It has been a few years since I did this but from memory...
Big Bear City - 6,500' AMSL - nice restaurant onsite.
Catalina Island / Avalon
Santa Barbara - Lovely contrasting scenery from the Pacific Ocean and mountains to the north.
Palm Springs - Didn't know about the swimming pool but I will make sure I take my swimming trunks next time!
Sedona - As people have said before, 5,000' AMSL and the airport is on a plateu so it feels like a carrier landing (not that I've done a real carrier landing).
Grand Canyon Naitonal Park
Las Vegas McLarren International - Don't really have to provide a reason for this one!
Monterey - On the Pacific coast - lovely town, pier etc.
San Diego International - Five minute tram ride into the city centre
Half Moon Bay
Sacramento
One of the most memorable days was spent flying from Brackett to Catalina Island and then up to Big Bear City at 6,500' AMSL for lunch before flying onto Las Vegas McLarren International for a night stop.
The western states have fantastic and varied scenery... it definitely ticks the wow factor box for me.
Have a look at
AirNav for reviews of FBO's etc from users. Also includes up to date(ish) fuel prices etc.
