If you go
* Directions
Take Md. 64 east to Smithsburg and then Md. 77 east into Frederick County to Catoctin Hollow Road. Follow the signs to the main visitor area. For more information call 301-271-7574.
* Cost
Park entrance fee: $3.
* Times
The park opens at 8 a.m. and closes at sunset. The swimming areas are open between Memorial Day and Labor Day. The rangers suggest getting to the park before noon during the summer. Because of limited parking, you will be turned away if the park fills its 600 parking spaces.
* Things to do
It's a park, so you'll be outside and near water. Bring swim trunks and some walking shoes.
The half-mile trail to the falls is pretty light, so you don't need heavy hiking boots. You may want to bring them along for the other trails in the park. Most of the 10 regulated trails are labeled as "strenuous" hikes and range from the .75 miles to 27 miles.
