Sister Grove Park

Lake Lavon

This is a great little hidden away park on the very northern tip of Lake Lavon. From the park, there are no lake views. It is about a mile hike down to the lake. This park is mainly used by hikers and bikers for its native trail routes.

Sister Grove Park has a great day use area. There are plenty of covered picnic tables and a covered pavilion. There are some short paved trails in the day use area. The trails leading to the lake are unpaved.

Entry to the park is FREE.

This park and trails are part of the Dallas Off Road Bicycle Association (DORBA).

A great trail near the town of Farmersville, in a county park full of refreshing green trees and grass. You might spot small animals like tortoises, rabbits, and various birds. Sometimes wild flowers bloom along the trail. This is a popular spot for photography (nature photography, wedding photography, portraits).

The trail starts at the sidewalk going left from the trailhead restroom building. It follows the Puppy Dog Loop for about 1.5 miles. This is the easiest and shortest loop. It comes out at the Corp of Engineers sign which marks the trail junction of the 3 loops. The Lake Loop is next, going to the left and basically clockwise, returning to nearly the same point, and veers left to the Sister Loop (also marked with black and white signs), to take you along a scenic and challenging (up) hilly loop back to the parking lot. Enjoy!

Watch for hikers and dog-walkers, and beware of wild creatures. It is a nature trail, after all.

Watch for trail maintenance workers on weekends, and look on DORBA and social media for Sister Grove Trail events!
