Kelso Conservation Area has reopened its popular inflatable waterpark, Kelso Cove, for the 2025 summer season.
Located in Milton, Kelso Cove Waterpark features a giant inflatable structure with slides, climbing towers, obstacle courses, and bounce pads – a total of 26+ water features spread across an area of 50′ x 170′.
The park will be open from June 21st. Visitors can expect climbing elements, slides, and balance-testing obstacles. Certified National Lifeguard Service (NLS) lifeguards will be stationed on duty throughout the waterpark’s operating hours to ensure visitor safety.
Reservations are required for visitors aged 5 and older who meet the minimum height requirement of 4 feet and complete a swim test.
The Kelso Reservoir supports various activities throughout the year, from swimming and canoeing to paddleboarding. Visitors can also walk peacefully along the boardwalk around the reservoir.
Fishing enthusiasts can enjoy fly fishing, shoreline fishing, and non-motorized boat fishing, though live bait is not allowed.
Kelso Conservation Area transforms from the winter ski and snowboard hill, Glen Eden, into a hub for outdoor activities in spring, summer, and fall. In addition to water activities, visitors can hike or mountain bike on extensive trails, tackle the aerial courses, or enjoy a stroll on the stroller-friendly boardwalk around the lake.
Kelso Conservation Area, located at 5234 Kelso Road, is open daily from 9:00 am to 9:00 pm starting June 21, 2025.
