More than 3,000 people visited Conister Rock on Sunday as part of an annual walk to the Tower of Refuge.
Sponsored by Tower Insuance the event was organised by Douglas Town Centre Management and supported by Douglas Coastguard.
Money raised was donated to the Royal National Lifeboat Institution.
Town Centre Manager Oliver Cheshire said: "Holding the event on a Sunday really drew the crowds, not only for the walk itself but also for all the free rides and live entertainment.
"We're very grateful to Tower Insurance for their continued sponsorship, to all those who served as marshals and, of course, to Kev Scott and his fellow Douglas Coastguard crew members, without whom we wouldn’t be able to stage the event.
"RNLI volunteers do tremendous work, not just saving lives but educating, too, so we’re pleased that all donations from the Tower of Refuge walk have gone to such a deserving cause."
Tower Insurance Managing Director Emmet McQuillan said: "Tower Insurance are proud to be supporting this event where people can take this rare opportunity to visit the Tower of Refuge, one of the Island's famous landmarks.
"The RNLI have been chosen by our staff as their charity of the year.
"Money raised today and from other events to celebrate our 90th anniversary will be used to support the lifesaving work of this very worthy charity."
