Shout out to Lynden, WA for having an impressive number of parks for its size. This one is technically available for camping but ONLY for youth groups, e.g. scouts and the like, and they need to be reserved and worked out with the city well in advance. The city will provide all necessary rules and regulations (like, tents only) but they aren’t super relevant to the general public, as if you aren’t in a youth group with a reservation you have to leave at dusk. This is true of all the other parks in Lynden too, so be aware.
