Why do 4 parking spots, a portapotty, and a large open field, with a footbeaten walking trail justify a discovery pass, and need to enforce on technicalities necessary? It is a nice field

I fully appreciate the services provided at lake isabela park. Trails go forever. 2 gigantic fields. Connects multiple roads. Fishing access. Great place to run dogs on long lead. Don't go if you have a problem. Plenty of ways to benefit from this dream park if you can't afford a Discovery pass.

I agree. Seems silly to do that to a family on a holiday weekend during all the fuss. Especially when you have purchased said pass. Thanks for protecting Amercas parks one ticket at a time. I bet your parents are proud of what you've accomplished. Had 2 incorrectly displayed so stupid fee applies
