LEONARDTOWN, Md. – After 23 years of aquatics fun at the Great Mills Swimming Pool, the St. Mary’s County Department of Recreation & Parks (R&P) will conclude operations at the facility on Thursday, April 30, 2026.

Public drop-in daily admission will remain available through the remainder of April at rate of $8 for adults and $6 for youth and seniors. Current Great Mills Swimming Pool pass holders will receive a 50% discount on daily admission rates to the pool. Any valid punch passes not redeemed at Great Mills Swimming Pool before April 30 can be redeemed at the Wellness & Aquatics Center in Leonardtown through their expiration date.
