splitting a long drive before Marblemount/Newhalem.
- Where it fits: optional stop between Concrete and Marblemount.
- Practical detail: if weather shifts or you are behind schedule, skip Rockport and preserve time for Marblemount fuel plus the park corridor.
Marblemount: last practical supply stop
Marblemount is the key final service stop before North Cascades National Park in the west-to-east SR-20 flow. NPS camping pages and the Goodell Creek campground page both state the nearest services to the park complex are in Marblemount (NPS camping) (NPS Goodell Creek).
- Best for: final fuel, ice, drinks, snacks, and “forgot one thing” stops before Newhalem.
- Do this here: top off fuel even if you think you have enough for the day.
- Do not do this here: large grocery wandering if you are trying to keep a sightseeing schedule.
