I've gained weight recently and I'm concerned I won't be able to go on many of the rides if I go this summer. What is the average maximum weight for most of the rides?

About 220 is what most of the signs say that I saw.

There are very few weight restrictions at Silverwood! The few that there are are on the children's rides. The only issue you might have is the bars on some of the rides closing, but that usually isn't an issue either. If you go to their website look under rules and they have a height/weight restriction guide!

225 is the max for the rides, so it should be fine.
