Scuba

What It Feels Like

Achensee is the most straightforward planned scuba base: its designated east-side sites include novice-friendly Schwarzenau and Hechenberg North, a club underwater trail at TCI Parcours and the advanced Hechenberg South wall. Around Fernpass, privately operated Blindsee and the restricted Fernsteinsee/Samaranger See offer different conditions and qualifications. Plansee offers separately permitted entries. Heiterwanger See is not an authorized scuba lake under the published Land Tirol diving order. See Achensee site guide, 2026 hotel rules and Plansee rules.

Operator Checklist

Book by actual lake, not by destination name. Carry certificate, recent logbook, medical fitness evidence if the operator/regulation requires it, and written permit; confirm dive-school authorization separately. Arrange your own buddy and adequate breathing gas unless a specific operator confirms a fill. Achensee Hotel Post am See advertises equipment and fills, but call ahead. Fernstein has no rental and no self-service compressor. Use local land-based staff for Plansee. The formal Plansee rules prohibit unapproved training and weighted apnea and prohibit all recreational scuba at Heiterwanger See. Verify any changes to the 2018 legal order before departure.
