Know Before You Go
Planning a visit to Glen Iris Inn during October?
Fall is one of the most beautiful—and busiest—times of year at Letchworth State Park. Peak foliage weekends can bring very heavy visitation, traffic congestion, and temporary traffic controls or rerouting within the Park.
If you are staying overnight, dining at Caroline’s, or visiting Letchworth for the day, please plan ahead and allow extra time to reach your destination.
Park traffic conditions can change throughout the day based on visitation and congestion. We recommend checking the latest information from New York State Parks before you leave home.
What We Want You to Know

Note that Glen Iris Inn and Caroline’s are located inside Letchworth State Park, and it may take more time than usual to reach the Inn from the Park entrance due to the popularity of fall foliage, which can also mean significant traffic and changing traffic patterns within the Park.

Frequently Asked Questions
Why is traffic so heavy at Letchworth State Park in October?
October is peak fall foliage season at Letchworth. Visitors come from throughout the region and beyond to see the waterfalls, gorge and spectacular fall colors.
On the busiest weekends, the number of visitors can be significantly higher than normal, which can result in traffic congestion, temporary traffic controls and changes to how vehicles move through the Park.
Plan for more time than you would during a typical visit.
I have a reservation at Glen Iris Inn. Does that guarantee I can drive directly to the Inn?
Your hotel or dining reservation is confirmed, but your reservation does not control Park traffic conditions or entrance access.
Note that Glen Iris Inn is located inside Letchworth State Park, and it may take additional time than usual to reach the Inn from the Park entrance.
During periods of heavy visitation, the Park may manage traffic and redirect vehicles.
If you have a reservation, allow plenty of extra time to get through the Park and reach the Inn. Make sure you have your overnight or dining confirmation and enter through the Portageville gate whenever possible. With a confirmation, you are able to drive around the closure signs, go to the gate attendant, and they will let you through.
Which entrance should I use to get to Glen Iris Inn?
The Portageville Entrance is the normal access point for Glen Iris Inn, Caroline’s restaurant, the Museum, and the Middle and Upper Falls area.
However, traffic patterns and entrance access can change during peak periods.
Always check the latest Park information before you travel rather than relying solely on your GPS.
Can Google Maps or GPS tell me how long it will take to get to the Inn?
GPS can help with navigation, but your estimated arrival time may not account for traffic controls, temporary rerouting, or congestion within Letchworth State Park.
During peak October weekends, don’t rely on your GPS arrival time alone.
Give yourself a significant time cushion.
How early should I arrive?
No single arrival time works for everyone because traffic conditions vary throughout the day.
Our recommendation is simple:
Give yourself substantially more time than you normally would.
If you have a 6:00 p.m. dining reservation, for example, your goal should be to be at Glen Iris Inn by 6:00 pm—not arriving at the Park at 6:00 pm.
Can the Park close an entrance or redirect traffic?
Yes. When visitation and traffic are high, Park staff may implement traffic management measures, including directing vehicles to different routes or entrances.
These decisions are based on conditions at the time and can change.
Please follow directions from Park staff and posted signage.
What if the route I normally use isn't available?
Follow the Park’s current traffic directions.
Don’t assume that the route you used on a previous visit—or the route recommended by your GPS—is the route you should use that day.
Park traffic conditions can change.
What if I'm running late for my reservation?
Most importantly, don’t put yourself or other drivers at risk by rushing. When you do arrive at the Glen Iris Inn, check in with us, and we will accommodate you as soon as possible.
Why don't you just tell guests exactly which entrance to use?
The best route can depend on current Park conditions.
We don’t want to give you information that may become outdated during the day. That’s why we recommend checking the Park’s current information immediately before your trip.
Is Letchworth State Park open in October?
Yes, Letchworth is a popular destination throughout the fall. However, access, traffic patterns, and visitor capacity can vary during peak periods.
Check current Park information before traveling.
Is October a good time to visit?
Absolutely!
October is one of the most spectacular times to visit Letchworth.
This information isn’t meant to discourage you from visiting. It’s to help you plan realistically so that traffic doesn’t become an unexpected part of your experience.
Come enjoy the foliage—just give yourself extra time.
For Overnight Hotel Guests
What should I know if I'm staying overnight at Glen Iris Inn?
The biggest thing to remember is that Glen Iris Inn is located inside Letchworth State Park.
Your journey doesn’t end when you reach the Park entrance. During peak October weekends, traffic within the Park can add significant time to your trip.
We recommend:
- Checking Park traffic and entrance information before leaving home.
- Allowing extra time for your drive through the Park.
- Arriving well before any dining, event, or activity reservations.
- Keeping your plans flexible during the busiest weekends.
- Following all Park traffic directions and signage. Remember, if you have your confirmation, it is best to go to the Portageville entrance and drive around the closure to the park gate, where the attendant will let you through.
- Avoid tight schedules that depend on arriving at a specific time.
What is the best entrance to access the Glen Iris Inn?
If you have an overnight or dining reservation at the Glen Iris Inn, bring your confirmation and go to the Portageville entrance at 6849 Park Road, Portageville, NY. If the entrance is closed, carefully drive around the barriers, show your confirmation to the gate attendant, and they will allow you through.
What time should I leave home for check-in?
Work backward from your desired arrival at the Inn, not simply from the Park entrance.
For example, if you need to check in at 4:00 p.m., don’t plan your trip around reaching Letchworth at 4:00 p.m.
Plan to arrive at the Inn by 4:00 p.m. and build additional time into your travel plans for Park traffic.
Can I leave the Inn and come back later?
Yes, but remember that traffic conditions can change during the day.
Be sure to have your confirmation and/or room key to be able to get back into the Park.
If you’re planning to leave the Park for dinner, shopping, or sightseeing elsewhere and return later, allow extra time for your return trip.
What if I arrive before check-in?
Arriving early can be helpful during peak periods, but please understand that early arrival does not guarantee that your room will be ready before the posted check-in time.
I'm staying several nights. Do I need to worry about October traffic every day?
Traffic levels can vary considerably by day and time.
Weekends and peak foliage periods are generally the times when visitors should be most prepared for congestion.
Even if your arrival was easy, conditions may be different when you head out or return later.
I have a hotel reservation and a Caroline's dining reservation. How much time should I leave between them?
More than you normally would.
If you’re checking in and dining at the Inn on the same day, give yourself a generous buffer between your planned arrival and your dinner reservation.
You don’t want your dining reservation to depend on a perfectly timed drive through a busy state park.

For Caroline’s Dining-Only Guests
I'm coming to Caroline's just for dinner. Do I really need to allow extra time?
Yes. On October weekends, plan for the possibility that getting through Letchworth State Park may take significantly longer than usual.
Your dining reservation time is when you need to be at Caroline’s, not when you should arrive at the Park.
I have a 7:00 p.m. reservation. When should I enter the Park?
We can’t provide a universal arrival time because traffic conditions vary.
We recommend building a generous cushion into your plans and checking current Park conditions before leaving.
Make sure you have your confirmation and enter through the Portageville entrance whenever possible. If the entrance is closed, drive carefully around the barriers, and the park attendant at the gate will let you through when you show your confirmation.
What if I arrive early?
That’s much better than arriving late!
If you arrive early, enjoy the Inn and the surrounding area, take in the scenery, or take time to relax before dinner.
Don’t cut your timing close during peak October weekends.
Can I use my normal route to Caroline's?
The normal access point for Glen Iris Inn is the Portageville Entrance, but Park traffic management may change how vehicles are directed during busy periods.
Check the Park’s current information before traveling.
My GPS says I'll arrive on time. Why should I leave earlier?
GPS may not anticipate temporary Park traffic controls or congestion.
During peak foliage weekends, the actual drive through the Park can take much longer than the normal travel time shown by your navigation app.
What happens if I'm late for my dining reservation?
Check in with us once you arrive, and we will do our best to accommodate you.
Please don’t speed or drive unsafely to make your reservation.
I'm coming with friends/family who are driving separately. What should I tell them?
Make sure everyone in your party knows:
“We’re meeting at Caroline’s—not at the Park entrance.”
Send them the Inn’s location and remind them to allow extra time for Park traffic. Make sure each vehicle has a copy of the confirmation so they can enter at the Portageville gate.
