I think the best approach for the camping trip would be to keep the gear list pretty minimal. You mentioned you already have a tent and sleeping bags so that covers the big items. For cooking I would suggest bringing a single burner stove instead of building campfires since fire restrictions can be unpredictable. Plan your meals around things that don't need much refrigeration like tortillas with peanut butter and dried fruit for lunch. For dinners those pouch meals you just add hot water to work great. Bring layers because the temperature drops significantly after sunset even in summer. A headlamp is really useful for hands-free tasks around camp. I would also pack a basic first aid kit and make sure someone in the group has a way to call for help if needed. The park ranger station can provide current trail conditions and any wildlife advisories. Let me know if you want help sorting out the meal plan further.

I wanted to follow up on your question about the vegetable garden layout. Based on the space you described I think raised beds would give you better drainage and soil control than planting directly in the ground. A width of four feet lets you reach the center from both sides without stepping on the soil. For your first season I would recommend starting with tomatoes cucumbers and bell peppers since those are fairly resilient and produce steadily through summer. You will want to amend the soil with compost about two weeks before planting. Water deeply two to three times per week rather than light daily watering to encourage root growth. Mulching with straw or shredded leaves helps retain moisture and keeps weeds down. If you have deer in the area a simple fence about five feet tall should be enough to discourage them. I can send you the planting schedule I use if that would be helpful. Let me know what you decide on the bed configuration.
