Ladies and Gentlemen:

         We have acted as counsel to Six Flags, Inc., a Delaware corporation
(the "Company"), in connection with the preparation and filing with the
Securities and Exchange Commission of the Company's Registration Statement on
Form S-4, Registration No. 333-60060 (as amended, the "Registration Statement"),
under the Securities Act of 1933, as amended, relating to $375,000,000 aggregate
principal amount of the Company's 9 1/2% Senior Notes due 2009 (the "Notes").

         In so acting, we have examined originals or copies, certified or
otherwise identified to our satisfaction, of the Registration Statement, the
Indenture dated as of February 2, 2001, between the Company and The Bank of New
York, as trustee (the "Trustee"), pursuant to which the Notes will be issued
(the "Indenture"), the form of the Notes included in the Indenture filed as
Exhibit 4.1 to the Registration Statement and such corporate records,
agreements, documents and other instruments, and such certificates or comparable
documents of public officials and of officers and representatives of the
Company, and have made such inquiries of such officers and representatives, as
we have deemed relevant and necessary as a basis for the opinion hereinafter set
forth.

         In such examination, we have assumed the genuineness of all signatures,
the legal capacity of natural persons, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified, conformed or photostatic copies and the
authenticity of the originals of such latter documents. As to all questions of
fact material to this opinion that have not been independently established, we
have relied upon certificates or comparable documents of officers and
representatives of the Company.

         Based on the foregoing, and subject to the qualifications stated
herein, we are of the opinion that the Notes are duly authorized, and, when duly
executed on behalf of the Company, authenticated by the Trustee and delivered in
accordance with the terms of the Indenture and as contemplated by the
Registration Statement, will constitute legal, valid and binding obligations of
the Company, enforceable against it in accordance with their terms, subject to
applicable bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and similar laws affecting creditors' rights and remedies generally,
and subject, as to enforceability, to general principles of equity, including
principals of commercial reasonableness, good faith and fair dealing (regardless
of whether enforcement is sought in a proceeding at law or in equity).

         We consent to the reference to our name under the caption "Legal
Matters" in the prospectus which is a part of the Registration Statement.


                                           Very truly yours,

                                           /s/ Weil, Gotshal & Manges LLP
