Glacier National Park — 7-Day RV Trip From Kalispell

Going-to-the-Sun Road is the most spectacular drive in the National Park System — and the one road your RV probably can’t take. That paradox defines a Glacier trip: the park hands you a 50-mile cliff-edge ribbon over the Continental Divide, then tells anything over 21 feet to turn around at Avalanche Creek. Plan for that one rule and Glacier is the finest week of RV travel in the Lower 48. Ignore it and you’ll be reversing a 30-foot Class C on a shelf road with a thousand-foot drop. Here’s the 7-day loop from Kalispell, rebuilt for what actually changed in 2026 — because a lot did.

What changed for 2026 (and why it matters)?

Two big shifts: Glacier dropped vehicle reservations entirely, and the free Logan Pass shuttle became a $1 ticketed one. If you’re working off an older guide, throw out the timed-entry ticket advice.

• No vehicle reservations. For 2026 the park suspended its timed-entry system on Going-to-the-Sun Road and at Many Glacier and Two Medicine. You need only a park pass. The catch: the park now manages crowds by temporarily closing entrances when lots fill, so arrive before ~8 a.m. or after ~4 p.m.
• The shuttle is now $1 and ticketed. The old free hop-on/hop-off is gone. Tickets release on a 60-day rolling window (May 2, 8 a.m. MDT) and mostly at 7 p.m. the night before (from June 30). There’s also a new 3-hour parking limit at Logan Pass from July 1.

What does the trip look like at a glance?

Seven days, about 400 miles, one enormous park, best run July through mid-September.

• Launch: Kalispell, MT (FCA airport)
• Distance: ~400 miles round trip
• Recommended class: Class B under 21 ft to drive the full road, or Class C 26-30 ft with the shuttle
• All-in budget: $2,800-$3,200 for two people
• Best months: July–mid-September (road fully open, campgrounds running)

Day-by-day route

Day 1: Kalispell → Apgar

Pick up the rig, provision in Kalispell, and drive the 50 minutes to Apgar on the foot of Lake McDonald. Walk the pebble beach at sunset — the water goes glass-still and the peaks light up in the classic Glacier frame. Camp: Apgar (~$25).

Day 2: Going-to-the-Sun Road

The headline day. If you’re in a sub-21-ft van, drive the whole road to Logan Pass and hike the Hidden Lake Overlook (2.7 miles round trip, mountain goats likely). In a bigger rig, drive to Avalanche Creek, hike the Avalanche Lake trail, then catch the $1 shuttle up to Logan Pass — book the ticket the night before. Either way, be moving early to beat the entrance closures. Camp: Apgar.

Day 3: Apgar → St. Mary

Drive around the park’s south end on US-2 and US-89 (the only route for a big rig — 100 miles, 2.5 hours) to the drier, wind-scoured east side. Set up at St. Mary (reopened for 2026 by July 1) and pull over at the Wild Goose Island overlook for the most photographed view on St. Mary Lake. Camp: St. Mary ($25).

Day 4: St. Mary waterfalls

Walk to St. Mary Falls and Virginia Falls (about 3 miles round trip through the burn-regrowth forest), then ride the shuttle up to Logan Pass from the east for the alpine meadows. Camp: St. Mary.

Day 5: St. Mary → Many Glacier

A short hop north to Many Glacier — the park’s crown jewel, freshly reopened mid-May 2026 after a year closed for the Swiftcurrent project. Afternoon on the Iceberg Lake trail or a Grinnell Lake boat-and-walk. Camp: Many Glacier (~$25).

Day 6: Many Glacier full day

The big one: Grinnell Glacier (about 10 miles round trip, strenuous, and worth every step for the meltwater lake at the toe of the ice). Save the afternoon for the Swiftcurrent Lake boat tour and bear-aware walking near camp. Camp: Many Glacier.

Day 7: Many Glacier → Kalispell

Drive the 2.5 hours back around to Kalispell, dump tanks, refuel, and return the rig.

What does it cost all-in?

About $2,800-$3,200 for two — Glacier is the best-value marquee park trip in the Rockies. Our July 2026 pull of 3,398 live listings put the national median at $150/night; Montana’s gateway markets run above that, so price a Kalispell Class C around $200-$230. Treat these as a research-date snapshot.

Line item	Amount
Class C rental: $210/night × 7	$1,470
Booking fees + insurance + cleaning	$400–$550
Fuel (400 mi @ 7 mpg @ $3.85/gal)	$220
NPS America the Beautiful pass	$80
Campgrounds (NPS ~$25 × 6)	$150
Logan Pass shuttle ($1/person) + Many Glacier boat (~$30/person)	$60–$65
Food, propane, dining (2 people)	$400–$600
All-in, 7 days	$2,780–$3,135

Note what’s not here anymore: the vehicle-reservation fee older guides list is gone in 2026. Our RV rental cost guide covers the full method.

Which RV class fits Glacier?

This is the one park where the smallest rig wins — a sub-21-ft Class B is the only kind that can drive the whole of Going-to-the-Sun Road.

Class	Glacier fit
Class B under 21 ft	Best — drives the full road, fits every campground
Class C 22-28 ft	Fits campgrounds; ride the shuttle across the road
Class C 30 ft	Fits Apgar/St. Mary/Many Glacier; drive around, shuttle up
Class A 35+ ft	Limited NPS access — plan on private parks outside the gates

Families who need the space take a Class C 26-28 ft and lean on the shuttle; couples chasing the full drive take the van.

What goes wrong out here — and how do you handle it?

Most Glacier headaches are timing and weather, both manageable.

• Entrance closed when you arrive: with reservations gone, lots fill and gates close temporarily — beat it by entering before 8 a.m. or after 4 p.m.
• Road not fully open: Going-to-the-Sun typically opens end to end in early July; a June trip may find the top still plowed shut.
• Wildlife on the road: bighorn sheep, mountain goats, and bears stop traffic — keep your distance and your patience.
• Thin cell service: near-zero at Many Glacier; download maps and shuttle tickets before you lose signal.
• Cold nights: even July drops to 35-40°F on the east side. Pack real layers.

Bottom line

The 7-day Glacier loop from Kalispell is the most dramatic RV week in the country — if you respect the 21-foot rule and the new 2026 rhythm. Rent a van to drive the road or a Class C and ride the $1 shuttle, skip the vehicle-reservation worry entirely this year, confirm Many Glacier and St. Mary are on your dates, and enter early.
