Yes

The Rockefeller estate (Kykuit) is worth seeing.

You've got some great recommendations.

I don't think anyone has mentioned Mokhonk.
It's a pricey resort, but they allow day trippers (for a fee). It is breathtaking in the fall, highly recommend.

If you go to Bear Mountain, they have Octoberfest every year

Seven Lakes Drive is beautiful and worth driving if you do end up near Bear Mountain.

I think the prettiest view of the Hudson is in the Adirondacks. I would explore the northern part and work my way down. Schroon Lake, Lake George, Bolton Landing, North Creek, it runs in back of my brother's home. Great white water rafting, places to eat etc.

Abram - why didn't you like the Poets Park walk?

You're coming to this area a great time of the year. During the second week of October, you're bound to hit the peak foliage in at least part of your trip. That experience alone makes the trip a memorable one.

As for what to see, you've gotten some good suggestions. My A llst for the lower part of the Hudson Valley include these three sites:

*The FDR home and museum in Hyde Park. A $20 million renovation of the museum completed a year or so ago makes this site ever more of a "must see."

*Storm King Art Center in Cornwall is our favorite site in all of the Hudson Valley. And the foliage as part of the scene makes it even better.

*Kykuit, the Rockefeller estate in Pocantico Hills (adjacent to Tarrytown) is our pick as the best all the estates in the Hudson Valley.

Here is the schedule for Storm King. You are getting in just before closing time.

Thanks, again, everyone.

Storm King looks fascinating. I love that stone wall on their website!

Be sure to note closing days as many places are closed Mondays and Tuesdays and some inlcude Wednesday in closing days.

I wouldn't have thought of that, yestravel. Thanks for mentioning it and I'll keep it in mind.

Try to do Storm King on a weekday, as it gets crowded on weekends. And, allow yourself at least 2-3 hours to fully enjoy the experience. There is an outdoor cafe there, along with a picnic area.

Thanks, Howard. I'll keep that in mind when scheduling. I like the idea of a picnic.

Additional suggestion on how to best enjoy Storm King:

When you get there, take the tram which goes all around the facility, allowing riders to get on and off all along the circular route. Then, decide where you want to spend more time and either walk there or ride the tram again to the stop or stops in the area or areas where you want to spend more time.

I cannot overstate how wonderful the experience of Storm King is! We go at least twice every year and always find new joys and pleasure to experience. I'm a photographer and I never run out of subjects (or angles of the subjects) to photograph!

Thanks again, Howard!

We're not even museum/art aficionados and we LOVED Storm King!

To further prove my strong endorsement of Storm King, my wife and I took advantage of the beautiful weather today and went there! And, as usual, it was great! I must say that a weekday visit, with the much smaller crowds, is more of a joy!

For those of you who regularly go there, I encourage a return trip between now and through the end of October to see the special exhibit "Lynda Benglis: Water Sources,"
which includes several pieces "centered around the outdoor water fountains that the artist has been developing since the early 1980's."

No one has mentioned that the facility is only open five days a week--Wednesday through Sunday. In addition, it's open on two Mondays--Labor Day (September 7) and Columbus Day (October 12).

Minor correction: The facility is actually located in East Windsor, not Cornwall, as I originally wrote.

One final note: If you're free tomorrow, admission is free for the day!

Has an any one mentioned Storm King?

I'll see you Storm King and I'll raise you Seven Lakes and Bear Mountain - especially in October.

I lived in the Lower Hudson Valley for a few years, it can get nippy in October.

I've posted on Fodors in October and , it can get nippy
