The primary access to the Delta Heritage Trail is at Walnut Corner, about 6-miles west of Helena on U. S. Highway 49.
This is a gem of a trail! We biked the 12 miles from the visitor center to Lake View, then back. 90% of this trail section is shaded (though by noon there's more sun through the treetops). Biking on the morning of July 4th, the only other person we saw was a park ranger. The facilities at the visitor center are marvelous, and the historic information at the Lake View stop is educational and interesting. Make the effort, you'll enjoy this well maintained, beautiful, peaceful trail. Like for us, it might be just you and the dragonflies and butterflies!
My son and I went on a bike ride on the trail. Rode the first 18 miles all while doing a geocache' run. Clean, smooth, not busy. Most of all it was a peaceful ride.
Camping is OPEN since June 1st. Had a great night's stay here. Fee is $14, pay at front if no envelopes in the box. If beyond closing time, just pay in the morning. Sites are walk-in only, park vehicles in the parking lot. I suggest if you need water, use the refill station near the cycle repair spot in the parking lot. Sites are in excellent condition just watch out for the slippery wood lining the gravel. Highly reccomend coming here for a primitive night's stay!
