The 1980 Olympic venues are all run by ORDA (the Olympic Regional Development Authority). They are worth seeing the summer and they all operate in the winter hosting major international competitions each year.
The Whiteface website covers all the Olympic venues. There is a lot to the LP Olympic facilities. A museum, world cup competitions, exhibition skating, tours of the venues. It is endless. Things change by the season too – for example, the x-country ski center becomes a mountain biking and horseback riding center in the summer. Whiteface uses its gondola to bring bikes up the hill for a big downhill run. There is professional coaching and training for Olympic hopefuls in many winter sports and also adult fantasy camps for things like luge. Spend some time looking around this site to find things suited to the season and your interests.
