Picnic and play near the Columbia River
Trojan Park is a delightful day-use park with facilities for picnicking, hiking, biking, fishing, paddling and disc golf . The 75-acre park includes a stocked lake open to non-motorized boats, multi-use trails and a large sports field.
The park, near the site of the former Trojan Nuclear Power Plant, has individual picnic tables as well as facilities for groups: two shelter complexes, each with two reservable sections. Electric stoves, sinks, water and electrical outlets are provided.
The park has barrier-free restrooms and picnic sites.
Trojan Park's picnic areas, parking and restrooms are open seasonally:
Summer (Memorial Day weekend through Labor Day): Open Thursday through Monday
Remainder of September: open Friday through Sunday only.
The rest of the year, the picnic areas and restrooms are closed, but the disc golf course, ponds and trails are open year-round with limited services, parking and a portable toilet.

We’re committed to keeping our parks safe, clean, sustainable and welcoming – but we need your help.
Make a plan: Check for road closures, construction, fire bans, swimming restrictions or other conditions that may hamper your visit.
…and a plan B: Make a backup plan in case of crowds. Try visiting on weekdays or at off-peak times to beat the masses!
EV adventuring? While our parks do not have charging stations (yet!), check here for nearby locations that do.
Stop campfires from becoming wildfires! Keep campfires small, make sure your tent and anything that can burn is a safe distance from your fire, keep water nearby and never leave a fire unattended.
Keep it clear: Park only in designated areas. Do not double-park or block entrances.
Leave no trace: Help us protect these natural areas by staying on-trail, packing out your trash, and admiring wildlife from a distance.
