By round trip I presume you mean up from Wengen and down via Grindelwald or vice versa.
If you stayed at Lauterbrunnen and then went up to Jungfraujoch via Wengen then you could go back down to Grindelwald and cable cars across from Grindelwald to Wengen via Mannlichen and on to Lauterbrunnen. Or take train from Grindelwald to Zweilütschinen and back up to Lauterbrunnen.
If you are at Lauterbrunnen a very nice circuit to do is to Grütschalp (cable car), Mürren (cogwheel train), Gimmelwald (cable car), Stechelberg (cable car), Lauterbrunnen (bus). From Mürren you can easily visit Schilthorn. In between Stechelberg and Lauterbrunnen the bus stops at the Trummelbach Falls.
